素问·六元正纪大论 Comprehensive Discourse on the Correct Chronicle of the Six Origins

第 71 篇 / 共 81 篇

黄帝问曰:六化六变,胜复淫治,甘苦辛咸酸淡先后,余知之矣。夫五运之化,或从五气,或逆五气,或从天气而逆地气,或从地气而逆天气,或相得,或不相得,余未能明其事。欲通天之纪,从地之理,和其运,调其化,使上下合德,无相夺伦,天地升降,不失其宜,五运宣行,勿乖其政,调之正味,从逆柰何。歧伯稽首再拜对曰:昭乎哉问也。此天地之纲纪,变化之渊源,非圣帝孰能穷其至理欤,臣虽不敏,请陈其道,令终不灭,久而不易。帝曰:愿夫子推而次之,从其类序分其部主,别其宗司,昭其气数,明其正化,可得闻乎。歧伯曰:先立其年以明其气,金木水火土运行之数,寒暑燥湿风火临御之化,则天道可见,民气可调,阴阳卷舒,近而无惑,数之可数者,请遂言之。

帝曰:太阳之政柰何。歧伯曰:辰戌之纪也。

凡此太阳司天之政,气化运行先天,天气肃,地气静,寒临太虚,阳气不令,水土合德,上应辰星镇星。其谷玄黅,其政肃,其令徐。寒政大举,泽无阳焰,则火发待时。少阳中治,时雨乃涯,止极雨散,还于太阴,云朝北极,湿化乃布,泽流万物,寒敷于上,雷动于下,寒湿之气,持于气交。民病寒湿,发肌肉萎足痿不收濡写血溢。初之气,地气迁,气乃大温,草乃早荣,民乃厉,温病乃作,身热头痛呕吐,肌腠疮疡。二之气,大凉反至,民乃惨,草乃遇寒,火气遂抑,民病气郁中满,寒乃始。三之气,天政布,寒气行,雨乃降,民病寒,反热中,痈疽注下,心热瞀闷,不治者死。四之气,风湿交争,风化为雨,乃长乃化乃成,民病大热,少气肌肉萎足痿,注下赤白。五之气,阳复化,草乃长,乃化乃成,民乃舒。终之气,地气正,湿令行,阴凝太虚,埃昏郊野,民乃惨凄,寒风以至,反者孕乃死。故岁宜苦以燥之温之,必折其郁气,先资其化源,抑其运气,扶其不胜,无使暴过而生其疾,食岁谷以全其真,避虚邪以安其正。适气同异,多少制之,同寒湿者燥热化,异寒湿者燥湿化,故同者多之,异者少之,用寒远寒,用凉远凉,用温远温,用热远热,食宜同法。有假者反常,反是者病,所谓时也。

帝曰:善。阳明之政柰何。歧伯曰:卯酉之纪也。

阳明,少角,少阴,清热胜复同,同正商。丁卯岁会,丁酉,其运风清热。

凡此阳明司天之政,气化运行后天,天气急,地气明,阳专其令,炎暑大行,物燥以坚,淳风乃治,风燥横运,流于气交,多阳少阴,云趋雨府,湿化乃敷。燥极而泽,其谷白丹,闲谷命太者,其耗白甲品羽,金火合德,上应太白荧惑。其政切,其令暴,蛰虫乃见,流水不冰,民病咳嗌塞寒热发,暴振凓癃閟,清先而劲,毛虫乃死,热后而暴,介虫乃殃,其发躁胜复之作,扰而大乱,清热之气,持于气交。初之气,地气迁,阴始凝,气始肃,水乃冰,寒雨化,其病中热胀面目浮肿,善眠鼽衂嚏欠呕,小便黄赤,甚则淋。二之气,阳乃布,民乃舒,物乃生荣,厉大至,民善暴死。三之气,天政布,凉乃行,燥热交合,燥极而泽,民病寒热。四之气,寒雨降,病暴仆,振栗谵妄,少气嗌乾引饮及为心痛痈肿疮疡疟寒之疾,骨痿血便。五之气,春令反行,草乃生荣,民气和。终之气,阳气布,候反温,蛰虫来见,流水不冰,民乃康平,其病温,故食岁谷以安其气,食间谷以去其邪,岁宜以咸以苦以辛,汗之清之散之,安其运气,无使受邪,折其郁气,资其化源。以寒热轻重少多其制,同热者多天化,同清者多地化,用凉远凉,用热远热,用寒远寒,用温远温,食宜同法。有假者反之,此其道也。反是者,乱天地之经,扰阴阳之纪也。

帝曰:善。少阳之政柰何。歧伯曰:寅申之纪也。

少阳,太羽,厥阴,丙寅,丙申其运寒肃,其化凝惨凓冽,其变冰雪霜雹,其病寒浮肿。

太羽,太角,少徵,太宫,少商。

凡此少阳司天之政,气化运行先天,天气正,地气扰,风乃暴举,木偃沙飞,炎火乃流,阴行阳化,雨乃时应,火木同德,上应荧惑岁星。其谷丹苍,其政严,其令扰。故风热参布,云物沸腾,太阴横流,寒乃时至,凉雨并起。民病寒中,外发疮疡,内为泄满,故圣人遇之,和而不争。往复之作,民病寒热疟泄,聋瞑呕吐,上怫肿色变。初之气,地气迁,风胜乃摇,寒乃去,候乃大温,草木早荣。寒来不杀,温病乃起,其病气怫于上,血溢目赤,咳逆头痛血𡹌,脇满肤腠中疮。二之气,火反郁,白埃四起,云趋雨府,风不胜湿,雨乃零,民乃康。其病热郁于上,咳逆呕吐,疮发于中,胸嗌不利,头痛身热,昏愦脓疮。三之气,天政布,炎暑至,少阳临上,雨乃涯。民病热中,聋瞑血溢,脓疮咳呕,鼽衂渴嚏欠,喉痹目赤,善暴死。四之气,凉乃至,炎暑闲化,白露降,民气和平,其病满身重。五之气,阳乃去,寒乃来,雨降,气门乃闭,刚木早凋,民避寒邪,君子周密。终之气,地气正,风乃至,万物反生,霿雾以行。其病关闭不禁,心痛,阳气不藏而咳。抑其运气,赞所不胜,必折其郁气,先取化源,暴过不生,苛疾不起。故岁宜咸辛宜酸,渗之泄之,渍之发之,观气寒温以调其过,同风热者多寒化,异风热者少寒化,用热远热,用温远温,用寒远寒,用凉远凉,食宜同法,此其道也。有假者反之,反是者,病之阶也。

凡此太阴司天之政,气化运行后天,阴专其政,阳气退辟,大风时起,天气下降,地气上腾,原野昏霿,白埃四起,云奔南极,寒雨数至,物成于差夏。民病寒湿腹满身䐜愤胕肿,痞逆寒厥拘急,湿寒合德,黄黑埃昏,流行气交,上应镇星辰星。其政肃,其令寂,其谷黅玄。故阴凝于上,寒积于下,寒水胜火,则为冰雹,阳光不治,杀气乃行。故有馀宜高,不及宜下,有馀宜晚,不乃宜早,土之利,气之化也,民气亦从之,闲谷命其太也。初之气,地气迁,寒乃去,春气正,风乃来,生布万物以荣,民气条舒,风湿相薄,雨乃后。民病血溢,筋络拘强,关节不利,身重筋痿。二之气,大火正,物承化,民乃和,其病温厉大行,远近咸若,湿蒸相薄,雨乃时降。三之气,天政布,湿气降,地气腾,雨乃时降,寒乃随之。感于寒湿,则民病身重胕肿,胸腹满。四之气,畏火临,溽蒸化,地气腾,天气否隔,寒风晓暮,蒸热相薄,草木凝烟,湿化不流,则白露阴布,以成秋令。民病腠理热,血暴溢疟,心腹满热胪胀,甚则胕肿。五之气,惨令已行,寒露下,霜乃早降,草木黄落,寒气及体,君子周密,民病皮腠。终之气,寒大举,湿大化,霜乃积,阴乃凝,水坚冰,阳光不治,感于寒则病人关节禁固腰脽痛,寒湿推于气交而为疾也。必折其郁气,而取化源,益其岁气,无使邪胜,食岁谷以全其真,食闲谷以保其精。故岁宜以苦燥之温之,甚者发之泄之。不发不泄,则湿气外溢,肉溃皮拆而水血交流。必赞其阳火,令御甚寒,从气异同少多其判也,同寒者以热化,同湿者以燥化,异者少之,同者多之,用凉远凉,用寒远寒,用温远温,用热远热,食宜同法。假者反之,此其道也,反是者病也。

凡此少阴司天之政,气化运行先天,地气肃,天气明,寒交暑,热加燥,云驰雨府,湿化乃行,时雨乃降,金火合德,上应荧惑太白。其政明,其令切,其谷丹白。水火寒热持于气交而为病始也,热病生于上,清病生于下,寒热凌犯而争于中,民病咳喘,血溢血泄鼽嚏目赤眦疡,寒厥入胃心痛腰痛腹大,嗌乾肿上。初之气,地气迁,燥将去,寒乃始,蛰复藏,水乃冰,霜复降,风乃至,阳气郁,民反周密,关节禁固腰脽痛,炎暑将起,中外疮疡。二之气,阳气布,风乃行,春气以正,万物应荣,寒气时至,民乃和,其病淋,目瞑目赤,气郁于上而热。三之气,天政布,大火行,庶类蕃鲜,寒气时至,民病气厥心痛,寒热更作,咳喘目赤。四之气,溽暑至,大雨时行,寒热互至,民病寒热,嗌乾黄瘅,鼽衂饮发。五之气,畏火临,暑反至,阳乃化,万物乃生乃长荣,民乃康,其病温。终之气,燥令行,馀火内格,肿于上,咳喘甚则血溢,寒气数举,则霿雾翳,病生皮腠,内舍于脇,下连少腹而作寒中地将易也。必抑其运气,资其岁胜,折其郁发,先取化源,无使暴过而生其病也。食岁谷以全真气,食间谷以辟虚邪。岁宜咸以耎之,而调其上,甚则以苦发之,以酸收之,而安其下,甚则以苦泄之。适气同异而多少之,同天气者以寒清化,同地气者以温热化,用热远热,用凉远凉,用温远温,用寒远寒,食宜同法。有假则反,此其道也,反是者病作矣。

凡此厥阴司天之政,气化运行后天,诸同正岁,气化运行同天,天气扰,地气正,风生高远,炎热从之,云趋雨府,湿化乃行,风火同德,上应岁星荧惑。其政挠,其令速,其谷苍丹,闲谷言太者,其耗文角品羽。风燥火热,胜复更作,蛰虫来见,流水不冰,热病行于下,风病行于上,风燥胜复形于中。初之气,寒始肃,杀气方至,民病寒于右之下。二之气,寒不去,华雪水冰,杀气施化霜乃降,名草上焦,寒雨数至,阳复化,民病热于中。三之气,天政布,风乃时举,民病泣出耳鸣掉眩。四之气,溽暑湿热相薄争于左之上,民病黄瘅而为胕肿。五之气,燥湿更胜,沈阴乃布,寒气及体,风雨乃行。终之气,畏火司令,阳乃大化,蛰虫出见,流水不冰,地气大发,草生,人乃舒,其病温厉,必折其郁气,资其化源,赞其运气,无使邪胜,岁宜以辛调上,以咸调下,畏火之气无妄犯之,用温远温,用热远热,用凉远凉,用寒远寒,食宜同法。有假反常,此之道也,反是者病。

帝曰:善。夫子言可谓悉矣。然何以明其应乎。歧伯曰:昭乎哉问也。夫六气者,行有次,止有位,故常以正月朔日平旦视之,覩其位而知其所在矣。运有馀,其至先,运不及,其至后,此天之道,气之常也。运非有馀非不足,是谓正岁,其至当其时也。帝曰:胜复之气,其常在也,灾眚时至候也,柰何。歧伯曰:非气化者,是谓灾也。

帝曰:天地之数终始柰何。歧伯曰:悉乎哉问也。是明道也。数之始,起于上而终于下,岁半之前,天气主之,岁半之后,地气主之,上下交互,气交主之,岁纪毕矣。故曰位明气月可知乎,所谓气也。

帝曰:余司其事,则而行之,不合其数,何也。歧伯曰:气用有多少,化洽有盛衰,衰盛多少,同其化也。帝曰:愿闻同化何如。歧伯曰:风温春化同,热曛昏火夏化同,胜与复同,燥清烟露秋化同,云雨昏暝埃长夏化同,寒气霜雪冰冬化同,此天地五运六气之化,更用盛衰之常也。帝曰:五运行同天化者,命曰天符,余知之矣。愿闻同地化者,何谓也。歧伯曰:太过而同天化者三,不及而同天化者亦三,太过而同地化者三,不及而同地化者亦三,此凡二十四岁也。帝曰:愿闻其所谓也。歧伯曰:甲辰甲戌太宫,下加太阴,壬寅壬申太角,下加厥阴,庚子庚午太商,下加阳明,如是者三。癸巳癸亥少徵,下加少阳,辛丑辛未少羽,下加太阳,癸卯癸酉少徵,下加少阴,如是者三。戊子戊午太徵,上临少阴,戊寅戊申太徵,上临少阳,丙辰丙戌太羽,上临太阳,如是者三。丁巳丁亥少角,上临厥阴,乙卯乙酉少商,上临阳明,己丑己未少宫,上临太阴,如是者三。除此二十四岁,则不加不临也。帝曰:加者何谓。歧伯曰:太过而加同天符,不及而加同岁会也。帝曰:临者何谓。歧伯曰:太过不及,皆曰天符,而变行有多少,病形有微甚,生死有早晏耳。

帝曰:夫子言用寒远寒,用热远热,余未知其然也,愿闻何谓远。歧伯曰:热无犯热,寒无犯寒,从者和,逆者病,不可不敬畏而远之,所谓时兴六位也。帝曰:温凉何如。歧伯曰:司气以热,用热无犯,司气以寒,用寒无犯,司气以凉,用凉无犯,司气以温,用温无犯,闲气同其主无犯,异其主则小犯之,是谓四畏,必谨察之。帝曰:善。其犯者何如。歧伯曰:天气反时,则可依则,及胜其主则可犯,以平为期,而不可过,是谓邪气反胜者。故曰:无失天信,无逆气宜,无翼其胜,无赞其复,是谓至治。

帝曰:善。五运气行主岁之纪,其有常数乎。歧伯曰:臣请次之。

帝曰:善。五运之气,亦复岁乎。歧伯曰:郁极乃发,待时而作也。帝曰:请问其所谓也。歧伯曰:五常之气,太过不及,其发异也。帝曰:愿卒闻之。歧伯曰:太过者暴,不及者徐,暴者为病甚,徐者为病持。帝曰:太过不及,其数何如。歧伯曰:太过者其数成,不及者其数生,土常以生也。

帝曰:其发也何如。歧伯曰:土郁之发,岩谷震惊,雷殷气交,埃昏黄黑,化为白气,飘骤高深,击石飞空,洪水乃从,川流漫衍,田牧土驹。化气乃敷,善为时雨,始生始长,始化始成。故民病心腹胀,肠鸣而为数后,甚则心痛脇䐜,呕吐霍乱,饮发注下,胕肿身重。云奔雨府,霞拥朝阳,山泽埃昏。其乃发也,以其四气。云横天山,浮游生灭,怫之先兆。金郁之发,天洁地明,风清气切,大凉乃举,草树浮烟,燥气以行,霿雾数起,杀气来至,草木苍乾,金乃有声。故民病咳逆,心脇满,引少腹善暴痛,不可反侧,嗌乾面尘色恶。出泽焦枯,土凝霜卤,怫乃发也,其气五。夜零白露,林莽声凄,怫之兆也。水郁之发,阳气乃辟,阴气暴举,大寒乃至,川泽严凝,寒氛结为霜雪,甚则黄黑昏翳,流行气交,乃为霜杀,水乃见祥。故民病寒客心痛,腰脽痛,大关节不利,屈伸不便,善厥逆,痞坚腹满。阳光不治,空积沈阴,白埃昏暝,而乃发也,其气二火前后。太虚深玄,气犹麻散,微见而隐,色黑微黄,怫之先兆也。木郁之发,太虚埃昏,云物以扰,大风乃至,屋发折木,木有变。故民病胃脘当心而痛,上支两脇,鬲咽不通,食饮不下,甚则耳鸣眩转,目不识人,善暴僵仆。太虚苍埃,天山一色,或气浊色黄黑,郁若横云不起雨而乃发也,其气无常。长川草偃,柔叶呈阴,松吟高山,虎啸岩岫,怫之先兆也。火郁之发,太虚肿翳,大明不彰,炎火行,大暑至,山泽燔燎,材木流津,广厦腾烟,土浮霜卤,止水乃减,蔓草焦黄,风行惑言,湿化乃后。故民病少气疮疡痈肿,脇腹胸背,面首四支,䐜愤胪胀,疡痱呕逆,瘛瘲骨痛,节乃有动,注下温疟,腹中暴痛,血溢流注,精液乃少,目赤心热,甚则瞀闷懊憹,善暴死。刻终大温,汗濡玄府,其乃发也,其气四。动复则静,阳极反阴,湿令乃化乃成。华发水凝,山川冰雪焰阳午泽,怫之先兆也。有怫之应而后报也,皆观其极而乃发也,木发无时,水随火也。谨候其时,病可与期,失时反岁,五气不行,生化收藏,政无恒也。

帝曰:水发而雹雪,土发而飘骤,木发而毁折,金发而清明,火发而曛昧,何气使然。歧伯曰:气有多少,发有微甚,微者当其气,甚者兼其下,徵其下气而见可知也。

帝曰:善。五气之发,不当位者何也。歧伯曰:命其差。帝曰:差有数乎。歧伯曰:后皆三十度而有奇也。帝曰:气至而先后者何。歧伯曰:运太过则其至先,运不及则其至后,此候之常也。帝曰:当时而至者何也。歧伯曰:非太过,非不及,则至当时,非是者眚也。帝曰:善。气有非时而化者何也。歧伯曰:太过者,当其时,不及者,归其己胜也。帝曰:四时之气,至有早晏高下左右,其候何如。歧伯曰:行有逆顺,至有迟速,故太过者化先天,不及者化后天。帝曰:愿闻其行,何谓也。歧伯曰:春气西行,夏气北行,秋气东行,冬气南行。故春气始于下,秋气始于上,夏气始于中,冬气始于标,春气始于左,秋气始于右,冬气始于后,夏气始于前,此四时正化之常。故至高之地,冬气常在,至下之地,春气常在,必谨察之。帝曰:善。

黄帝问曰:五运六气之应见六化之正,六变之纪,何如。歧伯对曰:夫六气正纪,有化有变,有胜有复,有用有病,不同其候,帝欲何乎。帝曰:愿尽闻之。歧伯曰:请遂言之。夫气之所至也,厥阴所至为和平,少阴所至为暄,太阴所至为埃溽,少阳所至为炎暑,阳明所至为清劲,太阳所至为寒氛,时化之常也。

厥阴所至为风府,为璺启。少阴所至为火府,为舒荣。太阴所至为雨府,为员盈。少阳所至为热府,为行出。阳明所至为司杀府,为庚苍。太阳所至为寒府,为归藏。司化之常也。

厥阴所至为生化,少阴所至为荣化,太阴所至为濡化,少阳所至为茂化,阳明所至为坚化,太阳所至为藏化,布政之常也。

厥阴所至为飘怒太凉,少阴所至为大暄寒,太阴所至为雷霆骤注烈风,少阳所至为飘风燔燎霜凝,阳明所至为散落温,太阳所至为寒雪冰雹白埃,气变之常也。

厥阴所至为挠动,为迎随。少阴所至为高明焰,为曛。太阴所至为沈阴,为白埃,为晦暝。少阳所至为光显,为彤云,为曛。阳明所至为烟埃,为霜,为劲切,为凄鸣太阳所至为刚固,为坚芒为立,令行之常也。

厥阴所至为里急,少阴所至为疡胗身热,太阴所至为积饮否隔,少阳所至为嚏呕为疮疡,阳明所至为浮虚,太阳所至为屈伸不利,病之常也。厥阴所至为支痛,少阴所至为惊惑恶寒战栗谵妄,太阴所至为蓄满,少阳所至为惊躁瞀味暴病,阳明所至为鼽尻阴股膝髀腨䯒足病,太阳所至为腰痛,病之常也。厥阴所至为緛戾,少阴所至为悲妄衂蔑,太阴所至为中满霍乱吐下,少阳所至为喉痹耳鸣呕涌,阳明所至皴揭,太阳所至为寝汗痉,病之常也。厥阴所至为脇痛呕泄,少阴所至为语笑,太阴所至为重胕肿,少阳所至为暴注瞤瘛暴死,阳明所至为鼽嚏,太阳所至为流泄禁止,病之常也。

凡此十二变者,报德以德,报化以化,报政以政,报令以令,气高则高,气下则下,气后则后,气前则前,气中则中,气外则外,位之常也。故风胜则动,热胜则肿,燥胜则乾,寒胜则浮,湿胜则濡泄,甚则水闭胕肿,随气所在以言其变耳。

帝曰:愿闻其用也。歧伯曰:夫六气之用各归不胜而为化。故太阴雨化,施于太阳,太阳寒化,施于少阴,少阴热化,施于阳明,阳明燥化,施于厥阴,厥阴风化,施于太阴,各命其所在以徵之也。帝曰:自得其位何如。歧伯曰:自得其位,常化也。帝曰:愿闻所在也。歧伯曰:命其位而方,月可知也。帝曰:六位之气盈虚何如。歧伯曰:太少异也,太者之至徐而常,少者暴而亡。帝曰:天地之气,盈虚何如。歧伯曰:天气不足,地气随之,地气不足,天气从之,运居其中而常先也。恶所不胜,归所同和,随运归从而生其病也。故上胜则天气降而下,下胜则地气迁而上,多少而差其分,微者小差,甚者大差,甚则位易气交易,则大变生而病作矣。大要曰:甚纪五分,微纪七分,其差可见,此之谓也。

帝曰:善。论言热无犯热,寒无犯寒,余欲不远寒,不远热,柰何。歧伯曰:悉乎哉问也。发表不远热,攻里不远寒。帝曰:不发不攻而犯寒犯热,何如。歧伯曰:寒热内贼,其病益甚。帝曰:愿闻无病者何如。歧伯曰:无者生之,有者甚之。帝曰:生者何如。歧伯曰:不远热则热至,不远寒则寒至。寒至,则坚否腹满,痛急下利之病生矣。热至,则身热吐下霍乱,痈疽疮疡,瞀郁注下,瞤瘛肿胀,呕,鼽衂头痛,骨节变,肉痛血溢血泄,淋閟之病生矣。帝曰:治之柰何。歧伯曰:时必顺之,犯者治以胜也。黄帝问曰:妇人重身,毒之何如。歧伯曰:有故无殒,亦无殒也。帝曰:愿闻其故何谓也。歧伯曰:大积大聚,其可犯也,衰其太半而止,过者死。帝曰:善。郁之甚者治之柰何。歧伯曰:木郁达之,火郁发之,土郁夺之,金郁泄之,水郁折之,然调其气,过者折之,以其畏也,所谓写之。帝曰:假者何如。歧伯曰:有假其气,则无禁也。所谓主气不足客气胜也。帝曰:至哉圣人之道,天地大化运行之节,临御之纪,阴阳之政,寒暑之今,非夫子孰能通之,请藏之灵兰之室,署曰六元正纪,非斋戒不敢示,慎传也。

The Yellow Emperor asked: I already understand the six transformations and six changes of the qi, the ascendancy and revenge [between the five phases] and their excessive governance, and the proper order of the flavors — sweet, bitter, acrid, salty, sour, and bland. But as for the transformations of the five movements — how at times they follow the five qi and at times oppose them, how at times they follow the qi of heaven while opposing the qi of earth, or follow the qi of earth while opposing the qi of heaven, how at times they are mutually accordant and at times discordant — these matters I have not yet been able to grasp clearly. I wish to comprehend the order of heaven and follow the principles of earth, to harmonize the movements and regulate their transformations, so that upper and lower may unite in virtue without usurping one another's proper sequence, so that the rising and falling of heaven and earth do not lose their fitness, so that the five movements proceed and unfold without deviating from their governance, and so that the proper flavors may be regulated accordingly — how is this accordance and opposition to be understood? Qibo bowed his head twice and replied: How illuminating is this question! This is the guiding thread of heaven and earth, the very wellspring of transformation and change — who but a sage sovereign could fathom its ultimate principle? Though I am unworthy, allow me to set forth this Way, that it may never be extinguished and remain unaltered through the ages. The Emperor said: I wish master to arrange these matters in sequence, to sort them by category and divide their governing domains, to distinguish their respective offices, to clarify the numbers of their qi, and to make plain their correct transformations — may I hear of this? Qibo said: One must first establish the [stem-branch designation of the] year in order to clarify its qi — the numbered sequence of the movements of metal, wood, water, fire, and earth, and the transformations wrought by cold, heat, dryness, dampness, wind, and fire as they preside and govern. Then the Way of heaven becomes visible, the qi of the people can be regulated, the unfolding and contracting of yin and yang draw near [to understanding] without confusion, and what can be enumerated can indeed be enumerated. Allow me now to set this forth in full.

The Emperor asked: What is the governance of greater yang [as controller of heaven]? Qibo replied: This is the chronicle of the chen and xu years [the dragon and dog earthly branches].

Greater yang governs heaven, with great wood as the central movement and greater yin governing earth, in the renchen and renxu years (ren being a yang wood heavenly stem, chen the dragon and xu the dog earthly branches). Its movement is wind; its transformation manifests as resounding turbulence, as things bursting open and splitting forth; its pathological excess manifests as violent shaking, uprooting, snapping, and toppling; its disease manifests as dizziness, tremor, and dimness of vision.

Great wood, lesser fire, great earth, lesser metal, great water.

Greater yang governs heaven, with great fire as the central movement and greater yin governing earth, in the wuchen and wuxu years (wu being a yang fire heavenly stem), which are of the same [influence] as an unmodified great-fire year. Its movement is heat; its transformation manifests as warmth, summer-heat, and stifling sultriness; its pathological excess manifests as blazing conflagration and seething ebullition; its disease manifests as heat stagnation.

Great fire, lesser earth, great metal, lesser water, lesser wood.

Greater yang governs heaven, with great earth as the central movement and greater yin governing earth, in the jiachen and jiaxu years (jia being a yang wood stem), both of which are 'year-conjunction' years [suihui, where the stem-governed movement matches the branch-governed qi of the year]. Its movement is yin turbidity and dust-laden mist; its transformation manifests as softening moisture and heavy, saturating dampness; its pathological excess manifests as startling tremors and sudden squalls; its disease manifests as dampness and heaviness in the lower body.

Great earth, lesser metal, great water, great wood, lesser fire.

Greater yang governs heaven, with great metal as the central movement and greater yin governing earth, in the gengchen and gengxu years (geng being a yang metal stem). Its movement is coolness; its transformation manifests as fog, dew, and the soughing of the autumn wind; its pathological excess manifests as stern killing and withering decay; its disease manifests as dryness, oppression of the back, dizziness, and fullness in the chest.

Great metal, lesser water, lesser wood, great fire, lesser earth.

Greater yang governs heaven, with great water as the central movement and greater yin governing earth, in the bingchen and bingxu years (bing being a yang fire stem), both being 'heaven-conjunction' years [tianfu, where the stem-governed movement matches the qi governing heaven]. Its movement is cold; its transformation manifests as congealing, bleak, biting chill; its pathological excess manifests as ice, snow, frost, and hail; its disease manifests as severe cold lodging in the valleys [of the muscles, i.e., the interstices between the large muscle masses].

Great water, great wood, lesser fire, great earth, lesser metal.

In all years when greater yang governs heaven in this manner, the transformation and movement of qi run ahead of the heavenly [calendrical] schedule. The qi of heaven is stern and the qi of earth is still; cold descends upon the great void and the yang qi cannot exercise its command; water and earth unite in virtue, corresponding above to the stars Chenxing [Mercury] and Zhenxing [Saturn]. Its grains are the black and the yellow; its governance is stern; its ordinances are unhurried. When the governance of cold is greatly asserted, the marshes show no trace of the fiery blaze [of summer], so that fire, when it does arise, must await its proper time. Lesser yang governs from within, so that seasonal rains reach their limit; when the rain ceases at its extreme it reverts to greater yin, clouds gather toward the northern pole, and the transformation of dampness spreads abroad, its moisture flowing to nourish the myriad things; cold spreads above while thunder stirs below, and the qi of cold and dampness contend within the qi-intersection [the meeting zone between the qi of heaven and earth]. The people suffer illness from cold and dampness, with wasting of the flesh, flaccidity and non-function of the legs, diarrhea with undigested food, and blood overflow. In the first [seasonal] qi, as the qi of earth shifts, the qi becomes greatly warm and plants flourish early; the people suffer pestilential illness, warm-disease arises, with fever, headache, vomiting, and sores in the flesh and interstices. In the second qi, unseasonable great coolness arrives instead; the people become subdued, plants encounter cold, and fire qi is thereby suppressed; the people suffer from stagnation of qi and fullness in the middle, and cold begins to set in. In the third qi, the governance of heaven is displayed, cold qi circulates, and rain descends; the people suffer from cold that instead produces heat in the interior, with welling-abscesses and flushing discharge, heat in the heart, dizziness and oppression — those not treated will die. In the fourth qi, wind and dampness contend with one another; wind transforms into rain, so that growth, transformation, and maturation proceed; the people suffer from great heat, shortness of qi, wasting of the flesh, flaccidity of the legs, and discharge of red and white [matter, i.e., dysenteric flux]. In the fifth qi, yang returns to transform, plants grow further, and transformation and maturation proceed; the people become at ease. In the final qi, the qi of earth is rectified, the ordinance of dampness circulates, yin congeals in the great void, dust-laden mist darkens the countryside, and the people become sorrowful and bleak; cold winds arrive, and where this is contrary [i.e. where warmth intrudes], pregnancies will miscarry and die. Therefore in such years one should use the bitter flavor to dry and to warm; one must break the stagnant qi, first replenishing its source of transformation, restraining the movement-qi [that is excessive] and supporting that which it overcomes, so as not to allow sudden excess to generate disease. Eat the grain proper to the year to preserve one's true qi, and avoid vacuity-evils so as to secure one's true [qi]. Adjust according to whether the qi is concordant or discordant [with the season], regulating by more or less: where cold and dampness coincide, use drying and heating transformation; where they diverge, use drying and dampening transformation — thus where they coincide, use more [of the corrective], where they diverge, use less. When employing cold [remedies], avoid [administering them in] cold [seasons]; when employing cool remedies, avoid cool seasons; when employing warm remedies, avoid warm seasons; when employing hot remedies, avoid hot seasons — diet should follow the same rule. Where there is a false [semblance contrary to the true pattern], one may act contrary to the norm; to act contrary to this [principle] causes disease — this is what is meant by 'according to the season.'

The Emperor said: Good. What is the governance of yang brightness [as controller of heaven]? Qibo replied: This is the chronicle of the mao and you years [the rabbit and rooster earthly branches].

Yang brightness governs heaven, with lesser wood as the central movement and lesser yin governing earth; coolness and heat, ascendancy and revenge, follow the same pattern [in these years], equivalent to an unmodified great-metal year. In the dingmao year — a year-conjunction year — and the dingyou year, the movement progresses from wind to coolness to heat.

Lesser wood, great fire, lesser earth, great metal, lesser water.

Yang brightness governs heaven, with lesser fire as the central movement and lesser yin governing earth; cold and rain, ascendancy and revenge, follow the same pattern, equivalent to an unmodified great-metal year. In the guimao and guiyou years, the movement progresses from heat to cold to rain.

Lesser fire, great earth, lesser metal, great water, great wood.

Yang brightness governs heaven, with lesser earth as the central movement and lesser yin governing earth; wind and coolness, ascendancy and revenge, follow the same pattern. In the jimao and jiyou years, the movement progresses from rain to wind to coolness.

Lesser earth, great metal, lesser water, lesser wood, great fire.

Yang brightness governs heaven, with lesser metal as the central movement and lesser yin governing earth; heat and cold, ascendancy and revenge, follow the same pattern, equivalent to an unmodified great-metal year. The yimao year is a heaven-conjunction year, and the yiyou year is both a year-conjunction and a supreme-unity heaven-conjunction year; the movement progresses from coolness to heat to cold.

Lesser metal, great water, great wood, lesser fire, great earth.

Yang brightness governs heaven, with lesser water as the central movement and lesser yin governing earth; rain and wind, ascendancy and revenge, follow the same pattern — in the xinmao year this accords with a lesser-earth [movement]. In the xinyou and xinmao years, the movement progresses from cold to rain to wind.

Lesser water, lesser wood, great fire, great earth, great metal.

In all years when yang brightness governs heaven in this manner, the transformation and movement of qi run behind the heavenly schedule. The qi of heaven is urgent and the qi of earth is bright; yang exclusively exercises command, and blazing summer-heat prevails widely, so that things become dry and hardened, while a pure wind governs. Wind and dryness circulate crosswise, flowing through the qi-intersection; yang is abundant and yin scant; clouds hasten toward the chambers of rain, and the transformation of dampness thereby spreads. When dryness reaches its extreme, moisture follows. Its grains are the white and the red; among the supplementary grains, that governed by the greater [movement dominates]; its depleted creatures are the white-shelled and the feathered species. Metal and fire unite in virtue, corresponding above to the stars Taibai [Venus] and Yinghuo [Mars]. Its governance is sharp and its ordinances sudden; hibernating creatures appear, and flowing water does not freeze. The people suffer cough, obstruction of the throat, alternating cold and heat, sudden shivering, chill, and urinary blockage. When coolness precedes and is forceful, the furred creatures perish; when heat follows and is sudden, the shelled creatures suffer calamity. Its outbreaks of restless ascendancy-and-revenge cause turmoil and great disorder; the qi of coolness and heat contend within the qi-intersection. In the first qi, as the qi of earth shifts, yin begins to congeal and the qi begins to turn stern; water freezes and cold rain forms in transformation; the people suffer from heat in the middle with swelling, puffy swelling of the face and eyes, excessive sleepiness, nasal obstruction, nosebleed, sneezing, yawning, and vomiting, with yellow-red urine, and in severe cases painful urinary dribbling. In the second qi, yang spreads abroad and the people become at ease; things grow and flourish, yet pestilence arrives in force and the people are prone to sudden death. In the third qi, the governance of heaven is displayed, coolness circulates, dryness and heat intermingle, and when dryness reaches its extreme moisture follows; the people suffer alternating cold and heat. In the fourth qi, cold rain descends; illness manifests as sudden collapse, shivering and delirious raving, shortness of qi, dry throat with craving for drink, as well as heart pain, welling-abscess swelling, sores, malarial cold disorders, wasting of the bones, and bloody stool. In the fifth qi, the ordinance of spring is reversed and prevails; plants grow and flourish, and the people's qi is harmonious. In the final qi, yang qi spreads abroad, the season turns unseasonably warm, hibernating creatures emerge, and flowing water does not freeze; the people are healthy and at peace, though warm disease may occur. Therefore eat the grain proper to the year to settle the qi, and eat the supplementary grains to dispel evil qi. In such years one should use salty, bitter, and acrid flavors, to sweat, to clear, and to disperse, so as to settle the movement-qi and prevent the reception of evil, to break stagnant qi, and to replenish the source of transformation. Regulate according to the lightness or severity of cold and heat, using more or less accordingly: where heat coincides [with the heavenly qi], favor transformation governed by heaven; where coolness coincides [with the earthly qi], favor transformation governed by earth. When employing cool remedies avoid cool seasons; when employing hot remedies avoid hot seasons; when employing cold remedies avoid cold seasons; when employing warm remedies avoid warm seasons — diet should follow the same rule. Where there is a false [semblance], act contrary to this — such is the Way. To act contrary to this principle throws into disorder the constant thread of heaven and earth, and disturbs the chronicle of yin and yang.

The Emperor said: Good. What is the governance of lesser yang [as controller of heaven]? Qibo replied: This is the chronicle of the yin and shen years [the tiger and monkey earthly branches].

Lesser yang governs heaven, with great wood as the central movement and reverting yin governing earth, in the renyin and renshen years. Its movement is wind that stirs and drums; its transformation manifests as resounding turbulence, things bursting open and splitting forth; its pathological excess manifests as violent shaking, uprooting, snapping, and toppling; its disease manifests as tremor, dizziness, pain in the limbs and ribsides, and fright.

Great wood, lesser fire, great earth, lesser metal, great water.

Lesser yang governs heaven, with great fire as the central movement and reverting yin governing earth, in the wuyin and wushen years, both heaven-conjunction years. Its movement is summer-heat; its transformation manifests as warmth, clamor, and stifling sultriness; its pathological excess manifests as blazing conflagration and seething ebullition; its disease manifests as heat stagnating above, overflow and discharge of blood, and heart pain.

Great fire, lesser earth, great metal, lesser water, lesser wood.

Lesser yang governs heaven, with great earth as the central movement and reverting yin governing earth, in the jiayin and jiashen years. Its movement is overcast rain; its transformation manifests as softening moisture and heavy, saturating dampness; its pathological excess manifests as startling tremors and sudden squalls; its disease manifests as heaviness of the body, puffy swelling, focal distention, and fluid retention.

Great earth, lesser metal, great water, great wood, lesser fire.

Lesser yang governs heaven, with great metal as the central movement and reverting yin governing earth, in the gengyin and gengshen years, equivalent to an unmodified great-metal year. Its movement is coolness; its transformation manifests as fog, dew, and clear, cutting [air]; its pathological excess manifests as stern killing and withering decay; its disease manifests [as disorders of] the shoulders, back, and chest.

Great metal, lesser water, lesser wood, great fire, lesser earth.

Lesser yang governs heaven, with great water as the central movement and reverting yin governing earth, in the bingyin and bingshen years. Its movement is cold severity; its transformation manifests as congealing, bleak, biting chill; its pathological excess manifests as ice, snow, frost, and hail; its disease manifests as cold with puffy swelling.

Great water, great wood, lesser fire, great earth, lesser metal.

In all years when lesser yang governs heaven in this manner, the transformation and movement of qi run ahead of the heavenly schedule. The qi of heaven is upright while the qi of earth is turbulent; wind arises suddenly and violently, bending trees and driving sand aloft; blazing fire then flows forth. Yin proceeds while yang transforms, and seasonal rains respond in due time; fire and wood unite in virtue, corresponding above to the stars Yinghuo [Mars] and Suixing [Jupiter]. Its grains are the red and the blue-green; its governance is severe and its ordinances turbulent. Thus wind and heat spread together, clouds and vapors seethe, greater yin [dampness] flows crosswise, cold arrives from time to time, and coolness and rain arise together. The people suffer cold in the interior, with sores erupting externally and diarrhea and fullness internally; the sage, meeting with this, harmonizes with it rather than contending against it. As [wind and cold] alternately advance and retreat, the people suffer alternating cold and heat, malarial disorders, diarrhea, deafness, blurred vision, vomiting, and swelling and discoloration above, with a sense of oppression. In the first qi, as the qi of earth shifts, wind prevails and causes shaking; cold then departs, the season turns greatly warm, and plants and trees flourish early. Cold that arrives does not kill, and warm disease then arises; the disease manifests as oppressed qi rising above, overflow of blood, redness of the eyes, coughing counterflow, headache, [nose]bleeding, fullness of the ribsides, and sores in the skin and interstices. In the second qi, fire is instead suppressed, white dust rises on all sides, clouds hasten toward the chambers of rain, wind cannot overcome dampness, and rain falls; the people are at ease. The disease manifests as heat stagnating above, coughing counterflow, vomiting, sores erupting within, discomfort of the chest and throat, headache, fever, clouded confusion, and purulent sores. In the third qi, the governance of heaven is displayed, blazing summer-heat arrives, lesser yang presides above, and rain reaches its limit. The people suffer heat in the interior, deafness, blurred vision, overflow of blood, purulent sores, coughing and vomiting, nasal obstruction, nosebleed, thirst, sneezing, yawning, painful throat obstruction, red eyes, and are prone to sudden death. In the fourth qi, coolness arrives, blazing summer-heat is interspersed in its transformation, white dew descends, and the people's qi is harmonious and at peace, though the disease may manifest as fullness and heaviness of the body. In the fifth qi, yang then departs and cold arrives; rain descends, the pores [qi-gates] close, hardy trees wither early; the people avoid the evil of cold, and the noble person keeps himself well guarded. In the final qi, the qi of earth is rectified, wind arrives, the myriad things paradoxically grow anew, and dense fog and mist prevail. The disease manifests as inability to control the joints and orifices, heart pain, and coughing from failure of yang qi to be stored. One must restrain the excessive movement-qi and assist that which it overcomes; one must break the stagnant qi, first drawing upon the source of transformation, so that sudden excess does not arise and severe disease does not develop. Therefore in such years salty and acrid flavors are suitable, as is the sour; use draining and discharging, soaking and dispersing methods, observing whether the qi is cold or warm in order to regulate its excess. Where wind and heat coincide, favor cold-natured transformation more; where they diverge, favor it less. When employing hot remedies avoid hot seasons; when employing warm remedies avoid warm seasons; when employing cold remedies avoid cold seasons; when employing cool remedies avoid cool seasons — diet should follow the same rule. Such is the Way. Where there is a false [semblance], act contrary to this; to act contrary to this principle is the very stairway to disease.

The Emperor said: Good. What is the governance of greater yin [as controller of heaven]? Qibo replied: This is the chronicle of the chou and wei years [the ox and sheep earthly branches].

Greater yin governs heaven, with lesser wood as the central movement and greater yang governing earth; coolness and heat, ascendancy and revenge, follow the same pattern, equivalent to an unmodified great-earth year. In the dingchou and dingwei years, the movement progresses from wind to coolness to heat.

Lesser wood, great fire, lesser earth, great metal, lesser water.

Greater yin governs heaven, with lesser fire as the central movement and greater yang governing earth; cold and rain, ascendancy and revenge, follow the same pattern. In the guichou and guiwei years, the movement progresses from heat to cold to rain.

Lesser fire, great earth, lesser metal, great water, great wood.

Greater yin governs heaven, with lesser earth as the central movement and greater yang governing earth; wind and coolness, ascendancy and revenge, follow the same pattern, equivalent to an unmodified great-earth year. Both the jichou and jiwei years are supreme-unity heaven-conjunction years; the movement progresses from rain to wind to coolness.

Lesser earth, great metal, lesser water, lesser wood, great fire.

Greater yin governs heaven, with lesser metal as the central movement and greater yang governing earth; heat and cold, ascendancy and revenge, follow the same pattern. In the yichou and yiwei years, the movement progresses from coolness to heat to cold.

Lesser metal, great water, great wood, lesser fire, great earth.

Greater yin governs heaven, with lesser water as the central movement and greater yang governing earth; rain and wind, ascendancy and revenge, follow the same pattern, equivalent to an unmodified great-earth year. In the xinchou and xinwei years, the movement progresses from cold to rain to wind.

Lesser water, lesser wood, great fire, lesser earth, great metal.

In all years when greater yin governs heaven in this manner, the transformation and movement of qi run behind the heavenly schedule. Yin exclusively exercises its governance and yang qi retreats and withdraws; great winds arise from time to time, the qi of heaven descends and the qi of earth rises, the open plains grow dark with mist, white dust rises on every side, clouds race toward the southern pole, cold rain arrives repeatedly, and things reach maturity only belatedly in summer. The people suffer from cold and dampness, with abdominal fullness, distention and puffy swelling of the body, focal distention and counterflow, cold reversal, and contracture; dampness and cold unite in virtue, and yellow-black dust darkens [the sky], circulating through the qi-intersection, corresponding above to the stars Zhenxing [Saturn] and Chenxing [Mercury]. Its governance is stern and its ordinances silent; its grains are the yellow and the black. Thus yin congeals above while cold accumulates below; when cold water overcomes fire, ice and hail form; when the light of yang fails to govern, killing qi then circulates. Thus where there is excess, high ground is favorable; where there is insufficiency, low ground is favorable; where there is excess, [planting and harvest is] appropriately late; where there is insufficiency, appropriately early — this is the benefit of earth and the transformation of qi, which the people's qi also follows; among the supplementary grains, that governed by the greater [movement] should be designated. In the first qi, as the qi of earth shifts, cold departs, the qi of spring is rectified, wind arrives, growth spreads over the myriad things bringing them to flourish, and the people's qi is at ease and unfolds freely; wind and dampness contend with one another, and rain therefore comes late. The people suffer overflow of blood, tightness and stiffness of the sinews and vessels, disfunction of the joints, heaviness of the body, and flaccidity of the sinews. In the second qi, the great fire [of summer] is rectified, things receive its transforming influence, and the people are harmonious; yet pestilential warm disease spreads widely, afflicting near and far alike; dampness and steam contend with one another, and rain falls at its proper season. In the third qi, the governance of heaven is displayed, dampness qi descends while the qi of earth rises, rain falls at its proper season, and cold follows in its wake. Those affected by cold and dampness suffer heaviness of the body, puffy swelling, and fullness of the chest and abdomen. In the fourth qi, the dreaded fire [of the interim] presides, sultry steaming transformation occurs, the qi of earth rises while the qi of heaven is blocked and obstructed; cold wind blows at dawn and dusk, steam and heat contend with one another, plants and trees are wrapped in condensed mist, and the transformation of dampness fails to flow freely; then white dew spreads its shade, bringing on the ordinance of autumn. The people suffer heat in the interstices, sudden overflow of blood, malarial disorders, fullness and heat of the heart and abdomen with distention, and in severe cases puffy swelling. In the fifth qi, the bleak ordinance [of autumn] has already taken hold, cold dew descends, frost falls early, plants and trees turn yellow and shed their leaves, and cold qi reaches the body; the noble person keeps himself well guarded, while the people suffer disorders of the skin and interstices. In the final qi, cold asserts itself greatly and dampness transforms greatly; frost accumulates, yin congeals, and water hardens into ice; the light of yang fails to govern. Those affected by cold suffer restriction and rigidity of the joints and pain of the lower back and buttocks; cold and dampness press upon the qi-intersection and give rise to illness. One must break the stagnant qi and draw upon the source of transformation, augmenting the qi of the year so as not to let evil qi prevail; eat the grain proper to the year to preserve one's true qi, and eat the supplementary grains to safeguard one's essence. Therefore in such years the bitter flavor should be used to dry and to warm; in severe cases, use methods of releasing and discharging. If one neither releases nor discharges, then damp qi will overflow externally, the flesh will fester and the skin split, with water and blood flowing together. One must assist the yang fire so as to withstand severe cold, judging by more or less according to whether the qi coincides or diverges: where cold coincides, use heat-natured transformation; where dampness coincides, use drying transformation; where they diverge, use less; where they coincide, use more. When employing cool remedies avoid cool seasons; when employing cold remedies avoid cold seasons; when employing warm remedies avoid warm seasons; when employing hot remedies avoid hot seasons — diet should follow the same rule. Where there is a false [semblance], act contrary to this — such is the Way. To act contrary to this principle causes disease.

The Emperor said: Good. What is the governance of lesser yin [as controller of heaven]? Qibo replied: This is the chronicle of the zi and wu years [the rat and horse earthly branches].

Lesser yin governs heaven, with great wood as the central movement and yang brightness governing earth, in the renzi and renwu years. Its movement is wind that stirs and drums; its transformation manifests as resounding turbulence, things bursting open and splitting forth; its pathological excess manifests as violent shaking, uprooting, snapping, and toppling; its disease manifests as fullness of the limbs.

Great wood, lesser fire, great earth, lesser metal, great water.

Lesser yin governs heaven, with great fire as the central movement and yang brightness governing earth. The wuzi year is a heaven-conjunction year, and the wuwu year is a supreme-unity heaven-conjunction year. Its movement is blazing summer-heat; its transformation manifests as warm brilliance and stifling sultriness; its pathological excess manifests as blazing conflagration and seething ebullition; its disease manifests as heat above with overflow of blood.

Great fire, lesser earth, great metal, lesser water, lesser wood.

Lesser yin governs heaven, with great earth as the central movement and yang brightness governing earth, in the jiazi and jiawu years. Its movement is overcast rain; its transformation manifests as softening moisture and timely rain; its pathological excess manifests as startling tremors and sudden squalls; its disease manifests as fullness in the middle and heaviness of the body.

Great earth, lesser metal, great water, great wood, lesser fire.

Lesser yin governs heaven, with great metal as the central movement and yang brightness governing earth, in the gengzi and gengwu years, equivalent to an unmodified great-metal year. Its movement is severe coolness; its transformation manifests as fog, dew, and the soughing of the autumn wind; its pathological excess manifests as stern killing and withering decay; its disease manifests as coldness below.

Great metal, lesser water, lesser wood, great fire, lesser earth.

Lesser yin governs heaven, with great water as the central movement and yang brightness governing earth. The bingzi year is a year-conjunction year, and there is also the bingwu year. Its movement is cold; its transformation manifests as congealing, bleak, biting chill; its pathological excess manifests as ice, snow, frost, and hail; its disease manifests as cold below.

Great water, great wood, lesser fire, great earth, lesser metal.

In all years when lesser yin governs heaven in this manner, the transformation and movement of qi run ahead of the heavenly schedule. The qi of earth is stern and the qi of heaven is bright; cold intermingles with summer-heat, heat is added to dryness; clouds race toward the chambers of rain, the transformation of dampness circulates, and seasonal rain descends; metal and fire unite in virtue, corresponding above to the stars Yinghuo [Mars] and Taibai [Venus]. Its governance is bright and its ordinances sharp; its grains are the red and the white. Water and fire, cold and heat, contend within the qi-intersection, and this is where disease begins: heat disease arises above, cold disease arises below, and cold and heat encroach upon and contend within the middle. The people suffer cough and panting, overflow and discharge of blood, nasal obstruction, sneezing, red eyes with sores at the canthi, cold reversal entering the stomach, heart pain, lower back pain, abdominal distention, dry throat, and swelling above. In the first qi, as the qi of earth shifts, dryness is about to depart and cold begins; hibernating creatures return to their burrows, water freezes, frost again descends, and wind arrives; yang qi becomes stagnant, and the people, contrary [to expectation], guard themselves closely; the joints become rigid and restricted, and the lower back and buttocks ache; blazing summer-heat is about to arise, and sores erupt both within and without. In the second qi, yang qi spreads abroad, wind circulates, the qi of spring is rectified, and the myriad things flourish in response; cold qi arrives from time to time, and the people are at ease, though they suffer painful urinary dribbling, blurred vision, red eyes, and heat from qi stagnating above. In the third qi, the governance of heaven is displayed, the great fire [of summer] circulates, and the multitude of creatures flourish luxuriantly; cold qi arrives from time to time, and the people suffer qi reversal, heart pain, alternating cold and heat, cough, panting, and red eyes. In the fourth qi, sultry summer-heat arrives, great rains fall at their season, and cold and heat arrive by turns; the people suffer alternating cold and heat, dry throat, jaundice, nasal obstruction, nosebleed, and fluid-retention disorders. In the fifth qi, the dreaded fire [of the interim] presides and summer-heat unexpectedly returns; yang then transforms, and the myriad things grow, mature, and flourish; the people are healthy, though warm disease may occur. In the final qi, the ordinance of dryness circulates, and the remaining fire is blocked within, causing swelling above; coughing and panting, in severe cases, bring overflow of blood; cold qi repeatedly asserts itself, so that dense fog and mist obscure [the sky]; disease arises in the skin and interstices, lodges internally in the ribsides, and extends downward to the lesser abdomen, producing cold in the interior as the earth [qi] is about to change. One must restrain the excessive movement-qi and draw support from what the year's qi overcomes, breaking the outbreak of stagnant qi and first drawing upon the source of transformation, so as not to let sudden excess give rise to disease. Eat the grain proper to the year to preserve the true qi, and eat the supplementary grains to ward off vacuity evils. In such years the salty flavor should be used to soften, thereby regulating the upper [body]; in severe cases use the bitter flavor to release, and the sour flavor to astringe, thereby settling the lower [body]; in severe cases use the bitter flavor to discharge. Adjust according to whether the qi coincides or diverges, using more or less accordingly: where it coincides with the heavenly qi, use cold- and coolness-natured transformation; where it coincides with the earthly qi, use warmth- and heat-natured transformation. When employing hot remedies avoid hot seasons; when employing cool remedies avoid cool seasons; when employing warm remedies avoid warm seasons; when employing cold remedies avoid cold seasons — diet should follow the same rule. Where there is a false [semblance], act contrary to this — such is the Way. To act contrary to this principle brings on disease.

The Emperor said: Good. What is the governance of reverting yin [as controller of heaven]? Qibo replied: This is the chronicle of the si and hai years [the snake and pig earthly branches].

Reverting yin governs heaven, with lesser wood as the central movement and lesser yang governing earth; coolness and heat, ascendancy and revenge, follow the same pattern, equivalent to an unmodified great-wood year. Both the dingsi and dinghai years are heaven-conjunction years; the movement progresses from wind to coolness to heat.

Lesser wood, great fire, lesser earth, great metal, lesser water.

Reverting yin governs heaven, with lesser fire as the central movement and lesser yang governing earth; cold and rain, ascendancy and revenge, follow the same pattern. In the guisi and guihai years, the movement progresses from heat to cold to rain.

Lesser fire, great earth, lesser metal, great water, great wood.

Reverting yin governs heaven, with lesser earth as the central movement and lesser yang governing earth; wind and coolness, ascendancy and revenge, follow the same pattern, equivalent to an unmodified great-wood year. In the jisi and jihai years, the movement progresses from rain to wind to coolness.

Lesser earth, great metal, lesser water, lesser wood, great fire.

Reverting yin governs heaven, with lesser metal as the central movement and lesser yang governing earth; heat and cold, ascendancy and revenge, follow the same pattern, equivalent to an unmodified great-wood year. In the yisi and yihai years, the movement progresses from coolness to heat to cold.

Lesser metal, great water, great wood, lesser fire, great earth.

Reverting yin governs heaven, with lesser water as the central movement and lesser yang governing earth; rain and wind, ascendancy and revenge, follow the same pattern. In the xinsi and xinhai years, the movement progresses from cold to rain to wind.

Lesser water, lesser wood, great fire, lesser earth, great metal.

In all years when reverting yin governs heaven in this manner, the transformation and movement of qi run behind the heavenly schedule; but in those years that are equivalent to an unmodified [central movement], the transformation and movement of qi run in step with heaven. The qi of heaven is turbulent while the qi of earth is upright; wind arises from the heights and distances, and blazing heat follows it; clouds hasten toward the chambers of rain, and the transformation of dampness then circulates; wind and fire unite in virtue, corresponding above to the stars Suixing [Jupiter] and Yinghuo [Mars]. Its governance is unsettled and its ordinances swift; its grains are the blue-green and the red; among the supplementary grains, that governed by the greater [movement dominates], and its depleted creatures are the striped-horned and feathered species. Wind, dryness, fire, and heat alternate in ascendancy and revenge; hibernating creatures emerge, and flowing water does not freeze; heat disease circulates below, wind disease circulates above, and the ascendancy and revenge of wind and dryness take shape within. In the first qi, cold begins to turn stern and killing qi is about to arrive; the people suffer cold below on the right side. In the second qi, cold does not depart; snow blossoms and ice forms on the water, killing qi exerts its transformation and frost descends, so that fragrant plants scorch at their tips; cold rain arrives repeatedly, yang returns to transform, and the people suffer heat within. In the third qi, the governance of heaven is displayed, wind arises from time to time, and the people suffer weeping, ringing in the ears, dizziness, and tremor. In the fourth qi, sultry heat and damp-heat contend with one another above on the left side; the people suffer jaundice and puffy swelling. In the fifth qi, dryness and dampness alternate in dominance, deep overcast spreads, cold qi reaches the body, and wind and rain circulate. In the final qi, the dreaded fire [of the interim] takes command, yang undergoes great transformation, hibernating creatures emerge, flowing water does not freeze, the qi of earth bursts forth abundantly, plants grow, and people are at ease, though pestilential warm disease may occur. One must break the stagnant qi, draw upon the source of transformation, and assist the movement-qi, so as not to let evil qi prevail. In such years the acrid flavor should be used to regulate the upper [body] and the salty flavor to regulate the lower; one must not rashly violate the dreaded fire qi. When employing warm remedies avoid warm seasons; when employing hot remedies avoid hot seasons; when employing cool remedies avoid cool seasons; when employing cold remedies avoid cold seasons — diet should follow the same rule. Where there is a false [semblance] contrary to the norm, such is the Way; to act contrary to this brings disease.

The Emperor said: Good. Master's words may be called complete indeed. Yet how are their manifestations to be discerned? Qibo said: How illuminating is this question! The six qi proceed in sequence and rest in [fixed] positions; therefore one customarily observes them at dawn on the first day of the first month, and by observing their position one may know where they are. When a movement is in excess, its arrival comes early; when a movement is insufficient, its arrival comes late — this is the Way of heaven, the constancy of qi. When a movement is neither excessive nor insufficient, this is called a proper year, and its arrival coincides exactly with its due time. The Emperor asked: The qi of ascendancy and revenge is ever-present, yet calamities and portents arrive only at certain times — how is this? Qibo said: What does not accord with the [expected] transformation of qi is called a calamity.

The Emperor asked: How do the numbers of heaven and earth begin and end? Qibo said: How thorough is this question! This is to clarify the Way indeed. The numbering begins above and ends below: before the midpoint of the year, the qi of heaven governs; after the midpoint of the year, the qi of earth governs; where upper and lower intersect, the qi-intersection governs — and thus the chronicle of the year is complete. Hence it is said: once the position is clear, may the month of the qi be known? This is what is meant by 'qi.'

The Emperor asked: I have taken charge of this matter and applied it accordingly, yet it does not always accord with these numbers — why is this? Qibo said: The application of qi has its greater or lesser degree, and the harmony of transformation has its flourishing or decline; whether declining or flourishing, greater or lesser, [these years] nonetheless share the same transformation. The Emperor said: I wish to hear of what is meant by 'sharing the same transformation.' Qibo said: Wind and warmth share the transformation of spring; heat, sultriness, and gloom share the transformation of summer fire, whether as ascendancy or as revenge; dryness, coolness, mist, and dew share the transformation of autumn; clouds, rain, dimness, and dust share the transformation of late summer; cold qi, frost, snow, and ice share the transformation of winter — these are the constant transformations of the five movements and six qi of heaven and earth, alternating in application according to flourishing and decline. The Emperor said: When the five movements coincide with heaven's transformation, this is called a heaven-conjunction [tianfu] year — this I already know. I wish to hear of what is meant by coinciding with earth's transformation. Qibo said: There are three years in which excess coincides with heaven's transformation, and likewise three in which insufficiency coincides with heaven's transformation; there are three years in which excess coincides with earth's transformation, and likewise three in which insufficiency coincides with earth's transformation — twenty-four years in all. The Emperor said: I wish to hear what these are. Qibo said: In the jiachen and jiaxu years, great earth [as central movement] has greater yin added below; in the renyin and renshen years, great wood has reverting yin added below; in the gengzi and gengwu years, great metal has yang brightness added below — these are three. In the guisi and guihai years, lesser fire has lesser yang added below; in the xinchou and xinwei years, lesser water has greater yang added below; in the guimao and guiyou years, lesser fire has lesser yin added below — these are three [more]. In the wuzi and wuwu years, great fire has lesser yin presiding above; in the wuyin and wushen years, great fire has lesser yang presiding above; in the bingchen and bingxu years, great water has greater yang presiding above — these are three. In the dingsi and dinghai years, lesser wood has reverting yin presiding above; in the yimao and yiyou years, lesser metal has yang brightness presiding above; in the jichou and jiwei years, lesser earth has greater yin presiding above — these are three [more]. Apart from these twenty-four years, there is neither 'adding' nor 'presiding.' The Emperor asked: What is meant by 'adding'? Qibo said: When excess is 'added,' this is the same as a heaven-conjunction year; when insufficiency is 'added,' this is the same as a year-conjunction year. The Emperor asked: What is meant by 'presiding'? Qibo said: Whether excess or insufficiency, [when the central movement coincides with the qi governing heaven] both are called heaven-conjunction years, though the degree of change and movement differs, the manifestations of disease vary in severity, and the timing of life and death comes early or late accordingly.

The Emperor said: Master has spoken of employing hot remedies while avoiding heat, and employing cold remedies while avoiding cold — I do not yet understand this; I wish to hear what is meant by 'avoiding.' Qibo said: [In seasons of] heat, do not violate [the principle of avoiding] heat; [in seasons of] cold, do not violate [the principle of avoiding] cold. To follow this brings harmony; to go against it brings disease. One must respectfully hold this in awe and avoid transgressing it — this is what is meant by the seasonal ascendancy of the six positions. The Emperor asked: What of warmth and coolness? Qibo said: When the governing qi is hot, do not violate it by using heat; when the governing qi is cold, do not violate it by using cold; when the governing qi is cool, do not violate it by using coolness; when the governing qi is warm, do not violate it by using warmth. When the interim qi accords with its ruling [seasonal] qi, do not violate it either; when it diverges from its ruling qi, one may violate it slightly — these are called the four things to be held in awe, and one must examine them carefully. The Emperor said: Good. What of when violation is permissible? Qibo said: When the qi of heaven runs contrary to the season, one may rely on the [ordinary] rule; when [the pathogenic qi] overcomes its ruling [seasonal] qi, one may violate [the principle of avoidance], taking balance as the goal, without going to excess — this applies to cases where evil qi has reversed and become dominant. Hence it is said: do not forsake the good faith of heaven, do not go against the fitness of qi, do not assist what is already ascendant, and do not aid what is already in revenge — this is called the perfection of governance.

The Emperor said: Good. Do the movements of the five phases governing the years have a constant numerical order? Qibo said: Allow your servant to set them forth in sequence.

In all these fixed-period chronicles, the ascendancy-and-revenge and the proper transformations each have their constant numbers, which must not go unexamined. Thus one who knows the essential can sum it up in a single phrase; one who does not know the essential wanders in endless dispersion — this is what is meant.

The Emperor said: Good. Do the qi of the five movements also have their revenge upon the year? Qibo said: When stagnation reaches its extreme, it then breaks forth, awaiting its proper time to act. The Emperor said: May I ask what this means? Qibo said: Among the qi of the five constants, excess and insufficiency each break forth differently. The Emperor said: I wish to hear this in full. Qibo said: What is excessive breaks forth violently, what is insufficient breaks forth slowly; the violent produces severe disease, the slow produces lingering disease. The Emperor asked: What of the numbers of excess and insufficiency? Qibo said: The excessive follow the 'completion' numbers, the insufficient follow the 'generation' numbers — earth constantly follows the generation number.

The Emperor asked: What are these outbursts like? Qibo said: When earth's stagnation breaks forth, cliffs and valleys are shaken with fright, thunder rumbles through the qi-intersection, dust darkens [the sky] with yellow and black, transforming into white vapor; sudden squalls sweep the heights and depths, striking rocks and hurling them through the air; floodwaters then rush forth, streams overflow and spread widely, and the fields and pastures become mired in earth. The transforming qi then spreads abroad, becoming favorable seasonal rain, so that growth begins, maturation begins, transformation begins, and completion begins. Thus the people suffer distention of the heart and abdomen, intestinal rumbling with frequent loose stools, and in severe cases heart pain, distention of the ribsides, vomiting, sudden turmoil disorder, fluid effusion with pouring discharge, puffy swelling, and heaviness of the body. Clouds race toward the chambers of rain, rosy clouds encircle the rising sun, and mountains and marshes darken with dust. This outburst occurs during the fourth [seasonal] qi [of the year]. When clouds stretch across the mountains of heaven, drifting and forming and dissolving, this is the first sign of impending stagnation-outburst. When metal's stagnation breaks forth, the heavens are clear and the earth is bright; wind is crisp and the qi is cutting; great coolness then arises; grasses and trees seem wrapped in floating mist, and dry qi circulates; dense fog rises repeatedly, killing qi arrives, plants and trees turn ashen and wither, and metal produces its [characteristic] sound. Thus the people suffer coughing counterflow, fullness of the heart and ribsides drawing into sudden pain in the lesser abdomen so severe that they cannot turn from side to side, dry throat, and a dusty, sickly complexion. Marshes emerge scorched and withered, and the earth congeals with frost and salt-crust. This stagnation-outburst occurs during the fifth [seasonal] qi. When night dew falls white and the forests and thickets sound mournful, this is the sign of impending stagnation-outburst. When water's stagnation breaks forth, yang qi is driven back and yin qi suddenly rises; great cold then arrives, streams and marshes freeze solid, and cold vapor congeals into frost and snow; in severe cases yellow-black haze obscures [the sky], circulating through the qi-intersection, and frost then kills [vegetation] — water thus manifests its portent. Thus the people suffer heart pain from invading cold, pain of the lower back and buttocks, dysfunction of the major joints, difficulty in bending and stretching, tendency to reversal [cold limbs], and hard focal distention with abdominal fullness. The light of yang fails to govern, and an empty accumulation of deep overcast, white dust, and darkness ensues before the outburst occurs — this happens around the second [seasonal] qi, before or after the [interposed] fire [qi]. When the great void grows deeply somber, the qi seeming to disperse like scattered hemp, faintly visible yet hidden, its color black tinged with faint yellow, this is the first sign of impending stagnation-outburst. When wood's stagnation breaks forth, the great void darkens with dust, clouds and vapors are thrown into turmoil, and great winds arrive, tearing roofs and snapping trees — wood undergoes its transformation. Thus the people suffer pain in the stomach cavity felt at the region of the heart, extending upward into both ribsides, obstruction of the diaphragm and throat so that food and drink cannot descend, and in severe cases ringing in the ears, dizziness and spinning vision, failure to recognize people, and sudden rigid collapse. When the great void turns blue-gray with dust, sky and mountains merging into one color, or when the qi turns turbid with a yellow-black hue, stagnating like a spread-out cloud that does not yet release rain, the outburst then occurs — its timing is irregular. When long rivers bend the grasses along their banks, tender leaves show their shaded undersides, pines moan on the high mountains, and tigers roar among the cliffs and caves, these are the first signs of impending stagnation-outburst. When fire's stagnation breaks forth, the great void swells with haze and the sun's brightness is obscured; blazing fire circulates and great summer-heat arrives; mountains and marshes seem to burn and scorch, timber oozes resin, great halls seem wreathed in smoke, the earth's surface floats with frost-salt, standing water diminishes, trailing vines and grasses turn scorched yellow, wind spreads confused rumor, and the transformation of dampness is thereby delayed. Thus the people suffer shortness of qi, sores and welling-abscess swelling in the ribsides, abdomen, chest, back, face, head, and four limbs, distention and fullness, sores and rashes, vomiting counterflow, tugging and slackening convulsions, bone pain, movement within the joints, diarrhea with warm malarial disorder, sudden abdominal pain, overflow and spreading of blood, diminished essence-fluids, red eyes, heat in the heart, and in severe cases clouded oppression and vexation, with a tendency to sudden death. When the marked hours draw to their end amid great warmth, sweat moistens the pores; the outburst then occurs during the fourth [seasonal] qi. Movement then returns to stillness, and yang at its extreme reverts to yin, so that the ordinance of dampness then transforms and completes. When blossoms open while water still lies congealed, when mountains and rivers show ice and snow even as the blazing sun scorches the noon marshes, these are the first signs of impending stagnation-outburst. There is always a manifest response to stagnation before its outburst comes as recompense; in every case one must observe its extreme point, whereupon the outburst occurs. Wood's outburst has no fixed time, for water follows in the wake of fire. If one carefully awaits its proper time, the [course of] disease can be anticipated; but if the timing is missed and the year runs contrary, the five qi fail to proceed in order, and generation, transformation, gathering, and storage lose their constancy in governance.

The Emperor asked: When water breaks forth there is hail and snow; when earth breaks forth there are sudden squalls; when wood breaks forth there is destruction and breakage; when metal breaks forth there is clear brightness; when fire breaks forth there is sultry gloom — what qi causes these? Qibo said: Qi has its greater and lesser degree, and outbursts have their mild and severe forms; the mild correspond to their own [governing] qi alone, while the severe combine with the qi that they overcome below — by examining that subordinate qi, [the pattern] can be discerned.

The Emperor said: Good. Why do the outbursts of the five qi sometimes fail to occur in their proper position? Qibo said: This is termed a 'deviation.' The Emperor asked: Does this deviation have a fixed number? Qibo said: It is always delayed by thirty-some degrees. The Emperor asked: What of when the qi's arrival comes early or late? Qibo said: When a movement is excessive its arrival comes early; when a movement is insufficient its arrival comes late — this is the constant pattern of observation. The Emperor asked: What of when it arrives exactly on time? Qibo said: When it is neither excessive nor insufficient, its arrival falls exactly on time; anything other than this is an aberration. The Emperor said: Good. What of when qi transforms out of season? Qibo said: The excessive transforms within its own proper time, while the insufficient reverts to [the time of] what overcomes it. The Emperor asked: The qi of the four seasons arrives early or late, high or low, left or right — what is the pattern of this? Qibo said: Its movement may be contrary or compliant, and its arrival may be slow or swift; thus the excessive transforms ahead of the heavenly schedule, while the insufficient transforms behind the heavenly schedule. The Emperor said: I wish to hear of this movement — what does it mean? Qibo said: The qi of spring moves westward, the qi of summer moves northward, the qi of autumn moves eastward, and the qi of winter moves southward. Thus the qi of spring begins below, the qi of autumn begins above, the qi of summer begins in the middle, and the qi of winter begins at the tip [periphery]; the qi of spring begins on the left, the qi of autumn begins on the right, the qi of winter begins behind, and the qi of summer begins in front — this is the constant pattern of the four seasons' proper transformation. Thus in high places the qi of winter constantly prevails, and in low places the qi of spring constantly prevails; one must examine this carefully. The Emperor said: Good.

The Yellow Emperor asked: What are the manifest correspondences of the five movements and six qi, the standard order of the six transformations, and the chronicle of the six changes? Qibo replied: The proper chronicle of the six qi encompasses transformation and change, ascendancy and revenge, application and disease — their manifestations are not uniform; which does the Emperor wish [to hear of]? The Emperor said: I wish to hear all of it. Qibo said: Allow me to set it forth in full. As for where the qi arrives: where reverting yin arrives, there is harmony and calm; where lesser yin arrives, there is warmth; where greater yin arrives, there is dust and sultry damp; where lesser yang arrives, there is blazing summer-heat; where yang brightness arrives, there is clear severity; where greater yang arrives, there is a chill vapor of cold — this is the constant pattern of seasonal transformation.

Where reverting yin arrives, it is the chamber of wind, causing cracks to open. Where lesser yin arrives, it is the chamber of fire, causing unfolding and flourishing. Where greater yin arrives, it is the chamber of rain, causing roundness and fullness. Where lesser yang arrives, it is the chamber of heat, causing outward movement. Where yang brightness arrives, it is the chamber that governs killing, causing the hardening and graying [of autumn]. Where greater yang arrives, it is the chamber of cold, causing return and storage. This is the constant pattern of governing transformation.

Where reverting yin arrives, there is generation, and wind causes swaying. Where lesser yin arrives, there is flourishing, and forms become visible. Where greater yin arrives, there is transformation, and clouds bring rain. Where lesser yang arrives, there is growth, and things become lush and vivid. Where yang brightness arrives, there is gathering-in, and fog and dew appear. Where greater yang arrives, there is storage, and all things become tightly sealed. This is the constant pattern of qi transformation.

Where reverting yin arrives, wind is generated, ending in sternness. Where lesser yin arrives, heat is generated, with cold appearing within. Where greater yin arrives, dampness is generated, ending in pouring rain. Where lesser yang arrives, fire is generated, ending in steaming sultriness. Where yang brightness arrives, dryness is generated, ending in coolness. Where greater yang arrives, cold is generated, with warmth appearing within. This is the constant pattern of virtuous transformation. Where reverting yin arrives, the furred creatures transform [flourish]; where lesser yin arrives, the feathered creatures transform; where greater yin arrives, the bare-skinned creatures transform; where lesser yang arrives, the feathered creatures transform; where yang brightness arrives, the shelled creatures transform; where greater yang arrives, the scaled creatures transform. This is the constant pattern of virtuous transformation.

Where reverting yin arrives, there is the transformation of generation; where lesser yin arrives, there is the transformation of flourishing; where greater yin arrives, there is the transformation of moistening; where lesser yang arrives, there is the transformation of luxuriance; where yang brightness arrives, there is the transformation of hardening; where greater yang arrives, there is the transformation of storage. This is the constant pattern of the spreading of governance.

Where reverting yin arrives, there is whirling, furious [wind], and severe coolness; where lesser yin arrives, there is great warmth alternating with cold; where greater yin arrives, there is thunder, sudden downpour, and fierce wind; where lesser yang arrives, there is whirling wind, scorching blaze, and congealing frost; where yang brightness arrives, there is scattering, falling, and warmth; where greater yang arrives, there is cold snow, ice, hail, and white dust. This is the constant pattern of qi change.

Where reverting yin arrives, there is stirring movement, advancing and following. Where lesser yin arrives, there is lofty brilliance and blazing, and dusky glow. Where greater yin arrives, there is deep overcast, white dust, and gloom. Where lesser yang arrives, there is radiant brightness, rosy clouds, and dusky glow. Where yang brightness arrives, there is smoke and dust, frost, cutting severity, and mournful sighing wind. Where greater yang arrives, there is hardness and firmness, sharp awns, and upright standing [of frost-stiffened plants]. This is the constant pattern of the circulation of ordinances.

Where reverting yin arrives, there is urgency within the abdomen; where lesser yin arrives, there are sores, rashes, and fever; where greater yin arrives, there is accumulated fluid with focal obstruction; where lesser yang arrives, there is sneezing, vomiting, and sores; where yang brightness arrives, there is floating vacuity; where greater yang arrives, there is difficulty in bending and stretching. This is the constant pattern of disease. Where reverting yin arrives, there is pain in the limbs; where lesser yin arrives, there is fright and confusion, aversion to cold, shivering, and delirious raving; where greater yin arrives, there is accumulation and fullness; where lesser yang arrives, there is fright and agitation, dizziness, and sudden illness; where yang brightness arrives, there is disease of the nose, sacrum, groin, thighs, knees, hips, calves, shins, and feet; where greater yang arrives, there is lower back pain. This is the constant pattern of disease. Where reverting yin arrives, there is contracture and twisting; where lesser yin arrives, there is sorrow, wild raving, and nosebleed; where greater yin arrives, there is fullness in the middle, sudden turmoil disorder with vomiting and diarrhea; where lesser yang arrives, there is throat obstruction, ringing in the ears, and retching; where yang brightness arrives, there is chapping and peeling of the skin; where greater yang arrives, there is night sweating and tetany. This is the constant pattern of disease. Where reverting yin arrives, there is rib-side pain with vomiting and diarrhea; where lesser yin arrives, there is [inappropriate] talking and laughing; where greater yin arrives, there is heaviness and puffy swelling; where lesser yang arrives, there is sudden pouring diarrhea, twitching, and sudden death; where yang brightness arrives, there is nasal obstruction and sneezing; where greater yang arrives, there is uncontrolled flux and diarrhea. This is the constant pattern of disease.

In all these twelve changes, virtue answers to virtue, transformation answers to transformation, governance answers to governance, and ordinance answers to ordinance; where the qi is high, [its effect] is high; where the qi is low, [its effect] is low; where the qi is behind, [its effect] is behind; where the qi is in front, [its effect] is in front; where the qi is central, [its effect] is central; where the qi is external, [its effect] is external — this is the constancy of position. Thus when wind prevails there is movement; when heat prevails there is swelling; when dryness prevails there is desiccation; when cold prevails there is floating [edema]; when dampness prevails there is sloppy diarrhea, and in severe cases urinary blockage with puffy swelling — one speaks of these changes according to wherever the qi resides.

The Emperor said: I wish to hear of their application. Qibo said: The application of the six qi each resorts to what it cannot overcome in order to bring about transformation. Thus the rain-transformation of greater yin is applied to greater yang; the cold-transformation of greater yang is applied to lesser yin; the heat-transformation of lesser yin is applied to yang brightness; the dryness-transformation of yang brightness is applied to reverting yin; and the wind-transformation of reverting yin is applied to greater yin — each is named according to where it resides, so that it may be verified. The Emperor asked: What of when [a qi] obtains its own position? Qibo said: When it obtains its own position, this is the constant transformation. The Emperor said: I wish to hear where these positions lie. Qibo said: Once its position is designated and its direction fixed, the month [of its governance] can be known. The Emperor asked: What of the fullness and emptiness of the qi in the six positions? Qibo said: The greater and the lesser differ: the greater arrives slowly and steadily, while the lesser arrives suddenly and passes away quickly. The Emperor asked: What of the fullness and emptiness of the qi of heaven and earth? Qibo said: When the qi of heaven is insufficient, the qi of earth follows it; when the qi of earth is insufficient, the qi of heaven follows it; the movement-qi resides between the two and habitually precedes them. It shuns what it cannot overcome and returns to what harmonizes with it, and disease arises as the movement-qi follows and returns accordingly. Thus when the upper [qi] prevails, the qi of heaven descends downward; when the lower [qi] prevails, the qi of earth shifts upward; the degree of deviation varies with the magnitude — a slight [imbalance] produces a small deviation, a severe one produces a great deviation; when severe, the position itself changes and the qi-intersection shifts, whereupon great changes arise and disease breaks out. The Essential Compendium says: severe [deviation] is reckoned at five parts, slight [deviation] at seven parts — its degree of deviation may thus be discerned. This is what is meant.

The Emperor said: Good. The discourse states that in [seasons of] heat one must not violate [the avoidance of] heat, and in [seasons of] cold one must not violate [the avoidance of] cold; yet I wish [at times] not to avoid cold, and not to avoid heat — how is this [reconciled]? Qibo said: How thorough is this question! In releasing the exterior, one need not avoid heat; in attacking the interior, one need not avoid cold. The Emperor asked: What of violating [these avoidances] when neither releasing nor attacking? Qibo said: Then cold and heat will damage the interior, and the disease will only worsen. The Emperor said: I wish to hear what happens in one who has no disease. Qibo said: In one without disease, [such violation] will generate it; in one who already has disease, it will aggravate it. The Emperor asked: What is meant by 'generate'? Qibo said: If one does not avoid heat, heat will arrive; if one does not avoid cold, cold will arrive. When cold arrives, hardness, obstruction, abdominal fullness, urgent pain, and diarrhea will result. When heat arrives, fever, vomiting and diarrhea, sudden turmoil disorder, welling-abscesses and sores, clouded oppression with pouring discharge, twitching and swelling, retching, nasal obstruction, nosebleed, headache, alteration of the bones and joints, muscle pain, overflow and discharge of blood, and painful urinary blockage will result. The Emperor asked: How is this treated? Qibo said: One must always comply with the season; where violation [of the avoidance] is necessary, treat by overcoming [the excess]. The Yellow Emperor asked: In a pregnant woman, how does one apply toxic medicine? Qibo said: If there is due cause, no harm will come — indeed, no harm will come [to the fetus]. The Emperor said: I wish to hear what is meant by 'due cause.' Qibo said: Where there is a great accumulation or great mass, one may indeed attack it with such medicine, stopping once it has been reduced by more than half; to exceed this brings death. The Emperor said: Good. How does one treat severe stagnation? Qibo said: Wood stagnation should be freely vented; fire stagnation should be released outward; earth stagnation should be purged away; metal stagnation should be drained; water stagnation should be broken down — yet in all cases one must regulate the qi, breaking down what is excessive by means of what it dreads; this is what is called 'draining.' The Emperor asked: What of when there is a false [semblance]? Qibo said: Where the qi presents a false [semblance], there is no prohibition [against contrary treatment] — this refers to cases where the host qi is insufficient and the guest qi has become dominant. The Emperor said: Perfect indeed is the Way of the sage! The regulation of the great transformation and circulation of heaven and earth, the chronicle of their presiding governance, the administration of yin and yang, and the ordinances of cold and heat — who but master could master these? I beg to store this away in the Chamber of the Numinous Orchid, entitling it 'The Correct Chronicle of the Six Origins.' Without fasting and purification I dare not display it — let it be transmitted with the utmost care.
