运气天时地化同，邪正通人五脏中，五脏受邪生五病，五病能该万病形。热合君火
暑合相，盖以支同十二经，虽分二火原同理，
不无微甚重轻情。
【注】木、火、土、金、水五运之化，不能外乎六气风、热、暑、湿、燥、寒。六气
之化亦不能出乎五行，故运虽有五，气虽有六，而天之气令地之运化皆同也。邪化正化
之气，皆通乎人之五脏之中。正化养人，邢化病患。五脏受邪，则生五脏之病。五病能
该万病情形，谓主客一定之病，主客错杂之病，及胜复郁病，皆莫能逃乎五病之变。犹
夫天地化生万物，皆莫能逃乎五行之属也。五行惟火有二，在地为火，在天为热、为暑。以
热合少阴为君火，暑合少阳为相火。盖以地有阴阳十二支，同乎人之阴阳十二经，火虽
有二，理则一也。故其德、政、令、化、灾、病皆同。然不无热微病轻、暑甚病重之情状也。
五星岁木荧惑火，辰水镇土太白金，不及减常之一二，无所不胜色停匀，太过北越
倍一二，畏星失色兼母云，盛衰徐疾征顺逆，留守多少吉凶分。
【注】天之垂象，莫先乎五星。五星者，木、火、土、金、水之五星也。木曰岁星，居
东方。火曰荧惑星，居南方。水曰辰星，居北方。土曰镇星，居西南。金曰太白星，居
西方。其主岁之星，不大不小，不芒不暗，不疾不徐，行所行道，守所守度，此其常也。若
五阴年是为不及，其星则减常之一。不及之甚，则减常之二，其光芒缩。主岁之星，其
色兼我所不胜之色而见也。如木不及，岁星青兼白色也；火不及，荧惑星红兼黑色也；土
不及，镇星黄兼青色也；金不及，太白星白兼红色也；水不及，辰星黑兼黄色也。五阳
年是为太过，其主岁之星北越，谓越出本度而近于北也。北乃紫微之位，太乙所居之宫
也。故倍常之一，太过之甚，倍常之二，其光芒盈。主岁之星，其色纯正，畏我之星，失
其本色，而兼生我之母色也。假如木太过，畏木之星、土星也，失其本色之黄，而兼生土
之火赤色也。盖以木盛而土畏，必盗母气为助，故兼母色见也。土兼赤色，土又生子，余
星仿此。凡星当其时则当盛，非其时则当衰，星迟于天为顺，为灾病轻。星速于天为逆，为
灾病重。稽留不进，守度日多，则灾病重。稽留不进，守度日少，则灾病轻。故曰吉凶分也。
运气、天时与地化是相同的，邪气与正气都贯通于人的五脏之中，五脏受到邪气侵袭便产生五种疾病，这五种疾病能够概括万种病证的形态。热对应君火，暑对应相火，这是因为地支与十二经脉相同，虽然分为两种火，但原初的道理是一样的，只是没有轻重程度的细微差别罢了。
【注】木、火、土、金、水五运的化生作用，不能超出风、热、暑、湿、燥、寒六气的范围。六气的化生作用也不能脱离五行，所以运虽然有五种，气虽然有六种，但天的气令与地的运化都是相同的。邪化与正化的气，都通贯于人的五脏之中。正化滋养人体，邪化导致疾病。五脏受到邪气，就产生五脏的疾病。五种疾病能够概括万种病情，指的是主气与客气固定的病证，主气与客气错杂的病证，以及胜复郁滞的病证，都不能逃脱这五种疾病的演变。就像天地化生万物，都不能逃脱五行的归属一样。五行中唯独火有两种，在地为火，在天为热、为暑。将热归属于少阴作为君火，将暑归属于少阳作为相火。这是因为地有阴阳十二支，与人体的阴阳十二经相同，火虽然有两种，道理却是一致的。所以它们的德、政、令、化、灾、病都是相同的。然而并没有热微病轻、暑甚病重的情状区别。
五星中的岁星属木，荧惑星属火，辰星属水，镇星属土，太白星属金。不及之年减少常数的十分之一或二分之一，无所不胜之色均匀呈现；太过之年向北超越常数的倍一或倍二，畏星失色并伴有母云，盛衰快慢征验顺逆，留守时间的多少区分吉凶。
【注】上天垂示的天象，没有比五星更先显现的。五星就是木、火、土、金、水五星。木称为岁星，居于东方。火称为荧惑星，居于南方。水称为辰星，居于北方。土称为镇星，居于西南。金称为太白星，居于西方。主管年份的星星，不大不小，不芒不暗，不快不慢，行走所应走的轨道，坚守所应守的度数，这是常态。如果是五个阴年，称为不及，其星则减少常数的十分之一。不及得很严重，则减少常数的二分之一，光芒收缩。主管年份的星星，其颜色兼见我所不胜的颜色而显现。如木不及，岁星青色兼白色；火不及，荧惑星红色兼黑色；土不及，镇星黄色兼青色；金不及，太白星白色兼红色；水不及，辰星黑色兼黄色。五个阳年称为太过，其主管年份的星星向北越出，谓越出本度而靠近北方。北方是紫微之位，太乙所居之宫。所以倍于常数的十分之一，太过得很严重，倍于常数的二分之一，光芒充盈。主管年份的星星，其颜色纯正，畏惧我的星星，失去本色，而兼见生我之母色。假如木太过，畏惧木的星星是土星，失去其本色的黄色，而兼见生土的火的赤色。因为木盛而土畏，必定盗取母气作为帮助，所以兼见母色显现。土兼见赤色，土又生子，其余星星仿照此理。凡是星星当令时应当旺盛，不当令时应当衰退，星星迟于天体运行称为顺，灾病轻。星星速于天体运行称为逆，灾病重。稽留不进，守度日子多，则灾病重。稽留不进，守度日子少，则灾病轻。所以说吉凶由此区分。
Yunqi (Five Movements and Six Qi), Tian Shi (Heavenly Timing), and Di Hua (Earthly Transformation) are identical; pathogenic and righteous factors both penetrate the Five Zang Organs. When the Five Zang Organs are affected by pathogens, five types of diseases arise; these five diseases can encompass the manifestations of ten thousand diseases. Heat corresponds to Jun Huo (Monarch Fire), and Summerheat corresponds to Xiang Huo (Ministerial Fire). This is because the Earthly Branches correspond to the Twelve Meridians. Although divided into two types of Fire, their underlying principle is the same, differing only in subtle degrees of severity.
[Note] The transformations of the Five Yun (Wood, Fire, Earth, Metal, Water) cannot exist outside the scope of the Six Qi (Wind, Heat, Summerheat, Dampness, Dryness, Cold). Conversely, the transformations of the Six Qi cannot depart from the Five Elements. Thus, although there are five Yun and six Qi, the Heavenly Qi commands and Earthly Yun transformations are consistent. The Qi of Zheng Hua (Righteous Transformation) and Xie Hua (Pathogenic Transformation) both permeate the human Five Zang Organs. Zheng Hua nourishes the body, while Xie Hua causes illness. When the Five Zang Organs receive pathogens, diseases of the Five Zang Organs arise. The "five diseases" refer to the ability to encompass all pathological conditions, including fixed patterns of Zhu Ke (Host and Guest Qi), mixed patterns of Zhu Ke, and disorders of Sheng Fu (Overcoming and Repression) and Yu Bing (Stagnation). None can escape the variations of these five diseases, just as all things generated by Heaven and Earth fall under the category of the Five Elements. Among the Five Elements, Fire is unique in having two aspects: on Earth it is Fire, in Heaven it is Heat and Summerheat. Heat is associated with Shao Yin (Lesser Yin) as Jun Huo (Monarch Fire), and Summerheat is associated with Shao Yang (Lesser Yang) as Xiang Huo (Ministerial Fire). This is because the Yin-Yang Twelve Earthly Branches correspond to the Yin-Yang Twelve Meridians in the human body. Although Fire has two forms, its principle is one. Therefore, its Virtue (De), Administration (Zheng), Command (Ling), Transformation (Hua), Disaster (Zai), and Disease (Bing) are the same. However, there are distinctions in clinical presentation where mild Heat leads to light disease, and severe Summerheat leads to heavy disease.
The Star Sui (Jupiter) belongs to Wood, Yinghuo (Mars) to Fire, Chenxing (Mercury) to Water, Zhenxing (Saturn) to Earth, and Taibai (Venus) to Metal. In years of Bu Ji (Insufficiency), the star's brightness decreases by one-tenth or one-half of normal, and the color of the element that overcomes it appears evenly. In years of Tai Guo (Excess), the star moves northward beyond its normal degree by one or two times the excess, the Wei Xing (Star of Fear) loses its color and is accompanied by clouds of the generating element. The speed and duration of the star's movement indicate auspiciousness or inauspiciousness based on whether it follows or opposes celestial motion.
[Note] Among heavenly phenomena, none precede the Five Planets (Wu Xing). These are the planets of Wood, Fire, Earth, Metal, and Water. Wood is called Sui Xing (Jupiter), residing in the East. Fire is called Yinghuo Xing (Mars), residing in the South. Water is called Chen Xing (Mercury), residing in the North. Earth is called Zhen Xing (Saturn), residing in the Southwest. Metal is called Taibai Xing (Venus), residing in the West. The star governing the year should be neither too large nor too small, neither too bright nor too dim, neither too fast nor too slow, moving along its proper path and maintaining its proper degree; this is the norm. If it is a Yin year, it is termed Bu Ji (Insufficiency); the star diminishes by one-tenth of normal. If insufficiency is severe, it diminishes by one-half, and its light shrinks. The governing star displays the color of the element that overcomes it. For example, if Wood is insufficient, Sui Xing shows Green mixed with White; if Fire is insufficient, Yinghuo Xing shows Red mixed with Black; if Earth is insufficient, Zhen Xing shows Yellow mixed with Green; if Metal is insufficient, Taibai Xing shows White mixed with Red; if Water is insufficient, Chen Xing shows Black mixed with Yellow. If it is a Yang year, it is termed Tai Guo (Excess); the governing star moves northward, meaning it deviates from its degree toward the North. The North is the position of Ziwei (Purple Tenuity), the palace of Taiyi. Thus, exceeding by one-tenth indicates slight excess; exceeding by one-half indicates severe excess, and its light is full. The governing star's color is pure, while the star that fears it loses its original color and assumes the color of its mother (generating element). For instance, if Wood is excessive, the star fearing Wood is Earth (Zhen Xing); it loses its yellow color and assumes the red color of Fire (which generates Earth). This is because when Wood is prosperous, Earth fears it and must borrow Qi from its mother (Fire) for support, hence displaying the mother's color. Earth showing red implies Earth generates Metal, and other stars follow this logic. Generally, a star is prosperous when in season and waning when out of season. A star moving slower than the heavens is considered Shun (Smooth/Auspicious), indicating light disaster or disease. A star moving faster than the heavens is considered Ni (Rebellious/Inauspicious), indicating heavy disaster or disease. If a star lingers and does not advance, staying at a degree for many days, the disaster or disease is heavy. If it lingers but stays for few days, the disaster or disease is light. Thus, auspiciousness and inauspiciousness are distinguished.
