帝曰∶寒暑燥湿风火，在人合之奈何？其于万物何以生化？岐伯曰∶东方生风，风生木。其在天为玄，在人为道，
在地为化。化生五味，道生智，玄生神，化生气。神在天为风，在地为木。其性为暄，其德为和，其用为动，其色为苍，
其化为荣，其虫毛，其政为散，其令宣发，其变摧拉，其眚为陨。南方生热，热生火。中央生湿，湿生土。西方生燥，
燥生金。北方生寒，寒生水。五气更立，各有所先，非其位则邪，当其位则正。帝曰∶病之生变何如？岐伯曰∶气相得
则微，不相得则甚。帝曰∶主岁何如？岐伯曰∶气有余，则制己所胜而侮所不胜；其不及，则己所不胜侮而乘之，己所
胜轻而侮之。侮反受邪，侮而受邪，寡于畏也。帝曰∶善。（见藏象类六。）
天运当以日光明。（疾病五。）
天温日明，则人血淖液而卫气浮，故血易泻，气易行；天寒日阴，则人血凝泣而卫气沉。月始生，则血气始精，卫

黄帝问道：寒、暑、燥、湿、风、火六气，在人体是如何对应的？它们对于万物的生化作用是怎样的？岐伯回答说：东方生风，风能生木。在天表现为玄妙，在人体现为道，在地表现为化育。化育产生五味，道产生智慧，玄妙产生神机，化育产生气。神机在天表现为风，在地表现为木。其性质是温暖，其德性是平和，其作用是运动，其颜色是青色，其化育景象是繁荣，其对应的动物是有毛的兽类，其政令是疏散，其命令是宣发，其异常变化是摧折拉断，其灾祸是陨落。南方生热，热能生火。中央生湿，湿能生土。西方生燥，燥能生金。北方生寒，寒能生水。五气轮流主事，各有先后次序，不在其位则为邪气，在其位则为正气。黄帝问：疾病发生的变化是怎样的？岐伯说：运气相得则病轻，不相得则病重。黄帝问：主管岁运的情况如何？岐伯说：气有余，则克制自己所能胜的，并反侮自己不能胜的；气不足，则自己不能胜的来欺凌并乘袭它，自己所能胜的也轻视而反侮它。反侮者反而受邪，是因为缺乏敬畏之心。黄帝说：好。（见藏象类六。）
天体的运行应当以日光的明暗为依据。（疾病五。）
天气温暖且阳光明媚，人的血液稀薄流动，卫气浮越于体表，所以血易泻出，气易运行；天气寒冷且阴暗，人的血液凝滞涩少，卫气沉伏于体内。月亮初生时，人的血气开始精纯，卫气开始运行；月亮圆满时，人的血气充实，肌肉坚实；月亮亏空时，人的肌肉减损，经络空虚，卫气离去，形体独存。因此要根据天时来调治血气。星辰是用来测定日月运行的轨迹的。八正（指二分、二至、四立八个节气）是用来观察八方虚邪之风按时到来的。四季是用来区分春夏秋冬之气所在的不同部位，以便按时进行调理的，要避开八正的虚邪，不要触犯。以人体的虚弱，遇到天时的虚弱，两虚相感，邪气深入至骨，入内则损伤五脏，医生若能及时守候救治，就不会受到损伤，所以说天的禁忌不可不知。（针刺十三。）
必须首先了解当年的岁气，不要破坏天和的自然平衡。（论治十一。）
自然的化育功能不可以人为代替，四时的时序不可以违背。（论治十二。）
各种疾病的邪气，一天之中可以分为四个时段。（疾病二十三。）
阳气在白天主要主持体表的机能，平旦时人气开始生发，日中时阳气最隆盛，日西时阳气已虚，汗孔乃闭合。（疾病五。）
人与天地是相互参合的，与日月是相应的。所以月亮满的时候，海水向西涨盛，人的血气积聚，肌肉充实，皮肤致密，毛发坚挺，腠理紧密，烟垢附着。在这个时候，即使遇到贼风，侵入也很浅不深。到了月亮亏空的时候，海水向东涨盛，人的气血虚弱，卫气离去，形体独存，肌肉减损，皮肤松弛，腠理开泄，毛发残落，腠理变薄，烟垢脱落。在这个时候，遇到贼风则侵入很深，发病也突然猛烈。（运气三十六。）
阴中有阴，阳中有阳。从平旦到日中，是天之阳，属于阳中之阳；从日中到黄昏，是天之阳，属于阳中之阴；从合夜到鸡鸣，是天之阴，属于阴中之阴；从鸡鸣到平旦，是天之阴，属于阴中之阳。所以人也与之相应。（阴阳五。）
日中时阳气隆盛称为重阳，夜半时阴气隆盛称为重阴。夜半是阴气隆盛，夜半过后阴气衰退，平旦时阴气尽而阳气受气。日中是阳气隆盛，日西时阳气衰退，日落时阳气尽而阴气受气。夜半时阴阳大会，万民皆卧睡，叫做合阴。（经络二十三。）
天周有二十八宿，每宿三分。（经络二十六。）
一年有十二月，一日有十二辰，子午经线，卯酉纬线。天周二十八宿，每一面七星，四七共二十八星，房宿和昴宿为纬线，虚宿和张宿为经线。房宿到毕宿为阳，昴宿到尾宿为阴，阳主昼，阴主夜。太阳行经一舍，人气在体内运行一周又十分身之八。（经络二十五。）
春季三个月，叫做发陈，天地俱生，万物繁荣，这是春气的应验，是养生的方法。违背它则伤肝，夏季会发生寒性病变，奉养长夏之气就少了。夏季三个月，叫做蕃秀，天地之气交合，万物开花结果，这是夏气的应验，是养长的方法。违背它则伤心，秋季会发生疟疾，奉养收敛之气就少了，冬至时会重病。秋季三个月，叫做容平，天气以急劲，地气以清明，这是秋气的应验，是养收的方法。违背它则伤肺，冬季会发生完谷不化的泄泻，奉养闭藏之气就少了。冬季三个月，叫做闭藏，水结冰地裂开，不要扰动阳气，这是冬气的应验，是养藏的方法。违背它则伤肾，春季会发生痿厥，奉养生发之气就少了。（摄生四。）
那春天的温暖，成为夏天的暑热；那秋天的肃杀，成为冬天的严寒。春气符合规圆的法则，夏气符合矩方的法则，秋气符合衡平的法则，冬气符合权重的法则。所以冬至后四十五日，阳气微微上升，阴气微微下降；夏至后四十五日，阴气微微上升，阳气微微下降，阴阳有时限，与脉象的周期相应。（脉色九。）
大月小月合计三百六十日构成一岁，人也与之相应。生命因春而生，因夏而长，因秋而收，因冬而藏，失常则天地四塞不通。（经络二十九。）
所谓得到四时相胜的关系，是春胜长夏，长夏胜冬，冬胜夏，夏胜秋，秋胜春，这就是所谓的四时之胜。（疾病类二十七。）
春夏时节阳气多而阴气少，秋冬时节阴气盛而阳气衰。（疾病三十四。）
脏对应冬，色对应春，时令对应夏，音对应长夏，味对应秋。（针刺十七。）
春气在经脉，夏气在孙络，长夏气在肌肉，秋气在皮肤，冬气在骨髓中。黄帝说：我希望听您讲讲其中的缘故。岐伯说：春天，天气开始开放，地气开始泄出，冻解冰释，水流经络通畅，所以人气在脉。夏天，经络满溢，气进入孙络受血，皮肤充实。长夏，经络都盛满，内溢于肌肉之中。秋天，天气开始收敛，腠理闭塞，皮肤收紧。冬天，盖藏封闭，血气在中，内着于骨髓，通达五脏。所以邪气，常随着四时气血的变化而入客，至于其变化，无法用固定的尺度衡量。（针刺十九。）
春气在毫毛，夏气在皮肤，秋气在分肉，冬气在筋骨。（针刺十八。）
正月二月，天气开始方正，人气在肝。三月四月，天气正方，地气定发，人气在脾。五月六月，天气盛大，地气高升，人气在头。七月八月，阴气开始肃杀，人气在肺。九月十月，阴气开始结冰，地气开始闭藏，人气在心。十一月十二月，冰复结，地气合拢，人气在肾。（针刺十九。）
东方地域，是天地开始生长的地方。西方是金玉之地，砂石之处，是天地收敛牵引的地方。北方是天地闭藏的地方。南方是天地所长养、阳气旺盛的地方，地势低下，水土弱，雾露聚集。中央地区，地势平坦而湿润，天地所生万物众多。（论治九。）
身形对应九野。天的禁忌。（经络三十五。）
违背春气，则少阳不生，肝气在内发生变异。违背夏气，则太阳不长，心气在内空虚。违背秋气，则太阴不收，肺气焦枯胀满。违背冬气，则少阴不藏，肾气独自沉陷。四时阴阳，是万物的根本，所以圣人春夏养阳，秋冬养阴，以顺应其根本。（摄生六。）
脾不单独主令一时。（藏象七。）
德、化、政、令、灾、变，不能互相叠加。胜、复、盛、衰，不能互相增多。往来大小，不能互相超过。用的升降，不能互相没有。只是各自跟随其运动而回复罢了。（运气十二。）
有胜气则有复气，无胜气则无复气。胜气到来则有复气，没有固定的次数，等到衰弱才停止。复气结束而胜气又来，不复气则有害，这是伤害生命。（运气二十九。）
乘着危险而行，不速而至，炎威无德，灾祸反而及身，轻微的胜气导致轻微的复气，严重的胜气导致严重的复气。（运气十三。）
阴阳，就是寒暑。热则雨水滋润在上，根部缺少汁液，人气在外，皮肤松弛，腠理开泄，血气减少，大汗淋漓，皮肤润泽。寒则地冻水冰，人气在中，皮肤致密，腠理闭合，不出汗，血气强盛，肌肉坚硬涩滞。（针刺三十五。）
治疗王气，反而会出错。（论治七。）
所以使用针法的人，如果不了解年之所加，气之盛衰，虚实之所起，就不能成为好的医生。（针刺六。）
Yellow Emperor asked: How do the six Qi of Cold, Heat, Dryness, Dampness, Wind, and Fire correspond to the human body? What is their role in the generation and transformation of all things? Qibo replied: The East generates Wind, and Wind generates Wood. In Heaven it manifests as Mystery (Xuan), in Man it manifests as Dao, and on Earth it manifests as Transformation (Hua). Transformation generates the Five Flavors, Dao generates Wisdom, Mystery generates Spirit (Shen), and Transformation generates Qi. Spirit in Heaven manifests as Wind, and on Earth manifests as Wood. Its nature is warmth, its virtue is harmony, its function is movement, its color is green/cyan, its transformation is flourishing, its associated animals are those with fur, its governance is dispersion, its command is dissemination, its abnormal change is destruction and tearing, and its disaster is falling. The South generates Heat, and Heat generates Fire. The Center generates Dampness, and Dampness generates Earth. The West generates Dryness, and Dryness generates Metal. The North generates Cold, and Cold generates Water. The Five Qi take turns ruling, each having its precedence; if not in its proper position, it becomes pathogenic; if in its proper position, it is normal. Yellow Emperor asked: How do diseases undergo changes? Qibo said: When the Qi are compatible, the disease is mild; when incompatible, it is severe. Yellow Emperor asked: How does the ruling year's Qi behave? Qibo said: If Qi is in excess, it controls what it normally overcomes and insults what it cannot overcome; if Qi is deficient, what it cannot overcome bullies and exploits it, and what it normally overcomes lightly insults it. Those who insult may instead suffer from pathogenic factors because they lack reverence. Yellow Emperor said: Excellent. (See Zang-Xiang Category 6.)
The movement of Heaven should be determined by the brightness of the Sun. (Disease 5.)
When the weather is warm and sunny, human blood becomes fluid and Wei-Qi floats on the surface; thus blood is easily discharged and Qi moves easily. When the weather is cold and cloudy, human blood becomes stagnant and Wei-Qi sinks. When the moon begins to wax, blood and Qi begin to refine, and Wei-Qi begins to circulate; when the moon is full, blood and Qi are substantial, and muscles are firm; when the moon wanes, muscles diminish, meridians become empty, Wei-Qi departs, and only the form remains. Therefore, one must regulate blood and Qi according to heavenly timing. Stars are used to measure the movement of the sun and moon. The Eight Norms (Bafen) are used to observe the deficiency pathogens of the Eight Winds arriving at their proper times. The Four Seasons are used to distinguish where the Qi of Spring, Summer, Autumn, and Winter reside, allowing for timely regulation; one must avoid the deficiency pathogens of the Eight Norms and not offend them. With a weak body encountering weak heaven, two deficiencies interacting, the Qi reaches the bone; entering inward, it damages the Zang organs. If physicians wait and rescue promptly, they cannot be damaged; thus, it is said that Heavenly Taboos must not be unknown. (Acupuncture 13.)
One must first know the annual Qi and not disrupt the natural Harmony of Heaven. (Treatment Discussion 11.)
Natural transformation cannot be replaced by human intervention, and seasonal timing cannot be violated. (Treatment Discussion 12.)
The Qi of various diseases can be divided into four periods within a single day. (Disease 23.)
Yang Qi governs the exterior during the day. At dawn, human Qi begins to generate; at noon, Yang Qi is most vigorous; at sunset, Yang Qi is already deficient, and the pores close. (Disease 5.)
Humans participate in Heaven and Earth and correspond to the Sun and Moon. Thus, when the moon is full, seawater swells toward the west, human blood and Qi accumulate, muscles are full, skin is dense, hair is firm, and interstices are tight, so smoke residue adheres. At this time, even if attacked by treacherous winds, the invasion is shallow. When the moon wanes, seawater swells toward the east, human blood and Qi are deficient, Wei-Qi departs, form remains alone, muscles diminish, skin relaxes, interstices open, hair falls out, interstices become thin, and smoke residue falls off. At this time, encountering treacherous winds leads to deep invasion and sudden, violent illness. (Luck 36.)
Yin contains Yin, and Yang contains Yang. From dawn to noon, it is Heaven's Yang, which is Yang within Yang; from noon to dusk, it is Heaven's Yang, which is Yin within Yang; from nightfall to rooster crow, it is Heaven's Yin, which is Yin within Yin; from rooster crow to dawn, it is Heaven's Yin, which is Yang within Yin. Thus, humans also correspond to this. (Yin-Yang 5.)
At noon, Yang peaks, called Double Yang; at midnight, Yin peaks, called Double Yin. Midnight is Yin peak; after midnight, Yin declines, and at dawn, Yin ends and Yang receives Qi. Noon is Yang peak; sunset is Yang decline; at sunset, Yang ends and Yin receives Qi. At midnight, there is a great convergence, and all people sleep, called Convergence of Yin. (Meridians 23.)
Heaven encompasses 28 Mansions, each divided into 36 parts. (Meridians 26.)
A year has 12 months, a day has 12 double-hours. Zi-Wu forms the meridian line, Mao-You forms the latitude line. Heaven encompasses 28 Mansions, seven stars per side, totaling 28 stars. Fang and Mao form the latitude lines, Xu and Zhang form the meridian lines. From Fang to Bi is Yang, from Mao to Wei is Yin. Yang governs day, Yin governs night. As the sun travels one Mansion, human Qi circulates once plus eight-tenths of the body. (Meridians 25.)
The three months of Spring are called "Revealing the Old." Heaven and Earth grow together, and all things flourish. This is the response to Spring Qi, the way of nourishing life. Violating it injures the Liver, causing cold transformations in Summer, with little left to support growth. The three months of Summer are called "Lush and Beautiful." Heaven and Earth Qi intersect, and all things flower and fruit. This is the response to Summer Qi, the way of nourishing growth. Violating it injures the Heart, causing malaria in Autumn, with little left to support harvesting, leading to severe illness at Winter Solstice. The three months of Autumn are called "Containing and Leveling." Heaven's Qi is urgent, Earth's Qi is clear. This is the response to Autumn Qi, the way of nourishing harvesting. Violating it injures the Lungs, causing undigested diarrhea in Winter, with little left to support storage. The three months of Winter are called "Closing and Storing." Water freezes, earth cracks; do not disturb Yang. This is the response to Winter Qi, the way of nourishing storage. Violating it injures the Kidneys, causing flaccidity and cold limbs in Spring, with little left to support generation. (Preservation 4.)
The warmth of Spring becomes the heat of Summer; the severity of Autumn becomes the anger of Winter. Spring corresponds to the compass circle, Summer to the square ruler, Autumn to the balance beam, Winter to the steelyard weight. Thus, 45 days after Winter Solstice, Yang Qi slightly ascends, Yin Qi slightly descends; 45 days after Summer Solstice, Yin Qi slightly ascends, Yang Qi slightly descends. Yin and Yang have their times, corresponding to the pulse cycle. (Pulse Color 9.)
Large and small months total 360 days to form a year, and humans also correspond. Life arises due to Spring, grows due to Summer, harvests due to Autumn, stores due to Winter. Deviating from this causes Heaven and Earth to be blocked. (Meridians 29.)
What is meant by "overcoming of the Four Seasons" is: Spring overcomes Long Summer, Long Summer overcomes Winter, Winter overcomes Summer, Summer overcomes Autumn, Autumn overcomes Spring. This is called the overcoming of the Four Seasons. (Disease Category 27.)
In Spring and Summer, Yang Qi is abundant and Yin Qi is scarce; in Autumn and Winter, Yin Qi is prosperous and Yang Qi is declining. (Disease 34.)
Zang organs correspond to Winter, colors to Spring, seasons to Summer, tones to Long Summer, flavors to Autumn. (Acupuncture 17.)
Spring Qi resides in the Main Meridians, Summer Qi in the Branch Collaterals, Long Summer Qi in the Muscles, Autumn Qi in the Skin, and Winter Qi in the Bone Marrow. Yellow Emperor said: I wish to hear the reason. Qibo said: In Spring, Heaven's Qi opens, Earth's Qi exudes, ice melts, water flows, and meridians connect, so human Qi is in the vessels. In Summer, vessels are full, Qi overflows, entering branch collaterals to receive blood, making skin substantial. In Long Summer, both meridians and collaterals are prosperous, overflowing internally into muscles. In Autumn, Heaven's Qi gathers, interstices close, skin tightens. In Winter, covering and storing occurs, blood and Qi remain inside, attaching to bone marrow and connecting to the Zang organs. Therefore, pathogenic Qi often enters and lodges following the changes of seasonal blood and Qi; regarding its variations, no fixed measure can be applied. (Acupuncture 19.)
Spring Qi is in the fine hairs, Summer Qi in the skin, Autumn Qi in the muscle layers, Winter Qi in the tendons and bones. (Acupuncture 18.)
First and second lunar months, Heaven's Qi begins to stabilize, human Qi is in the Liver. Third and fourth months, Heaven's Qi is stable, Earth's Qi develops, human Qi is in the Spleen. Fifth and sixth months, Heaven's Qi is abundant, Earth's Qi is high, human Qi is in the head. Seventh and eighth months, Yin Qi begins to kill, human Qi is in the Lungs. Ninth and tenth months, Yin Qi begins to freeze, Earth's Qi closes, human Qi is in the Heart. Eleventh and twelfth months, ice returns, Earth's Qi combines, human Qi is in the Kidneys. (Acupuncture 19.)
The Eastern region is where Heaven and Earth begin to generate. The Western region is land of gold and jade, sand and stone, where Heaven and Earth gather and draw in. The Northern region is where Heaven and Earth store and hide. The Southern region is where Heaven and Earth nurture and raise, where Yang Qi is abundant; the terrain is low, waters and soils are weak, and fog and dew gather. The Central region is flat and damp, where Heaven and Earth produce many things. (Treatment Discussion 9.)
The body shape corresponds to the Nine Fields. Heavenly Taboos. (Meridians 35.)
Violating Spring Qi, Shaoyang does not generate, Liver Qi changes internally. Violating Summer Qi, Taiyang does not grow, Heart Qi becomes hollow internally. Violating Autumn Qi, Taiyin does not collect, Lung Qi becomes dry and full. Violating Winter Qi, Shao Yin does not store, Kidney Qi sinks alone. The Yin and Yang of the Four Seasons are the root of all things; therefore, sages nourish Yang in Spring and Summer, and nourish Yin in Autumn and Winter, to follow their root. (Preservation 6.)
The Spleen does not rule a specific season. (Zang-Xiang 7.)
Virtue, transformation, governance, command, disaster, and change cannot add to each other. Victory, return, prosperity, and decline cannot multiply each other. Coming and going, small and large, cannot exceed each other. Use, ascent and descent, cannot exist without each other. Each follows its movement and returns. (Luck 12.)
Where there is victory, there is return; where there is no victory, there is no return. When victory arrives, return follows; there is no constant number, it stops only when declining. After return ends, victory comes again; if there is no return, harm results, injuring life. (Luck 29.)
Acting upon danger, arriving quickly, heat and might without virtue, disaster returns to them. Minor victories bring minor returns, major victories bring major returns. (Luck 13.)
Yin and Yang are Cold and Heat. Heat brings rain above, roots lack juice, human Qi is outside, skin is relaxed, interstices open, blood and Qi decrease, sweat pours heavily, skin is moist. Cold freezes earth and water, human Qi is inside, skin is dense, interstices close, no sweat, blood and Qi are strong, muscles are hard and astringent. (Acupuncture 35.)
Treating the Wang Qi (Dominant Qi) leads to error. (Treatment Discussion 7.)
Therefore, a practitioner who does not know the annual additions, the rise and fall of Qi, and the origin of deficiency and excess cannot be a skilled physician. (Acupuncture 6.)
