黄帝内经·素问
Overall Paraphrased Meaning
The "Great Treatise on Regulation of Spirit According to the Four Qi" discusses how humans should attune their spirit and physical form to the qi of spring, summer, autumn, and winter. Its core principle is "correspondence between heaven and humanity" — the rhythm of human life moves in synchrony with heaven and earth.
The three months of Spring (first through third months) are called "Fachen" — pushing out the old and bringing forth the new. The qi of heaven and earth bursts forth with vitality, and the myriad things flourish. People should sleep late and rise early, take leisurely long walks in the courtyard, let down their hair and loosen their garments, allowing the body to stretch and the mind to unfold with it. Toward life, one should "give life without killing, bestow without taking away, reward without punishing" — nurture more, give more, encourage more; kill less, deprive less, punish less. This is the way of obeying the qi of spring and nourishing "birth." Violating this harms the liver, and come summer one will suffer cold-type disorders, because the energy supplied for summer "growth" will be insufficient.
The three months of Summer (fourth through sixth months) are called "Fanxiu" — luxuriant and flourishing. The qi of heaven and earth intermingle, and the myriad things blossom and bear fruit. People should sleep late and rise early, not grow weary of the long daylight, allowing the mind to be free of anger, letting the radiance of life blossom fully, and permitting the qi to vent outward, as if something beloved were drawing you forth. This is the way of obeying the qi of summer and nourishing "growth." Violating this harms the heart, and come autumn one will suffer malaria, for the energy supplied for autumn "harvest" will be insufficient; in winter, serious illness may recur.
The three months of Autumn (seventh through ninth months) are called "Rongping" — when the myriad things ripen and their forms settle. The qi of heaven turns urgent and sharp; the qi of earth turns clear and bright. People should sleep early and rise early, getting up at cockcrow, letting the mind be peaceful to soften autumn's killing air; gathering the spirit inward so that autumn qi can be harmonious; not letting the mind race outward, so that the qi of the lungs remains clear and pure. This is the way of obeying the qi of autumn and nourishing "harvest." Violating this harms the lungs, and come winter one will suffer sunset diarrhea (undigested food in the stool), for the energy supplied for winter "storage" will be insufficient.
The three months of Winter (tenth through twelfth months) are called "Bicang" — closure and concealment, when the myriad things go into hiding and vitality withdraws inward. Water freezes and earth cracks; do not disturb the yang qi within. People should sleep early and rise late, waiting until the sun has risen before getting up; let the mind be as if in ambush, as if hidden away, like keeping a private matter secret, like having obtained something and being content; avoid cold and seek warmth, and do not let the skin open excessively and sweat, lest yang qi be repeatedly drained away. This is the way of obeying the qi of winter and nourishing "storage." Violating this harms the kidneys, and come spring one will suffer wei-jue (limpness and weakness of the limbs with cold extremities), for the energy supplied for spring "birth" will be insufficient.
Next, the treatise speaks of the way of heaven and earth. The qi of heaven is clear and luminous, bearing within it the "virtue" of ceaseless motion, and therefore it remains forever bright without falling. If the qi of heaven becomes turbid and dim, the sun and moon lose their radiance, and pernicious qi assails the orifices; yang qi becomes blocked, the qi of earth grows obscure and murky, clouds and mists spread without dispersing, and white dew does not descend. When the qi of heaven and earth can no longer communicate, the life of the myriad things cannot continue, and even great trees wither and die. When malignant turbid qi cannot dissipate, wind and rain fall out of harmony, white dew does not descend, and grasses and trees wither and drop away. When thieves' winds blow frequently and violent rains pour down repeatedly, heaven and earth's four seasons lose their proper order, deviating from the root way, and the myriad things perish prematurely.
The Sage (one who has penetrated the Way) follows these patterns, and so the body incurs no strange illnesses, the myriad things do not lose their essential nature, and vitality is never exhausted. Violating the qi of spring, Shaoyang (the nascent yang of spring) cannot emerge, and the qi of the liver becomes congested and illness arises; violating the qi of summer, Taiyang (the exuberant yang of summer) cannot grow, and the qi of the heart becomes empty within; violating the qi of autumn, Taiyin (the gathering yin of autumn) cannot harvest, and the qi of the lungs becomes scorched, dry, and distended; violating the qi of winter, Shaoyin (the storing yin of winter) cannot conceal, and the qi of the kidneys withers and suffers isolated decline.
The four seasons and their yin-yang are the root of the myriad things. Therefore the sages nourish yang in spring and summer, and nourish yin in autumn and winter, precisely in order to follow the root — and thus they can rise and sink together with the myriad things within the cycles of birth, growth, harvest, and storage. To violate this root is to cut down one's own foundation of life and destroy the true essence of one's being.
Thus yin-yang and the four seasons are the beginning and end of the myriad things, the root of death and life. To violate them brings disaster upon disaster; to obey them keeps one free of grave illness — this is called "attaining the Way." The Way: the sage practices it earnestly, while the foolish only pay it lip service. To obey yin-yang is to live; to violate it is to die. To obey it is to be at peace; to violate it is to fall into chaos. To turn what is obedient into the perverse is called "neige" — the inner environment of qi and blood standing at odds with heaven and earth.
Therefore the sage does not treat an illness already manifest, but regulates the body before illness arises; does not govern disorder already formed, but orders things before chaos ensues. To take medicine only after illness has developed, to govern only after trouble has erupted, is like digging a well only when thirsty, or casting weapons only when war has broken out — is this not too late?
The core thesis of this chapter can be formulated as three layers of progressive reasoning:
First layer: Seasonal cultivation — aligning the rhythm of life with nature. The "four qi" are spring warmth, summer heat, autumn coolness, and winter cold. "Regulating the spirit" means adjusting one's mental activity and daily routines accordingly. Each season carries specific prescriptions for rest, mentality, and behavior, grounded in the visceral manifestation theory (zang-xiang): spring → liver → birth, summer → heart → growth, autumn → lungs → harvest, winter → kidneys → storage. This is one of the most systematic expressions of the Chinese medical principle of "correspondence between heaven and humanity."
Second layer: The mutual rooting of yin and yang — "nourish yang in spring and summer, nourish yin in autumn and winter." In spring and summer, yang qi moves outward; one nourishes yang (aiding its emergence and growth). In autumn and winter, yin qi gathers inward; one nourishes yin (aiding its harvest and storage). This is not simply "warm-nourish in heat, cold-nourish in cold," but rather aligning human yin-yang with the direction of the seasons, maintaining synchrony with heaven and earth, so that one may "rise and sink with the myriad things at the gate of growth and storage."
Third layer: Treating what has not yet arisen — prevention as the supreme principle. The closing passage — "the sage does not treat the already-ill, but treats what is not yet ill" — is one of the most influential propositions in the entire Huangdi Neijing. It shifts the focus of medicine from "treating disease" forward to "preventing disease," forward to the domain of daily living itself. This is the wellspring of Chinese medicine's philosophy of preventive medicine.
The three layers are logically cohesive: following the four seasons (concrete methods) → obeying the root of yin-yang (principle) → achieving treatment-before-illness (ultimate aim).
