歧伯曰：上下之位，氣交之中，人之居也。故曰：天樞之上，天氣主之；天樞之下，地氣主之。氣交之分，人氣從之，萬物由之。此之謂也。
歧伯曰：上下之位，气交之中，人之居也。故曰：天枢之上，天气主之；天枢之下，地气主之。气交之分，人气从之，万物由之。此之谓也。

Qi Bo said: between the positions above and below, in the midst of the meeting of the qi, is where the human being dwells. Hence it is said: above the heavenly pivot, the qi of heaven governs; below the heavenly pivot, the qi of earth governs. In the region where the qi meet, the qi of the human follows and the ten thousand things go by it. This is what that means.

帝曰：善。所謂精光之論，大聖之業，宣明大道，通於無窮，究於無極也。余聞之，善言天者，必應於人；善言古者，必驗於今；善言氣者，必彰於物；善言應者，同天地之化；善言化言變者，通神明之理。非夫子孰能言至道歟？乃擇良兆而藏之靈室，每旦讀之，命曰氣交變，非齊戒不敢發，慎傳也。

Huang Di said: good. This is what is called the discourse of essential light, the work of the great sage: it proclaims and makes bright the great way, reaching into the endless and fathoming the boundless. I have heard it said that he who speaks well of heaven must find its answer in the human being; he who speaks well of antiquity must find its proof in the present; he who speaks well of the qi must find it displayed in things; he who speaks well of answering is at one with the transformation of heaven and earth; he who speaks well of transformation and of change penetrates the pattern of spirit brightness. Who but you, master, could speak the utmost way? So I have chosen a good omen and laid it away in the chamber of the spirit, reading it every morning; it is named the Meeting of the Qi and Change. Without fasting and purification I dare not open it — hand it on with care.

夏三月，此謂蕃秀。天地氣交，萬物華實。夜卧早起，無厭於日，使志無怒，使華英成秀，使氣得泄，若所愛在外。此夏氣之應，養長之道也。逆之則傷心，秋爲痎瘧，奉收者少，冬至重病。

The three months of summer are called flourishing and fair. The qi of heaven and earth intermingle; the ten thousand things flower and set fruit. Sleep at night and rise early, do not weary of the sun, keep the will free from anger, let the flowering brilliance come to its bloom, and let the qi find its outlet, as though what one loved were outside. This is the answer to the qi of summer, and it is the way of nourishing growth. Going against it harms the heart; in autumn there is jie malaria, there is little to hand on to what must gather in, and at the winter solstice the illness is grave.

流衍之紀，是謂封藏。寒司物化，天地嚴凝，藏政以布，長令不揚。其化凜，其氣堅，其政謐，其令流注，其動漂泄沃涌，其德凝慘寒雰，其變冰雪霜雹，其榖豆稷，其畜彘牛，其果栗棗，其色黑丹黅，其味鹹苦甘，其象冬，其經足少陰太陽，其藏腎心，其蟲鱗倮，其物濡滿，其病脹。上羽而長，氣不化也。政過則化氣大舉，而埃昏氣交，大雨時降，邪傷腎也。

The era of Spreading Flow is called sealing and storing: cold governs the transformation of beings, heaven and earth are sternly congealed, the governance of storage is laid out, and the command of growth is not raised. Its transformation cold and stern, its qi firm, its governance quiet, its command flowing and pouring, its movement drifting, leaking, watering and welling, its virtue congealed bleakness and cold fog, its change ice, snow, frost and hail, its grain beans and panicled millet, its domestic animal the pig and the ox, its fruit the chestnut and the jujube, its colour black, vermilion and yellow, its flavour salty, bitter and sweet, its image winter, its channels the foot lesser yin and greater yang, its viscera the kidney and heart, its creature the scaly and the naked, its thing moist and full, its illness distension. Where the upper is yu growth cannot transform. If its governance goes too far the qi of transformation is greatly raised, dust darkens and the qi intermixes, great rain falls in its season, and evil injures the kidney.
