(1)Huangdi asked: Heaven has the Five Phases, controlling the five positions to generate cold, heat, dryness, dampness, and wind. Humans have five organs, transforming five qi, to generate joy, anger, thought, worry, and fear. The discussion says that the Five Evolutive Phases follow one another and all govern them, ending on the final day, cycling and starting anew. I already know this, but I wish to hear how they correspond with the three yin and three yang periods. How do they combine? Guiyuqu bowed twice and replied: What a clear question! The Five Evolutive Phases and yin-yang are the way of heaven and earth, the guiding principles of all things, the parents of change, the origin of life and death, the residence of mental activity. Can one not understand them? Thus, the birth of things is called transformation, the extremity of things is called change, the unpredictability of yin-yang is called spirit (2), the use of spirit without boundaries is called sage. The function of change is, in heaven, mystery; in humans, the way; on earth, transformation. Transformation produces Wuwei, the way produces wisdom, mystery produces spirit. Spirit in heaven is wind, on earth is wood; in heaven is heat, on earth is fire; in heaven is dampness, on earth is soil; in heaven is dryness, on earth is metal; in heaven is cold, on earth is water. Thus, in heaven it is qi, on earth it takes form. Form and qi interact and transform to produce all things. However, heaven and earth are the above and below of all things; left and right are the paths of yin-yang. Water and fire are the signs of yin-yang; metal and wood are the Zhongshi of generation and completion (3). Qi has its quantities, form has its flourishing and decline, above and below summon each other, and thus increase and decrease become clear.
The Emperor said: I wish to hear about the Five Evolutive Phases governing the seasons, how is it? Guiyuqu said: The five qi circulate, each ending its cycle day (4), not just governing the seasons.The Emperor said: Please explain what you mean. Guiyuqu said: I have extensively studied the Taishi Tianyuan Ce text which says: The vast void, beginning the foundation of transformation yuan (5), all things begin here, the Five Evolutive Phases end in heaven, spreading qi true spirit, governing the earth yuan, the nine stars (6) hang bright, the seven luminaries (7) revolve, called yin and yang, called soft and hard (8), the hidden and manifest take their positions, cold and heat stretch and contract, life generation and transformation, all things are clearly manifested. I, for ten generations, this is what is meant.
The Emperor said: Good. What is meant by the varying amounts of qi and the flourishing and decline of forms? Guiyuqu said: The qi of yin and yang each has varying amounts, hence the term three yin and three yang. The flourishing and decline of forms refer to the governance of the Five Phases, each having excess and deficiency. Therefore, at the beginning, when there is excess, deficiency follows; when there is deficiency, excess follows. Knowing how to anticipate and follow, the qi can be predicted. Corresponding to heaven is celestial correspondence, aligning with the year is year alignment, and the combination of the three constitutes governance.
The Emperor asked: How do the upper and lower realms summon each other? Guiyuqu replied: Cold, heat, dryness, dampness, wind, and fire are the yin-yang of heaven, and the three yin and three yang above follow them. Wood, fire, earth, metal, water, and fire are the yin-yang of earth, and growth, transformation, and storage below respond to them. Heaven has yin growing while yang generates, and earth has yin concealing while yang declines. Heaven has yin-yang, and earth also has yin-yang. Wood, fire, earth, metal, water, and fire are the yin-yang of earth, and growth, transformation, and storage. Thus, within yang there is yin, and within yin there is yang. Therefore, to understand the yin-yang of heaven and earth, one must respond to the qi of heaven, which moves without ceasing, hence it shifts to the right every five years; and respond to the qi of earth, which remains still and holds its position, hence it cycles every six years. (9). Movement and stillness summon each other, upper and lower realms face each other, yin and yang interweave, and thus change is born.
The Emperor asked: The cycles and periods of the upper and lower realms (10), are there numbers for them? Guiyuqu replied: Heaven takes six as its node, earth takes five as its rule. Those who cycle the qi of heaven, six periods make a preparation, those who end the period of earth, five years make a cycle. Monarch fire is for brightness, ministerial fire is for position (11). Five and six combine to make seven hundred and twenty qi, which is a period, thirty years in all, one thousand four hundred and forty qi, sixty years in all, and that is a cycle, deficiency and excess, all these are seen.The Emperor said: Your words, ending with the qi of heaven above and completing the period of earth below, can be said to be thorough. I wish to hear and store them, to govern the people above and govern myself below, to make the common people clear, to harmonize and be close above and below, to let virtue and grace flow down, to let descendants be without worry, to pass them on to later generations, without end, can I hear this? Guiyuqu replied: The mechanism of the ultimate numbers (12), pressing close and subtle (13), their coming can be seen, their going can be pursued, those who respect them prosper, those who neglect them perish, without the way and acting selfishly, one will surely suffer heaven's calamity, carefully follow the way of heaven, please speak the true essentials.
The Emperor said: Those who speak well of the beginning, must meet the end, those who speak well of the near, must know the far, thus the ultimate numbers reach the extreme and the way is not confused, this is called clarity, I wish for you to push and order them, to make them orderly, simple but not lacking, lasting but not ending, easy to use and hard to forget, to make them the guiding principles, the essentials of the ultimate numbers, I wish to hear them all. Guiyuqu replied: How clear is your question, how bright is the way, like the drum responding to the drumstick, the echo responding to the sound. I have heard, in the years of Jia and Ji, earth movement governs. In the years of Yi and Geng, metal movement governs. In the years of Bing and Xin, water movement governs. In the years of Ding and Ren, wood movement governs. In the years of Wu and Gui, fire movement governs.
The Emperor asked: How about their combination with the three yin and three yang? Guiyuqu replied:
