The heavens have five elements of vitality, and all things are formed from this. The purity of wood produces benevolence, the purity of fire produces etiquette, the purity of gold produces justice, the purity of water produces wisdom, and the purity of earth produces honesty. When the five qi are pure, the virtues of the saints are possessed. The turbidity of wood gas produces weakness, and the turbidity of fire gas is cloudy
When it produces obscenity, the turbidity of gold gas produces tyranny, the turbidity of water vapor produces greed, and the turbidity of earthy gas produces stubbornness. If all five qi are cloudy, they become indecent people. The Central Plains produced many saints because the qi of neutralization blended with each other. Monsters are often produced in remote areas because of strange qi. If you uphold a certain yuan qi, you must have a certain form; If it has a certain form, it must have a certain property. Therefore, those who eat grain are smart and literate, those who eat grass are powerful and ignorant, those who eat mulberry leaves and become moths, those who eat meat are brave and strong, those who eat soil have no mind and do not rest, those who eat vitality are bright and live long, and those who do not eat do not die and become gods. Turtles and shrews have no males, and bees have no females; No males mate with other animals, and no females are born from other animals. Silkworm insects, which lay eggs first and then mate; Fragrant beasts, which have their own sexual organs. Parasitism is attached to tall trees, female lotus is in poria, trees grow in soil, duckweed is born in water, bird wings can fly in the air, beast feet can run, insects lurk in the soil to hibernate, fish hide in the abyss to live. From the heavens to the heavens, from the earth to the earth, from the seasons of the dependents of the things: it is dependent on their respective species. The thousand-year-old pheasant, entering the sea to become a mirage; A hundred years of finches, into the sea to become clams; A thousand-year-old turtle, able to talk to people; A thousand-year-old fox, capable of becoming a beauty; A thousand-year-old snake, the body is broken and can be picked up; A hundred-year-old rat can divine the auspiciousness: it is that the number of qi has been reached. At the time of the spring equinox, the eagle turns into a dove; At the autumn equinox, the dove turns into an eagle: it is the change of the season. So rotten grass becomes fireflies, decaying reeds become crickets, rice becomes black worms, and wheat becomes butterflies; Feathered wings are born, eyes grow, and there is a mind: this is a change from ignorance to perception. The crane becomes a roe deer, the snake becomes a turtle, and the cricket becomes a shrimp, without losing its flesh and blood, and the nature of the body changes. There are too many things like this to say. To act according to change is to conform to the laws of nature; If you violate its laws, you will become a demon. Therefore, the lower minister of the body is in the upper part, and the upper minister is in the lower part, which is the rebellion of the yuan qi; The birth of the beast, the birth of the beast, is the disorder of the yuan qi; The transformation of men into women, and the transformation of women into men, is the change of vitality. Lu Ren Niu fell ill and turned into a tiger after seven days, his body changed, and he grew tiger claws and tiger teeth. His brother opened the door and went in, where he was bitten to death by a tiger and eaten. When he was a man, he did not know that he was going to become a tiger; When he was a tiger, he didn't know that he had been a man. Therefore, during the reign of Emperor Taikang of the Jin Dynasty, Ruan Shiyu, a Chenliu man, was poisoned by cockroaches, could not bear the pain of poison, sniffed poisonous sores many times, and later found that there were two clams growing in the nose. During the Reign of Emperor Yuankang of the Jin Dynasty, the Liyang people ate the Taoist god turtle, and later had a fistula, the doctor used medicine to treat him, excreted a few liters of small turtles, one by one as big as a small copper coin, the head and feet are complete, the floating armor has patterns and horns, but the medicinal properties have died. Couples are not fertile vitality, the nose is not a place for pregnancy and conception, and the things that sacrifice to the gods are not something that ordinary people can eat. From this point of view, if the life and death of all things and their changes, if not magical speculation, even if they are deduced from itself, how can we know where they came from? However, the decaying grass becomes a firefly, due to the decay of the grass; The wheat turns into butterflies because the land is damp. Then there is a reason for the change of all things. The farmer stops the change of the wheat and uses ash to defuse it; The saint governs the change of all things and uses the "Taoism" to help it. Isn't that the case?
