Another one is easy for you to ask me: what do the eight characters and five elements represent in the body and how do they circulate? This is a medical problem. On Yin and Yang in Huangdi Neijing Part V: Yin and Yang are the way of heaven and earth, the discipline of all things, the mother of change, the source of life and death, and the house of God. Treatment must be based on this. Therefore, the product of yang is the sky, and the product of yin is the ground. Yin is static and Yang is impetuous, Yang generates Yin, and Yang kills Yin and hides. Yang qi, yin forming. Extreme cold produces heat, and extreme heat produces cold. Cold is turbid, and heat is clear.
East wind, wind and wood, wood produces acid, acid produces liver, liver produces tendons, tendons produce heart, and liver governs eyes. There is mystery in heaven, humanity in man and humanity in earth. Metaplasia has five flavors, Taoism gives birth to wisdom, and metaphysics gives birth to gods. God is the wind of the sky, the wood of the earth, the muscle of the body, the dirty liver, the pale color, the horn of sound, the roar of sound, the grip of change, the eyes of ignorance, the sour taste and the anger of will. Anger hurts the liver, and sorrow is better than anger; Wind hurts the tendons, and dryness wins the wind; Sour hurts the tendons, and spicy tastes better than sour.
In the south, fire is hot, and fire produces bitterness, and bitterness produces heart, and heart produces blood, and blood produces spleen, and heart governs tongue. Hot weather, fire, pulse, heart, red color, vocal signs, laughter, anxiety, pain in the mouth, bitter taste, joy in the heart. Happiness is sad, fear is better than happiness; Heat hurts qi, cold beats heat; Bitter hurts the spirit, salty is better than bitter.
The middle part is wet, the wet part is soil, and the soil tastes sweet, which gives birth to spleen, spleen gives birth to meat, and meat gives birth to lung, and spleen governs the mouth. It is wet in the sky, dirty in the ground, meat in the body, dirty in the spleen, yellow in color, palace in sound, qu in sound, rushing to change, mouth in mouth, sweet in taste, thinking in the heart. Thinking hurts the spleen, and anger overcomes thinking; Wet meat, wind wins wet; Sweet hurts meat, sour is not as sweet as sweet.
West produces dryness, dryness produces gold, gold produces pungent, pungent produces lung, lung produces moss, and moss produces kidney, and lung governs nose. The sky is dry and the earth is golden, with fur on the body, lungs in the dirty, white in the color, business in the sound, crying in the sound, cough in the change, stuffy nose, pungent taste and worry in the heart. Sad for the lungs, joy wins sorrow; Heat hurts fur, and cold is better than heat; It hurts the fur, and bitterness is better than bitterness.
Cold in the north produces water, water is salty, kidneys are salty, kidneys have marrow, livers have marrow, and ears have kidneys. The cold of the sky, the water of the earth, the bones of the body, the dirty kidney, the black color, the feather of the sound, the groan of the sound, the chestnut of change, the ignorance of the ear, the salty taste and the fear of ambition. Afraid of hurting the kidney, think more afraid; Cold hurts blood, and dryness overcomes cold; Salty hurts blood, and sweet is better than salty.
Therefore: heaven and earth, everything is up and down; Yin and Yang, the blood of men and women; Left and right, the way of yin and yang is also; Fire and water are signs of yin and yang; Yin and yang, everything can only be. Therefore: yin contains something, and yang keeps it; Yang is outside, so is Yin.
Chapter 52 of Huangdi Neijing, written by Wei Qi, said: The five elements conform to the twelve meridians, with chest qi passing through, abdomen qi passing through, head qi passing through, and so on. As for how the eight characters and five elements circulate in the body, it belongs to the medical category, so I won't elaborate here.
