The fifth part "Huangdi Neijing" theory of Yin and Yang (4)

The sky is less than the northwest, so the northwest is cloudy, and people's right ear is not as bright as Zuo Ming; The land is not satisfied with the southeast, so the southeast is sunny, and people's left hand is not as strong as their right hand.

The emperor said: Why?

Qi Bo said: Yang is also in the east, and the essence of Yang is on the top, which makes the eyes and ears smart and the hands and feet inconvenient; In the west, Yin is also the essence of Yin, and the essence of Yin is consistent with the bottom, and the bottom is more than empty, so its eyes and ears are not bright, and its hands and feet are clumsy. So all people feel evil, the top is very right and the bottom is very left. This world can't be full of yin and yang, so evil lives in it.

Therefore, the sky is fine, the earth is tangible, the sky has eight disciplines and the earth has five miles, so it can be the mother of all things. It is the luck of heaven and earth, and the discipline of the gods, so you can grow and collect and start all over again. Only saints can support their heads with heaven, their feet with images, and their five internal organs with personnel. Natural qi can ventilate the lung, ground qi can ventilate the stomach, wind can ventilate the liver, Lei Tongxin, Gu Tongxin, Gu Tongxin, Spleen and Rain can ventilate the kidney. The six meridians are Sichuan, the stomach is the sea, and the nine orifices are the qi of water injection. Take heaven and earth as yin and yang, and the sweat of yang is named after the rain of heaven and earth; Yang Qi is named after the high winds of heaven and earth. Violent weather thunders and bad weather rises. Therefore, the rule of heaven without the principle of land is a disaster.
