The way of keeping in good health advocated by Laozi is "let nature take its course, be indifferent without desire, be calm and peaceful". In fact, Lao Tzu is asking us to be less selfish, less greedy and less satisfied. This has also become the guiding ideology of Taoist health preservation for more than two thousand years.
In the Laozi cultural wall of Pingyang Square in Laojun Mountain, this mystery was revealed to us. This page shows Laozi's health pills. The content is: Jade furnace is used to burn medicine to prolong life, and the real way is to repair Yishou Dan. Inhale and exhale, I am the one who can't see the emptiness of sex. Silent photos can forget me, in order to see the nature before death. Lead and mercury are handed over to the gods, and Gan Kunming is a group of immortals.
The characters in Laozi's secret of alchemy are different from ordinary Chinese characters, and his structure is composed of more than two Chinese characters. This special method of word-making embodies the understanding of Dan Dao by Taoist Dante. At the same time, it also shows us the secret of Taoist health preservation: the word "medicine" in the first sentence "burning medicine in jade furnace to prolong life" is composed of "self, home and water", and the body fluid produced by human body, that is, "home water", is used as raw material to burn medicine to prolong life. There is a saying of swallowing body fluid in Taoist fitness theory. They think that the body fluids in their bodies are medicines, which should not be discarded casually, but should be swallowed all the time. The main component of saliva is amylase, which plays a very important role in the whole digestive tract. Therefore, the understanding of Taoism is not unreasonable. It should be said that it is basically scientific to understand medicine as domestic water, so the three-character combination of domestic water has become the word medicine.
The word "behavior" in the second sentence consists of "people, law and mind". The human heart is quiet, but those who can't keep it will become lost because of selfish desires. Chapter 19 of Tao Te Ching talks about "simplicity, selfishness and no desire". The way of keeping in good health advocated by Laozi is "let nature take its course, be indifferent without desire, be calm and peaceful". In fact, Lao Tzu is asking us to be less selfish, less greedy and less satisfied. This has also become the guiding ideology of Taoist health preservation for more than two thousand years.
