Shi Ming said: "Being old and not dying is immortal."
This concept is not respected in Buddhism, so, although there are different opinions about the legend of immortals, it is only the talk of people under the door.
Speaking of immortals who can keep in good health, there is such a record in Bao Puzi:
Or someone asks, "Peng Zu 800 yuan, the safety period is 3,000 yuan, so he lives a long life. If there is a way to live forever, why not become an immortal? If you don't have to suffer indignities, you must mend it. Occasionally, you can't delay it. There is no way. "
Bao Puzi said, "Peng Zu scripture says that he is assisting Yao and practicing medicine in Yin in summer. Yin Wang sent a colorful girl from the government to master the skills, and the effect was good. He tried his best to kill Peng Zu. Peng Zu felt helpless and ran away. He was over 700 years old when he died, not for death.
An Qisheng, on the other hand, sells medicines by the sea, which has been passed down from generation to generation for thousands of years.
The foundation of Taoist health care thought still comes from "Taoism is natural" of Laozi and Zhuangzi, which is the core of Taoist health care, and the key of An Qisheng's so-called "three thousand not old" health care is also rooted in this.
Whether it is taking the bait, guiding, miscarriage, inner Dan, outer Dan, room, valley, etc. All kinds of body-keeping exercises are born from this.
Taoist theorists believe that man and heaven and earth are integrated: heaven and earth are a big universe, man is a small universe, and the big universe and the small universe are closely related.
Therefore, the most fundamental principle of health care practice is to learn from heaven and earth and conform to nature.
Zhuangzi also has "an emu's nest, a deep tree, but only one" in "Happy Travel"; The advice of "swallow a mouse and drink a river, but you are full" is the so-called contentment, and contentment prolongs life.
Because contentment is indisputable, it naturally avoids external interference, and achieves "keeping the spirit and simplicity", and then "having both form and spirit", returning to the pure child shape that Laozi admired and enjoying life.
This is also the reason why An Xian, a Taoist immortal admired by the world, can devote himself to it.
