"My life is limited, but I know it is infinite. It means that a person can see the margin of his life, but he can't see the object of cognition. Follow the invisible cognitive object with the life with visible margin, and the danger is approaching; Danger is approaching, but follow the cognitive object that can't see the margin. The danger has come.

From "Three Masters of Health Preservation in Zhuangzi", its original text is, "My life is limited, but my knowledge is also limited. With restrictions, there is no restriction, and it is almost there! It's almost enough for people who already know! Good has no near name, and evil has no near punishment. The Governor thinks that he can protect himself, support his relatives all his life, and work for many years. "

Thought:

This is an article about keeping in good health. "Health Master" is the key to health. Zhuangzi believes that the way to keep fit is to conform to nature, forget your feelings and not be trapped by foreign things.

The full text is divided into three parts. The first part is "You can spend all your years", which is the general outline of the whole article. It is pointed out that the most important thing for health preservation is to "know the classics from the edge", that is, to adhere to the virtual Tao in things and adapt to the changes and development of nature. The second part, How to Keep Healthy, compares people's health with the decomposition of cows' bodies by chefs, explaining that life and life should be "nature-oriented" and "sky-oriented", and only by taking virtual "space" for yourself can we be "comfortable", thus avoiding the entanglement of right and wrong and contradictions. The rest is the third part, which further explains the attitude of "obeying fate, conforming to nature and being safe and smooth".

The center of Zhuangzi's thought is, on the one hand, helpless freedom, and on the other hand, opposing letting nature take its course. Although this article talks about keeping in good health between the lines, it actually reflects the author's philosophy and life purport.
