Where does this sentence come from? "Zhuangzi", the original text is as follows:
My life is limited, but so is my knowledge. With the limit, there is no limit, and it is almost there; Knowing what you already know is almost enough. Good has no near name, and evil has no near punishment. The Governor thinks that classics can preserve our health, nurture our life, support our loved ones and last for several years.
Vernacular translation
Human life is limited, but knowledge is infinite. Pursuing infinite knowledge with limited life will inevitably lead to exhaustion, so it is really dangerous to continue pursuing knowledge! Do what the world calls good without coveting fame and fortune, and do what the world calls evil without facing the humiliation of punishment. Follow the righteousness of nature, as a constant method to conform to things, so as to protect themselves, preserve their nature, and let their parents have no worries and enjoy the rest of their lives.
Extended data:
Zhuangzi's Master of Health Preservation is an article about the way of health preservation. "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.
Zhuangzi advocated "knowledge/ignorance", that is, knowledge should be clearly distinguished instead of simply saying "the more the better" or "the less the better". By the way, the more you know, the better; By the way, the less you know, the better Therefore, seeking knowledge is not only a process of increasing knowledge, but also a process of identifying whether the acquired knowledge conforms to Tao and eliminating the knowledge that does not conform to Tao. The "Tao" here can be understood as truth.
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 health preservation between the lines, it actually reflects the author's philosophy and life purport.
