The meaning of this sentence is: If people can follow the nature of nature and grasp the "six qi", that is, the laws and changes of all things in the universe such as yin, yang, wind, rain, darkness, and brightness, they can travel in the endless world. In this realm, what else can he rely on?

Source: Zhuangzi's "Xiaoyaoyou"

Excerpt:

There are countless people who have brought happiness. Although this is unnecessary, there is still something to be expected. If you take advantage of the righteousness of heaven and earth and guard against the debate of the six qi, and you want to swim infinitely, how can you treat him badly? Therefore, it is said: A perfect person has no self, a god has no merit, and a saint has no name.

Translation:

He did not desperately pursue the matter of attracting good fortune. But although he is freed from the labor of walking, he still has to rely on something. If a person can follow the nature of nature, grasp the laws and changes of all things in the universe such as yin, yang, wind, rain, darkness, and brightness, and travel through endless realms, what else will he rely on? Therefore, it is said that people with the highest moral cultivation can adapt to the objective and forget themselves; those who have reached the unpredictable state of deification have no intention of seeking merit; and saints with moral knowledge have no intention of seeking fame.

Text Appreciation

Zhuangzi proposed the opposite concepts of "waiting" and "no waiting". "Waiting" means the necessary conditions. For example, Liezi walks on the wind, and his freedom is waiting. As for the wind, it is restricted by the wind it is waiting for and cannot be absolutely free. Only by "no waiting" and getting rid of the restrictions of conditions can you be absolutely free. The state of "no waiting" pursued by Zhuangzi does not exist in the real world, but is an absolute spiritual world.

Zhuangzi also proposed that the function of things is always related to certain conditions. Things that are useful under one condition will become useless under another condition. For example, people from the Song Dynasty to Yue The country sells hats, and the Yue people cut off their hair and get tattoos on their bodies. If they don't use them, the hats become useless. Zhuangzi emphasized the relationship between external conditions and human behavior, reflecting the profoundness of his understanding. But his pursuit of a state of absolute freedom without any restrictions is an unrealistic fantasy.
