Original: Eternal. The reason why heaven and earth can be long and long is that they are not born by themselves, so they can live forever. It is based on the sage's body and the body first, and the body exists outside. Not because of its selfless evil? Therefore, it can be private.

Vernacular translation: Heaven and earth exist for a long time. Heaven and earth can exist for a long time because they don't run and exist for themselves, so they can last for a long time. Therefore, saints put themselves behind, and as a result, they will take the lead; If you put yourself out of danger, you can save yourself. Isn't it because he is not selfish? So he achieved his own purpose. Expand the material

Taoist thought in The Tao Te Ching Eternal:

The most fundamental reason why heaven and earth can live forever is that they have no consciousness, no thoughts, and don't know that they are alive. Without the concept of life, there is no death. It is precisely because heaven and earth are unconscious that they don't know that they are in a state of survival, and of course there will be no death, so it is reasonable to live forever. Heaven and earth run according to the law of the avenue, and everything about them naturally exists.

Lao Tzu believes that we should follow the development law of the avenue, regard the development and change of everything in the universe as natural, and do not impose our own will on everything, so we can live and live with the avenue.
