On the contrary, repetition is the movement of Tao, and weakness is the function of Tao. Everything in the world is born in the tangible, and the tangible is born in the intangible. The most important feature of Tao is the reversion and regression of all things. Everything is from scratch, and finally from scratch. It really means that everything in the world is born out of nothing and out of nothing. How to make everything return to the Tao, using the weakening method. For example, people are in a state of nothingness before birth, they are there after birth, and they return to nothingness after death! The process of human growth is the process from growth to death, from initial growth to strength, and finally weakened by Tao, which leads to nothing! At the same time, this process has been accompanied, never give up! This kind of thought is similar to Buddhism's "breaking the void" and the original "truth of law" thought.
