Laozi said, Tao gives birth to one, which gives birth to two, two gives birth to three, and three gives rise to all things. This is a story about "immobility". Everyone was going up, and he was sinking. Sinking to the bottom of the well, sinking to a place where no one can see, I discovered that the Tao was not in the sky - it was at the lowest point, in a dry well, on the edge of the well where a black cat basked in the sun every day, and in the body of a man who everyone thought was useless. It's always been there, it was just too noisy to hear.
The world of immortality cultivation is moving from the Three to the Ten Thousand Things, striving to reach higher realms. He was alone, walking back by the dry well. Go back to the source. Go to that "nothing".
