Door of Tao

The passing geese leave their voices, the passing people leave their names, and the passing immortals leave their traces. The sound left in the wilderness has long since died out, the name left in history has turned into ashes, and the traces left in time and space have been erased. In the land of birth and death, the realm of reincarnation, the realm of truth and falsehood, I want to open the door to the Tao and see if there is a Tao outside the Tao.
