Welcome guests during the day and ghosts at night. Don't ask about people or ghosts. The door of life is closed, the door of death is open, there is nothing left to do about life and death. The ghost of impermanence, the one who attracts souls, is by the bridge of Naihe. Whether in life or in death, the mortal world is just a dream. There are eight kinds of suffering in the world, and all kinds of suffering are involved. The pain of the five yins is black mulberry and hibiscus. Matters of life and death are endless. There is no such thing as a sad person in this world.
