The living are yang and the dead are yin. As the inspector of the underworld, Hua Yunfan protects the people and the heaven and earth, thereby creating the underworld and establishing the underworld.
Buddha said: Looking back five hundred times in the past life is only one passing by in this life. We passed each other five hundred times in the previous life, in exchange for one encounter in this life. Five hundred encounters in the past life are exchanged for one acquaintance in this life. Five hundred acquaintances in the past life are exchanged for one acquaintance in this life. We knew each other five hundred times in the previous life, in exchange for one love in this life.
This is called reincarnation.
