Starting from the origin theory, Buddhism reveals that man is empty, law is empty and everything is empty. But if everything is "empty", goals, ideals and conversions. In order to prevent this, Buddhism also proposed that there is an entity characterized by emptiness, which is independent and eternal, and it is "Nirvana _". Buddhism affirms the existence of nirvana. Is this contradictory to its world view that everything is empty? The answer is no, Buddhism says that "everything is empty", which is aimed at the "promising method" born of karma. Nirvana _ the world does not belong to the "inaction law" created by karma, but belongs to the "inaction law" created by non-karma, so it does not belong to the category of "emptiness". In this sense, "Nirvana _" is also translated as "lifeless", "inaction" and "immobile".
Legend has it that the phoenix is the messenger of human happiness. Every 500 years, it will bear all the unhappiness and hatred accumulated in the world, throw itself into flames, and exchange the end and beauty of life for peace and happiness in the world. It is also after the body has experienced great pain and tempering that they can be reborn with a better body. This story and its figurative meaning are called "Nirvana _" in Buddhist scriptures.
