An avatar is an incarnation of God. The religious viewpoints on who or what an avatar is vary greatly. In Christianity, Jesus is an avatar. In Mexican Shamanism, the Psilocybin mushroom is an avatar. They refer to it as “teonanacatl” or literally, “The Flesh of God.” Buddhism does not admit the existence of a God and therefore does not admit the existence of an avatar either. They also strongly assert the lack of existence of a self. And to their credit, they back it up with a solid practice to supplement their theory.
The set of teachings that currently interest the author are those which assert that you are God.
