Again comes the question of the metaphysician or the philosopher when he reads all is God and God is all. He says, "If God is goodness, what then is the opposite of goodness? Is it outside God? If so, God is limited. Then something else exists as well as God. Are there two powers, rival powers? What is the power called evil?" It is true that God is all, but you would not call a man's shadow the man. What is evil then? It is only a shadow. What is illness? It is another illusion. In reality there is only life: real existence. Illness is lack of life; it is a shadow and an illusion.
