Swami Vivekananda, Practical Vedanta

 “Thou art That". This is the essence of Vedanta; after all its ramifications and intellectual gymnastics, you know the human soul to be pure and omniscient, you see that such superstitions as birth and death would be entire nonsense when spoken of in connection with the soul. The soul was never born and will never die, and all these ideas that we are going to die and are afraid to die are mere superstitions. [...] The Vedanta teaches men to have faith in themselves first. As certain religions of the world say that a man who does not believe in a Personal God outside of himself is an atheist, so the Vedanta says, a man who does not believe in himself is an atheist.”
