The self as the essence of individuality is unitemporal and unique; as an archetypal symbol it is a God-image and therefore universal and eternal.
Carl JungNot only does the psyche exist, but it is existence itself. It is an almost absurd prejudice to suppose that existence can only be physical...We might well say, on the contrary, that physical existence is a mere inference, since we know of matter only in so far as we perceive psychic images mediated by the senses.
Carl Jung
