The term "self" seems a suitable one for the unconscious substrate whose actual exponent in consciousness is the ego. The ego stands to the self as the moved to the mover, or as object to subject, because the determining factors that radiate outward from the self surround the ego on all sides and are therefore supraordinate to it. The self, like the unconscious, as an a priori existent out of which the ego evolves. It is, so to speak, an unconscious prefiguration of the ego. It is not I who create myself; rather, I happen to myself.
Carl JungThe unconscious is the only available source of religious experience. This in certainly not to say that what we call the unconscious is identical with God or is set up in his place. It is simply the medium from which religious experience seems to flow. As to what the further cause of such experience might be, the answer to this lies beyond the range of human knowledge.
Carl JungAnyone who wants to know the human psyche will learn next to nothing from experimental psychology. He would be better advised to abandon exact science, put away his scholar's gown, bid farewell to his study, and wander with human heart through the world.
