the self is a more comprehensive thing which includes the experience of the ego and therefore transcends it. Just as the ego is a certain experience I have of myself, so is the self an experience of my ego. It is, however, no longer experienced in the form of a broader or higher ego, but in the form of a non-ego.
Jung defines the Transcendent Self as the psychic totality that encompasses and supersedes the ego, experienced not as an enlarged ego but as an essentially non-ego mode of being.
