a false self and a real self

Commentary by Pir-o-Murshid Inayat Khan:

There is in man a false self and a real self. The real self contains the eternal; the false self contains the mortal. The real self has wisdom; the false self ignorance. The real self can rise to perfection; the false self ends in limitation. The real self has all good, the false self is productive of all evil. One can see both in oneself: God and the other one. By conquering the other one, one realizes God. This other power has been called Satan; but is it a power? In reality it is not. It is and it is not. It is a shadow. We see shadow and yet it is nothing. We should realize that this false self has no existence of its own. As soon as the soul has risen above the false self, it begins to realize its nobility.
