Each of us is a soul. We have been told that we "have" a soul, but that's not the same thing. To have a soul would indicate that we are primarily an ego or a personality that in some way "possesses" a soul. Our essence IS the soul and all aspects of ego and personality flow from that essence. At its core the soul is pure, but habits, tendencies, and imbalances often obscure some of that inner light. Our spiritual work is to correct whatever shortcomings may be preventing the light of our sould from shining through.
If we would return to God, and find ourselves in God, we must reverse Adam and Eve's journey, we must go back by the way they came. The path lies through the center of our own soul. Adam and Eve withdrew into themselves from God and then passed through themselves and went forth into creation. We must withdraw ourselves from exterior things, and pass through the center of our souls to find God. We must recover possession of our true selves by liberation from anxiety and fear and inordinate desire.
