If the ego is to perpetuate itself it must enter into all the mind's activities, not merely in the baser ones. This is exactly what does happen. The spiritual aspirations, the moral ideals, and even the mystical experiences are themselves inverted projections of the ego. Through them the "I" is able to expand itself into an "I" greater, grander, happier, and stronger than before. If they are not its own creations, providing shelter or disguise for it, then they are soon infiltrated and betrayed, undermined or permeated, until they feed and nourish the very self they were supposed to lead away from.
