Constant self-effort can thin down the egoism but not eliminate it. That final act is impossible because the ego will not willingly slay itself. What self-effort does is to prepare the way for the further force which can slay it and thus makes the operation timely and its success possible. What it further does is to improve intelligence and intuition and to ameliorate the character, which also prepares the individual and attracts those forces. They are nothing else than the pardoning, healing, and, especially, the transforming powers of Grace.
