"How does man, the victim of his desires and lower nature become man, the victor, triumph over the world, the flesh and the devil? It is brought about when the physical brain of the incarnated man becomes aware of the self, the soul, and this conscious awareness only becomes possible when the true self can "reflect itself in the mind-stuff.""
