The mind is a storehouse, a storehouse of all the knowledge that one has accumulated by studies, by experiences, by impressions, through any of the five senses. In other words, every sound, even once heard, is registered there; every form that our eyes have seen, even a glimpse of it, is registered there. And when our heart is pure it projects the light of the soul just as the light is projected from a searchlight. And the most wonderful phenomenon is that the light is thrown by the power of will on that particular spot in the storehouse of the mind which we are wanting to find.
