The best way of cleansing the mind from all this is to be able to empty the mind of any thought, feeling or impression. To be pure means to be natural. The spirit in man in its natural condition is not a thought but mind, not love but heart. For as the thought is the outcome of mind so is love the outcome of the heart. To attain to the purity which is the seeking of the mystic one must be able to purify one's spirit from every thought and feeling, however deeply impressed or engraved in one's heart.
