Mysticism may be considered as the essence of all knowledge. It may be likened to the perfume of a flower, for it has a fragrance of its own. We do not see the perfume, but we see the flower, and so we will not hear many words from the mystic to explain mysticism, but we can perceive that mysticism in his atmosphere. Mysticism may also be likened to honey. Honey is purifying and so is mysticism; it purifies man of his infirmities, and it is the sweetest of all the different aspects of knowledge that exist.
