The greatest lesson of mysticism is to know all, gain all, attain all things and be silent. The more the disciple gains, the more humble he becomes, and when any person makes this gain a means of proving himself in any way superior to others, it is a proof that he does not really possess it. He may have a spark within himself, but the torch is not yet lighted. There is a saying among the Hindus that the tree that bears much fruit bows low.
