So the language of ideas cannot be heard by the ears alone, the hearing of the heart must be open for it. The seer must understand from a word spoken to him what even the one who speaks does not know, for every human being thinks, speaks, and acts mechanically, subject to the condition of his body, mind, and situation in life. Therefore as a physician finds out more about a complaint than the patient himself, so the mystic must comprehend the idea behind every word that is spoken to him. One might think with the continual growth of such perception the life of a Sufi must become very much troubled, for when the average person would be seeing a yard's distance a Sufi may be seeing the distance of a mile. Yet, there is no doubt it could be troublesome if the mystic did not develop all around. The elephant's strength is required to carry the load of an elephant. It is not enough to become a seer alone, but what is needed is to develop that strength which takes all things easily, the power that endures all things, and the might which enables one to surmount all difficulties in life.
