Besides, the Sufi Order is a mystical order, and there are certain thoughts and considerations which should be observed. First, when once a certain secret is entrusted, it must be kept as one's most secret and sacred trust. Second, take all the teachings that will be given, whether a bitter medicine or a sweet medicine, to the patient. Everything including illumination has a time; real progress depends upon the patience of the pupil, together with his eagerness to go forward.
