How did Sufis help their pupils, their mureeds, to develop their personality? Was it by telling them that this is right and that is wrong; or this is good and that is bad; or you must do this or you must do that? No, it was by establishing that current of sympathy through which the spirit of the teacher is reflected in the pupil, and the mureed begins to show forth his teacher in his thought, in his speech, and in his action. This training was considered most valuable among the Sufis of all ages, a training which is not given in words. For if a teacher has to correct his pupil in words it is perhaps only a scratch on the pupil, but on his own spirit it is a cut.
