It is not only the faith and devotion one has for one's teacher which counts, but also the effacing of one's self, because the teacher's work is like that of a goldsmith who melts the gold and then makes an ornament out of it. Therefore the teacher has to test and to try, to mold and to melt before he can use the pupil for a better purpose. If a pupil cannot give himself to that molding, then he will have a difficult time.
