[T]he teacher always corresponds to the level of the pupil. The higher the pupil, the higher can be the teacher. But a pupil of a level which is not particularly high cannot count on a teacher of a very high level. Actually a pupil can never see the level of the teacher. This is a law. No one can see higher than his own level. But usually people not only do not know this, but, on the contrary, the lower they are themselves, the higher the teacher they demand. The right understanding of this point is already a very considerable understanding. But it occurs very seldom. Usually the man himself is not worth a brass farthing but he must have as teacher no other than Jesus Christ. To less he will not agree. And it never enters his head that even if he were to meet such a teacher as Jesus Christ, taking him as he is described in the Gospels, he would never be able to follow him because it would be necessary to be on the level of an apostle in order to be a pupil of Jesus Christ. Here is a definite law. The higher the teacher, the more difficult for the pupil. And if the difference in the levels of the teacher and pupil go beyond a certain limit, then the difficulties in the path of the pupil become insuperable.
It is exactly in connection with this law that there occurs one of the fundamental rules of the fourth way. On the fourth way there is not one teacher. Whoever is the elder, he is the teacher. And as the teacher is indispensable to the pupil, so also is the pupil indispensable to the teacher. The pupil cannot go on without the teacher, and the teacher cannot go on without the pupil or pupils. And this is not a general consideration but an indispensable and quite concrete rule on which is based the law of a man's ascending. As has been said before, no one can ascend onto a higher step until he places another man in his own place. What a man has received he must immediately give back; only then can he receive more. Otherwise from him will be taken even what he has already been given."
