During this development the disciple encounters harmony, pure knowledge, pure truth, in different degrees, and, as he enters these degrees, he finds himself becoming part of what might be roughly described as a layer of human consciousness. He encounters his equals, men of his own self-less character, and with them his association becomes permanent and indissoluble, because founded on a vital likeness of nature. To them he becomes pledged by such vows as need no utterance or framework in ordinary words. This is one aspect of what I mean by a Brotherhood.
