"From the mind of each of us there stretches an invisible thread. This links us with the inner Heavens, the place of all knowledge, and inspiration. Like a telephone wire, this thread is useless unless there is a receiving instrument at one end, and a person trying to establish a contact. We may spend our whole lives without ever properly using our invisible thread, or knowing that it is there. This is tragic, because there is no limit to what we can achieve by means of this magic link. The thread has been known and used by all the sages in history, and has been given many names."
