“The true teacher defends his pupils against his own personal influence.”
LXXX. TEACHER
Orphic Sayings
Context: The true teacher defends his pupils against his own personal influence. He inspires self-trust. He guides their eyes from himself to the spirit that quickens him. He will have no disciples. A noble artist, he has visions of excellence and revelations of beauty, which he has neither impersonated in character, nor embodied in words. His life and teachings are but studies for yet nobler ideals.

Original quote:
For my friend said that he opened his intellect as the sun opens the fans of a palm tree, opening for opening's sake, opening infinitely for ever. But I said that I opened my intellect as I opened my mouth, in order to shut it again on something solid. I was doing it at the moment. And as I truly pointed out, it would look uncommonly silly if I went on opening my mouth infinitely, for ever and ever.
