I agree. I have Manly P Hall's book The Secret Teachings if All Ages, and I used to listen to his lectures online...I learned a lot, and he shared it openly.

This caught my eye given Q: "Socrates did not force his opinions on others, but through the medium of questionings caused each man to give expression to his own philosophy. According to Plutarch, Socrates conceived every place as appropriate for teaching in that the whole world was a school of virtue. He held that the soul existed before the body and, prior to immersion therein, was endowed with all knowledge; that when the soul entered into the material form it became stupefied, but that by discourses upon sensible objects it was caused to reawaken and to recover its original knowledge."
