Paracelsus said that men who are devoid of the power of spiritual perception-what I call thought-are unable to recognize anything that cannot be seen externally. I come into this condition of awareness when I find myself. I am sure I have learned this much, not by intellect or scholarly attainment, but by pondering and, in pondering, discriminating. I discriminated, not between creeds or religions, but between true and false, important and unimportant, right and wrong, selflessness and selfishness.
