Let nothing tempt you ever to compromise an ideal. Morality is not a question of convention. The Ten Commandments are engraved in human nature on tablets of light. The true reason why theft, violence, murder, and other crimes are wrong is that they hurt first of all the perpetrator himself, condemning him to ever-deeper dungeon levels in the rock fortress of his egoism. If you arm yourself, however, with truthfulness, honesty, and integrity, you will emerge someday into perfect soul-freedom.
