Much that was called religion has carried an unconscious attitude of hostility toward life. True religion must teach that life is filled with joys pleasing to the eye of God, that knowledge without action is empty. All men must see that the teaching of religion by rules and rote is largely a hoax. The proper teaching is recognized with ease. You can know it without fail because it awakens within you that sensations which tells you this is something you've always known.
