Worldly cleverness without faith and strength and trust is usually nothing but a delusion. It is the development of trust in the heart, the development of faith, that first gives a man a friendly attitude to himself; and he becomes his own friend by bringing his external being into harmony with his inner being. For it is when the inner being seeks one thing, and the external being does something else, that there is disharmony in the self. When the higher self desires to go one way, and the lower self another way, then there is disharmony, the result of which is like a volcanic eruption. The two parts of his own being which should unite together in love, clash together and the result is fire.
