But where, it will naturally be asked, is this wonderful, mystic Power to be contacted? Where may we find it? And how is it brought into action? The answer is perfectly simple — This Power is to be found within your own consciousness, the last place that most people would look for it. Right within your own mentality there lies a source of energy stronger than electricity, more potent than high explosive; unlimited and inexhaustible. You only need to make conscious contact with this Power to set it working in your affairs; and all the marvelous results enumerated can be yours. This is the real meaning of such sayings in the Bible as "The Kingdom of God is within you" and "Seek ye first the Kingdom of God, and all the rest shall be added."
