" Faith, belief, positive thinking, faith in God, faith in other people, faith in yourself, faith in life. This is the essence of the technique that teaches. “If thou canst believe,” it says, “all things are possible to him that believeth” (Mark 9:23). “If ye have faith … nothing shall be impossible unto you” (Matthew 17:20). “According to your faith be it unto you” (Matthew 9:29). Believe—believe—so it drives home the truth that faith moves mountains. "
