" Repetition of affirmation of orders to your subconscious mind is the only known method of voluntary development of the emotion of faith. Perhaps the meaning may be made clearer through the following explanation as to the way men sometimes become criminals. Stated in the words of a famous criminologist, "When men first come into contact with crime, they abhor it. If they remain in contact with crime for a time, they become accustomed to it, and endure it. If they remain in contact with it long enough, they finally embrace it, and become influenced by it. "
