WHAT man is, and what man does, determines in what conditions, circumstances and environments he shall be placed. And since man can change both himself and his actions, he can determine what his fate is to be.
To change himself, man must change his thought, because man is as he thinks; and to change his actions, he must change the purpose of his life, because every action is consciously or unconsciously inspired by the purpose held in view.
To change his thought, man must be able to determine what impressions are to form in his mind, because every thought is created in the likeness of a mental impression.
To choose his own mental impressions, man must learn to govern the objective senses, and must acquire the art of original thought.
