The frequent employment of one's will power masters all organs of movement and trains them to perform feats which otherwise would have been difficult,painful and even impossible. The man becomes independent and self-reliant; he will never be a coward,and, when real danger threatens,he is the one who is looked up to by others. The knowledge of one's strength entails a real mastery over oneself; it breeds energy and courage,helps one over the most difficult tasks of life, and procures contentment and true enjoyment of living.
