[I]t is easy to regard the mind and the body as two slaves trained to obey the imperial soul.... [I]n this trinity of soul, mind, and body, it is sometimes hard to tell which of the three is at work; and the personality of each of the three parties interferes a good deal with that of each of the others. But if you who read will remember that you are an infinite child of God, and can partake of his nature, and that you have given to you the management and direction of your mind and your body, you will be saved many failures.
