The body must be kept in a healthy condition in order that the soul may be in health. The condition of the body affects the condition of the soul. He who would have physical and spiritual strength must educate his appetite in right lines. He must be careful not to burden the soul by overtaxing his physical or spiritual powers. Faithful adherence to right principles in eating, drinking, and dressing is a duty that God has laid upon human beings. (TDG 185.5) MC VC
