Taxation of Mind and Body Tends to Prevent Impure Thoughts—The proportionate taxation of the powers of mind and body will prevent the tendency to impure thoughts and actions. Teachers should understand this. They should teach students that pure thoughts and actions are dependent on the way in which they conduct their studies. Conscientious actions are dependent on conscientious thinking. Exercise in agricultural pursuits and in the various branches of labor is a wonderful safeguard against undue brain taxation. No man, woman, or child who fails to use all the powers God has given him can retain his health. He cannot conscientiously keep the commandments of God. He cannot love God supremely and his neighbor as himself.— Letter 145, 1897 (1MCP 120.3) MC VC
