**Rest.** Just as necessary as is food or exercise, is the change called rest. If the same muscles be exercised continuously they will surely tire and good work can, then, no longer be done with them. Regular rest should be given the body. Frequently, a change from one kind of work to another is a sufficient rest; but in many cases, cessation from effort is necessary to recuperate man's strength, properly. The natural law requiring regular sleep should be obeyed, though none should sleep too long. One day out of seven, the Sabbath, should be devoted, particularly, to matters concerning God and the spiritual life, which too often are submerged during the other days, in the material affairs of life. An occasional fasting is very desirable, since, for a few hours, it gives some organs of the body a complete rest. At present, the Church practice is to fast twenty-four consecutive hours once each month. The food thus saved, in conformity with the fundamental spirit of brotherhood, is distributed among those who have need of it, by ward officers specially appointed for that purpose. **Stimulants.** In normal health, food, exercise, rest, love of God and fellowman and daily work, furnish a natural and sufficient stimulation for all the duties of life. In fact, none other should be allowed, if the best physical health is to be retained. Therefore, alcohol in all its forms, tobacco, tea, coffee and the variety of drugs should not be used. There is double danger in the use of stimulants: first, they tend to undermine the strength of the man, and, second, they take away from man his mastery of himself. Under the influence of a drug, man is urged on by the drug itself, and not by his own strength of will. This is most dangerous. A man who loses control of himself, never knows just what he may do. **Moral Purity.** The body is much concerned in the moral purity of the man. Men and women must keep themselves pure or there will be a loss of life and procreative power. Moreover, men must keep themselves as pure as do women. No reasoning, based on natural law, justifies two standards of morality, one for the man and the other for the woman. **The Gospel and the Sound Body.** The sound body is a Gospel requirement, for only with a sound body can man work out his mission and have full joy. Working effectively and to make others happy, can be done only in a healthy body. Every effort should be made to keep our bodies as sound as possible. It is a part of a rational theology. CHAPTER 33. EDUCATION FOR THE INNER LIFE. After all, the body is only the tabernacle of the spirit. The spirit within, the essential part of man, must be developed as much as possible during the earth career.
