In the chapter on Abstinence it is suggested that one of the best things that men and particularly women could practice to advantage from the standpoint of religious abstinence would be abstinence from excessive rest. Rest is one of the most dangerous remedies that we have, nearly as dangerous as opium and with a definite tendency for a habit to be acquired by the system for it whenever it is indulged in to excess, exactly as is true of the opiates. If mortification of the spirit were to be practiced by abstinence from overrest and by a definite amount of exercise every day it would be an excellent thing for the religious as well as the physical life. This is one of the most frequent advices of those interested in the spiritual life as well as the bodily health for many generations. What people need is to keep busy. This is good for both their minds and their bodies. It requires a great deal of mortification of the inclinations to keep at work and above all to take exercise voluntarily when one might sit around and enjoy the delightfully lazy feeling of doing nothing, but that way lies serious disturbance of health. The men who have been very hard workers, especially from a sense of duty and not for mere selfish reasons, taking a great deal of exercise and going to bed so thoroughly tired every night that they went to sleep as soon as their head touched the pillow, have been long-lived as a rule, unless they met with some accident or infection. {324} Above all, it is important for any one who wishes to retain his self-respect and keep from that sluggishness which is so fatal to the power to pray and to meditate not to permit his abdominal and flank muscles to become overstretched and to allow fat to accumulate within the abdomen until it is actually a burden. There is almost no excuse for any one permitting his waist line to become larger in girth than his chest, unless of course he happens to have some deformity that makes exercise very difficult or practically impossible. To keep these muscles in good condition prevents slouchiness and makes the individual ever so much more ready for activity of any kind. The only way that these muscles can be kept in tone to hold in the abdomen properly and keep the circulation within it in such vigor as will support the digestive tract so as to permit and encourage its proper activities is by exercising them. This requires the performance of certain exercises every day. Stooping, bending, stretching, all these must be practiced if the muscles are not to be allowed to degenerate. There is no harder task than to keep up the custom of performing these exercises regularly a couple of times a day, for though only from five to ten minutes is needed night and morning to maintain the muscles in condition or even to restore them when they have once begun to sag, all sorts of excuses come in to prevent the regular practice of the exercises, and it is the regularity above all that counts.
