If the fast is to be of permanent benefit it is necessary to learn how to eat properly afterwards, and to put this knowledge into practice. This is the most important part to emphasize, yet all the books I have read on the subject have failed to pay any attention to it. In nearly every case the fast is necessary because of repeated mistakes in eating and drinking. Those mistakes built bodily ills in the first place and if the faster goes back to them they will do it again. The disease does not always take on the same type as it did in the first place, but it is the same old disease. During a fast there is recuperation because the body has a chance to become clean, and a clean body can not long remain unbalanced, provided there are no organic faults. By making mistakes in eating after the fast is over, the body again becomes foul and full of debris and that means more disease. Perhaps it may not require more than one-third as much abuse to cause a second break-down as it did to bring about the first one. Some people fast repeatedly, and are somewhat proud of it. They should be ashamed of the fact that they must fast time after time, for it shows either ignorance or a weak, undeveloped will power. The fast should teach every intelligent being that it is an emergency measure, and emergencies are but seldom encountered in a well regulated life. Food debauches following fasts should be avoided. A little will power properly applied will prevent them. Gross eating may compel another fast. We must eat and it is better to eat so that we can take sustenance regularly than to be compelled to go without food at various intervals. He who is moderate in his eating, uses a fair degree of intelligence in the selection of his food, is temperate in other ways and considerate and kind in his dealings with others will not be ill. A fast is efficacious in clearing up a brain that is unable to work well because it is bathed in unclean blood. It is remarkable how well the brain works when the stomach is not overworked. Overfeeding the body causes underfeeding of the brain. On a correct diet the brain is efficient and clear and able to bear sustained burdens. There is no question but that a fast, followed by a light diet, containing less of the heavily starchy and proteid foods and more of the succulent vegetables and fresh fruits, with their cleansing juices and health-imparting salts, would result in the recovery of over one-half of the insane. Most of them are suffering functionally and here the outlook is very hopeful. Christ cured a lunatic "by prayer and fasting." Proper feeding would work wonders in prisons. It would also be very beneficial for wayward girls and young men who are passion's slaves. St. Peter recommended fasting as an aid to morality, which is another evidence of the profundity of his wisdom.
