Nobody who thoroughly understands fasting, harbors any doubts about its possibilities and limitations. Most people who have voluntarily resorted to fasting for recovery from chronic illness, have done so as a last resort. They are usually in a very bad condition before they consent to fast. That the results have been so great, when we consider the type of patients that fast, is remarkable. That there are those who fast with only meager results must be expected, from the fact that so many of those who consent to fast are nearing death at the time. Fasting does not enable the body to accomplish miracles. But ninety-five per cent of chronic sufferers may undergo a properly supervised fast with every hope of good results.
