He who enters upon this renovating regime should first equip himself with enough knowledge about it, for he is likely to run into difficulties and complications, become disheartened, and even abandon it. He ought to know what course it usually takes and what he may expect. He should particularly learn about the alternations of feeling, the rise and fall of vitality, the appearance of different symptoms, and the correct ways in which to meet them. At certain times, healing crises will manifest themselves and these will constitute his hardest problem. The process of dissolving and eliminating the fermenting and decaying materials from the cellular tissues will become very potent at such times, and its outer indications may well frighten him into belief that the whole system is wrong, that he ought never to have tried to follow it. It is then that he will need the hand of reassurance from those who have travelled the whole course and have realized with joy the incredible benefits that wait at its end--the cure of their ailments and the rejuvenation of their organs. Therefore it is better that before he begins such a radical changeover from conventional regimes, and especially before a fast, he ought to learn more about the experiences of others who have followed this new course. This he can do by reading the literature on the subject. He will not be groping in the dark but will know where he is going and what he is doing.
