_The Original Intelligent Substance is in man, moving toward health; and it is pressing upon him from every side. Man lives, moves, and has his being in a limitless ocean of health-power; and he uses this power according to his faith. If he appropriates it and applies it to himself it is all his; and if he unifies himself with it by unquestioning faith, he cannot fail to attain health, for the power of this Substance is all the power there is._ A belief in the above statements is a foundation for faith in health. If you believe them, you believe that health is the natural state of man, and that man lives in the midst of Universal Health; that all the power of nature makes for health, and that health is possible to all, and can surely be attained by all. You will believe that the power of health in the universe is ten thousand times greater than that of disease; in fact, that disease has no power whatever, being only the result of perverted thought and faith. And if you believe that health is possible to you, and that it may surely be attained by you, and that you know exactly what to do in order to attain it, you will have faith in health. You will have this faith and knowledge if you read this book through with care and determine to believe in and practice its teachings. It is not merely the possession of faith, but the personal application of faith which works healing. You must claim health in the beginning, and form a conception of health, and, as far as may be, of yourself as a perfectly healthy person; and then, by faith, you must claim that you ARE REALIZING this conception. Do not assert with faith that you are going to get well; assert with faith that you ARE well. Having faith in health, and applying it to yourself, means having faith that you are healthy; _and the first step in this is to claim that it is the truth_. Mentally take the attitude of being well, and do not say anything or do anything which contradicts this attitude. Never speak a word or assume a physical attitude which does not harmonize with the claim: "I am perfectly well." When you walk, go with a brisk step, and with your chest thrown out and your head held up; watch that at all times your physical actions and attitudes are those of a healthy person. When you find that you have relapsed into the attitude of weakness or disease, change instantly; straighten up; think of health and power. Refuse to consider yourself as other than a perfectly healthy person. One great aid--perhaps the greatest aid--in applying your faith you will find in the exercise of gratitude. Whenever you think of yourself, or of your advancing condition, give thanks to the Great Intelligent Substance for the perfect health you are enjoying.
