“The Intelligent Substance, from which all things are made, permeates and penetrates all things; and so it is in and through your body. It moves according to its thoughts; and so if you hold only the thoughts of perfectly healthy function, it will cause the movements of perfectly healthy function within you.
Hold with persistence to the thought of perfect health in relation to yourself; do not permit yourself to think in any other way. Hold this thought with perfect faith that it is the fact, the truth. It is the truth so far as your mental body is concerned. You have a mind-body and a physical body; the mind-body takes form just as you think of yourself, and any thought which you hold continuously is made by the transformation of the physical body into its image. Implanting the thought of perfect functioning in the mind-body will, in due time, cause perfect functioning in the physical body.”
