This understanding of the part played by the Subjective Mind in controlling and affecting physical conditions and activities, together with its suggestible qualities and nature, gives us a key to the whole question of the "Why?" of Mental Healing. Suggestion is the connecting link between Mind and Body, and an understanding of its laws and principles enables one to see the moving cause of the strange phenomena of the Faith Cures, under whatever name they may pass, and under whatever guise they may present themselves. "Suggestion" is the explanation offered by the New Psychology for the almost miraculous phenomena which other schools seek to explain upon some hypothesis based either upon religious beliefs, or upon some metaphysical or philosophical doctrine. The New Psychology holds that it is not necessary to go outside of the realms of psychology and physiology in studying Mental Healing or Psycho-Therapy; and that the theories of the semi-religious and metaphysical cults are merely strange guises or masks which serve to conceal the real operative principle of cure. The following quotation from Dr. Schofield will serve to call the attention to the important part played by the Subconscious Mind in the physical activities, a fact which is not generally recognized: "It has often been a mystery how the body thrives so well with so little oversight or care on the part of its owner. No machine could be constructed, nor could any combination of solids or liquids in organic compounds, regulate, control, counteract, help, hinder or arrange for the continual succession of differing events, foods, surroundings and conditions which are constantly affecting the body. And yet, in the midst of this ever-changing and varying succession of influences, the body holds on its course of growth, health, nutrition and self-maintenance with the most marvelous constancy. We perceive, of course, clearly, that the best of qualities--regulation, control, etc., etc.--are all mental qualities, and at the same time we are equally clear that by no self-examination can we say we consciously exercise any of these mental powers over the organic processes of our bodies. One would think, then, that the conclusion is sufficiently simple and obvious--that they must be used unconsciously; in other words, it is, and can be nothing else than _unconscious mental powers_ that control, guide and govern the functions and organs of the body.
