This Substance creates by thought, and its method is by taking the form of that which it thinks about. The thought of a form held by this substance causes it to assume that form; the thought of a motion causes it to institute that motion. Forms are created by this substance in moving itself into certain attitudes or positions. When Original Substance wishes to create a given form, it thinks of the motions which will produce that form. When it wishes to create a world, it thinks of the motions, perhaps extending through ages, which will result in its coming into the attitude and form of the world; and these motions are made. When it wishes to create an oak tree, it thinks of the sequences of movement, perhaps extending through ages, which will result in the form of an oak tree; and these motions are made. The particular sequences of motion by which differing forms should be produced were established in the beginning; they are changeless. Certain motions instituted in the Formless Substance will forever produce certain forms. Man's body is formed from the Original Substance, and is the result of certain motions, which first existed as thoughts of Original Substance. The motions which produce, renew, and repair the body of man are called functions, and these functions are of two classes: voluntary and involuntary. The involuntary functions are under the control of the Principle of Health in man, and are performed in a perfectly healthy manner so long as man thinks in a certain way. The voluntary functions of life are eating, drinking, breathing, and sleeping. These, entirely or in part, are under the direction of man's conscious mind; and he can perform them in a perfectly healthy way if he will. If he does not perform them in a healthy way, he cannot long be well. So we see that if man thinks in a certain way, and eats, drinks, breathes, and sleeps in a corresponding way, he will be well. The involuntary functions of man's life are under the direct control of the Principle of Health, and so long as man thinks in a perfectly healthy way, these functions are perfectly performed; for the action of the Principle of Health is largely directed by man's conscious thought, affecting his sub-conscious mind.
