“This Life Principle of the All is the Principle of Health in man, and becomes constructively active whenever man thinks in a certain way. Whoever, therefore, thinks in this Certain Way will surely have perfect health if his external functioning is in conformity with his thought. But the external functioning must conform to the thought; man cannot hope to be well by thinking health, if he eats, drinks, breathes, and sleeps like a sick man.
The universal Life Principle, then, is the Principle of Health in man.It is one with original substance. There is one Original Substance from which all things are made; this substance is alive, and its life is the Principle of Life of the universe. This Substance has created from itself all the forms of organic life by thinking them, or by thinking the motions and functions which produce them.
Original Substance thinks only health, because It knows all truth; there is no truth which is not known in the Formless, which is All, and in all. It not only knows all truth, but it has all power; its vital power is the source of all the energy there is. A conscious life which knows all truth and which has all power cannot go wrong or perform function imperfectly; knowing all, it knows, too much to go wrong, and so the Formless cannot be diseased or think disease.
Man is a form of this original substance, and has a separate consciousness of his own; but his consciousness is limited, and therefore imperfect. By reason of his limited knowledge man can and does think wrongly, and so he causes perverted and imperfect functioning in his own body. Man has not known too much to go wrong. The diseased or imperfect functioning may not instantly result from an imperfect thought, but it is bound to come if the thought becomes habitual. Any thought continuously held by man tends to the establishment of the corresponding condition in his body.
Also, man has failed to learn how to perform the voluntary functions of his life in a healthy way. He does not know when, what, and how to eat; he knows little about breathing, and less about sleep. He does all these things in a wrong way, and under wrong conditions; and this because he has neglected to follow the only sure guide to the knowledge of life. He has tried to live by logic rather than by instinct; he has made living a matter of art, and not of nature. And he has gone wrong.
His only remedy is to begin to go right; and this he can surely do. It is the work of this book to teach the whole truth, so that the man who reads it shall know too much to go wrong.”
