The way a man thinks about things is determined by what he believes about them. His thoughts are determined by his faith, and the results depend upon his making a personal application of his faith. If a man has faith in the efficacy of a medicine, and is able to apply that faith to himself, that medicine will certainly cause him to be cured; but though his faith be great, he will not be cured unless he applies it to himself. Many sick people have faith for others but none for themselves. So, if he has faith in a system of diet, and can personally apply that faith, it will cure him; and if he has faith in prayers and affirmations and personally applies his faith, prayers and affirmations will cure him. Faith, personally applied, cures; and no matter how great the faith or how persistent the thought, it will not cure without personal application. The Science of Being Well, then, includes the two fields of thought and action. To be well it is not enough that man should merely think in a Certain Way; he must apply his thought to himself, and he must express and externalize it in his outward life by acting in the same way that he thinks.
Before man can think in the Certain Way which will cause his diseases to be healed, he must believe in certain truths which are here stated:--
All things are made from one Living Substance, which, in its original state, permeates, penetrates, and fills the interspaces of the universe. While all visible things are made from It, yet this Substance, in its first formless condition is in and through all the visible forms that It has made. Its life is in All, and its intelligence is in All.
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.
