"God has managed, and perpetually manages, to insert into our nature a tendency toward health, and against the unnatural condition which we call disease. When our flesh receives a wound, a strange nursing and healing process is immediately commenced to repair the injury. So in all diseases, organic or functional, this mysterious healing power sets itself to work at once to triumph over the morbid condition.... Cannot this healing process be greatly accelerated by a voluntary and conscious action of the mind, assisted, if need be, by some other person? I unhesitatingly affirm, from experience and observation, that it can. By some volitional, mental effort and process of thought, this sanative colatus, or healing power which God has given to our physiological organism, may be greatly quickened and intensified in its action upon the body. Here is the secret philosophy of the cures effected by Jesus Christ.... There is a law of the action of mind on the body that is no more an impenetrable mystery than the law of gravitation. It can be understood and acted upon in the cure of disease as well as any other law of nature." If, then, it be possible through this process to change physical conditions in the body even after they have taken form and have become fixed, as we say, isn't it possible even more easily to determine the type of cell structure that is grown in the first place? The ablest minds in the world have thought and are thinking that if we could find a way of preventing the hardening of the cells of the system, producing in turn hardened arteries and what is meant by the general term "ossification," that the process of aging, growing old, could be greatly retarded, and that the condition of perpetual youth that we seem to catch glimpses of in rare individuals here and there could be made a more common occurrence than we find it today. The cause of ossification is partly mental, partly physical, and in connection with them both are hereditary influences and conditions that have to be taken into consideration. Shall we look for a moment to the first? The food that is taken into the system, or the available portions of the food, is the building material; but the mind is always the builder.
