“If you entertain healthy thoughts, you can keep good health. If you hold on to sickly thoughts in the mind, thoughts of diseased tissues, thoughts of weak-nerves, thoughts of improper functioning of organs or viscera, you can never expect good health, beauty and harmony. The body is the product of the mind. If you hold on vigorous thoughts in the mind, then the physical body also will be vigorous.
Evil thoughts of all kinds befoul and infure the mind and, if persisted in, will become veritable diseases and maimings of the mind, incurable during the period of life.”
