Disease and health, like circumstances, are rooted in thought. Sickly thoughts will express themselves through a sickly body. Thoughts of fear have been known to kill a man as speedily as a bullet, and they are continually killing thousands of people just as surely, though less rapidly. The people who live in fear of disease are the people who get it. Anxiety quickly demoralizes the whole body and lays it open to the entrance of disease, while impure thoughts, even if not physically indulged, will sooner shatter the nervous system.
