The Mind Cure by Christian Larson 

IT IS a well-known fact that a considerable majority of the people in this country are addicted more or less to nervousness in one or more of its many forms; and as nervousness is the direct cause of all mental ills, and the indirect cause of a great many physical ills, organic as well as functional, there are few things that would be more important than that of finding a method through which health for the nerves could be secured. How to cure this malady has long been a problem. Medicine as a rule avails but little, and the various forms of other therapeutic systems reach but a limited number. It is therefore that the discovery of a remedy that could reach all cases, or nearly all cases, would easily be considered one of the most remarkable discoveries of the age.
