Practice of Autosuggestion 
By the Method of Emile Coue

Autosuggestion is a type of therapy that calls on techniques such as hypnotism. Subjects use autosuggestion on themselves with the aim of curing bad habits, inculcating positive ones, boosting willpower, and even assuaging the symptoms of physical health problems. This practical treatise represents one of the first American publications to deal with the subject; it was produced in cooperation with Emile Coue, who pioneered the technique.
