Two Classics in One: Self-Mastery Through Conscious Autosuggestion by Emile Coué PLUS The Practice of Autosuggestion by C. Harry Brooks.
Emile Coué was a French psychologist and pharmacist who introduced a new method of healing and self-improvement using the influence and power of auto-suggestion.
The application of his mantra-like conscious autosuggestion, "Every day, in every way, I'm getting better and better". Coué's method focuses on a routine repetition of this particular expression according to a specified ritual, in a given physical state, and in the absence of any sort of allied mental imagery, at the beginning and at the end of each day.
Self-Mastery fully details his method and explains how the concept of auto-suggestion works to bring about a desired circumstance. Although stressing that he was not primarily a healer but one who taught others to heal themselves, Coué claimed to have effected organic changes through autosuggestion.
