Contrary to the generally accepted theory the will is not the invincible force it is claimed to be; in fact, whenever imagination and will come into … - Émile Coué

People may wonder why I am content to prescribe such a general and apparently vague formula as "Every day, in every way, I am getting better and better" for all and every ailment. The reason is, strange as it may seem, that our subconscious mind does not need the details. The general suggestion that everything "in every way" is going well is quite sufficient to set up the procedure of persuasion which will carry its effects to the different organs and improve every function. I have had remarkable demonstration of this in the course of my long teaching and experiments. Time and again I have seen patients cured, not only of the particular disease for which they sought relief, but also of minor disabilities which they had almost forgotten.

Self-mastery is attained when the imagination has been directed and trained to conform with our desires-for although, in one sense, the imagination is inclined in the subconscious, yet it dominates the latter, and therefore, if we know how to guide it, our subconscious self will take charge of our material being and do its work just as we wish it to be done; or, in other words, exactly in conformity with our conscious suggestions.

Translation: Every day, in every respect, I'm getting better and better.
