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.

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 conflict it is always imagination that triumphs.
