Creative Mind and Success, by Ernest Shurtleff Holmes [1919], at sacred-texts.com
THE way to give a treatment is first of all to absolutely believe that you can; believe that your word goes forth into a real creative power, which at once takes it up, and begins to operate upon it; feel that to this power all things are possible. It knows nothing but its own power to do that which it wishes to do. It receives the impress of your thought and acts upon it.
It is never safe to treat for anything that you do not wish to happen. This means that what you would want for another, you must first be willing to receive for yourself.
Believe then that your word is to be acted upon by an Almighty Power; feel its great reality, in and through all things you speak into it; and declare just what you wish it to do for you, never doubting in your own mind but that it will do just as you have directed.
All that a practitioner has to do is to convince himself, to know, to believe, and that thing will happen to him which he states. One of the first things, then, is to be definite; to have a mental likeness of the thing that you desire; to know exactly what you want. This mental likeness, this absolute acceptance of the fact that it now is, must never be overlooked; without it you will not accomplish.
We sit down of our own souls, at peace with the world, at peace with ourselves; we realize that we are dealing
with something that is a reality, something that cannot fail. We try to get a clear concept of the thing; we rest in that realization, while the Universal Creative Power takes it up and acts upon it.
We have stated just what we wanted done unto us; we have believed; we have believed that we have received; never again will we contradict the fact that we have stated. The person who can do this is sure of getting results.
