A belief in the power to concentrate is of course very important. I purposely did not put this exercise in the beginning where it naturally belongs because I wanted you to know that you could learn to concentrate. If you have practiced the above exercises you have now developed this concentration power to a considerable extent and therefore you have faith in the power of concentration, but you can still become a much stronger believer in it.
We will say that you have some desire or wish you want fulfilled, or that you need some special advice. You first clearly picture what is wanted and then you concentrate on getting it. Have absolute faith that your desires will be realized. Believe that it will according to your belief be fulfilled. Never, at this time, attempt to analyze the belief. You don't care anything about the whys and wherefores. You want to gain the thing you desire, and if you concentrate on it in the right way you will get it.
A Caution. Never think you will not succeed, but picture what is wanted as already yours, and yours it surely will be.
Do you ever feel distrust in yourself? If You do, just ask yourself, which self do I mistrust? Then say: my higher self cannot be affected. Then think of the wonderful powers of the higher self. There is a way to overcome all difficulties, and it is a delight for the human soul to do so. Instead of wasting precious thought-force by dreading or fearing a disagreeable interview or event, instead devote the time and concentrated thought in how to make the best of the interview or event and you will find that it will not be as unpleasant as you thought it would be. Most of our troubles are but imaginary, and it is the mental habit of so dreading them that really acts as a magnet in attracting those that really do come. Your evil circumstances are created or attracted by your own negative, fears and wrong thoughts, and are a means of teaching you to triumph over all evils, by discovering that which is inherent within yourself.
You will find it helpful in overcoming self-distrust, to stop and think, why you are, concentrating your forces, and by so doing you become more closely attached to the higher self, which never distrusts.
