Fill your mind with all peaceful experiences possible, then make planned and deliberate excursions to them in memory. You must learn that the easiest way to an easy mind is to create an easy mind. This is done by practice, by the application of some such simple principles as outlines here. The mind quickly responds to teaching and discipline. You can make the mind give you back anything you want, but remember the mind can give back only what it was first given. Saturate your thoughts with peaceful experiences, peaceful words and ideas, and ultimately you will have a store house of peace producing experiences to which you may turn for refreshment and renewal of your spirit. It will be a vast source of power.
