A child responds to the game of kissing away a hurt or throwing away a fear. This simple process works for the child because in his mind he believes that that is actually the end of it. The dramatic act is a fact for him and so it proves to be the end of the matter.
Imagination is a source of fear, but imagination may also be the cure of fear. “Imagineering” is the use of mental images to build factual results, and it is an astonishingly effective procedure. Visualize your fears being drained out of your mind and the visualization will in due course be actualized. Imagine yourself as reaching into your mind and one by one removing your worries.
However, it is not enough to empty the mind, for the mind will not long remain empty. It must be occupied by something. It cannot continue in a stat of vacuum. Therefore, upon emptying the mind, practice refilling it. Fill it with thought of faith, hope, courage, expectancy.
A half-dozen times each day crowd your mind with such thoughts as those until the mind is overflowing with them. In due course these thoughts of faith will crowd out worry. Day by day, as you fill your mind with faith, there will ultimately be no room left for fear.
