You can make use of fear in two ways.
The one you use now is to run away when there is fear.
You believe in the logic of the ostrich and bury your head in the sand. How will you progress if you run from fear? Fear is an opportunity. The basic fear is that you might not exist! And if you are not prepared to annihilate yourself, how can God happen within you? There is no fear except death: Perhaps I might die and be no more! He who is unprepared to die cannot go into God or enter into prayer. The other possibility with fear is to surrender. Accept the existence of death; do not turn your eyes away from it. The day you encounter death with open eyes, you will see death disappear into oblivion. You had never come face to face with death, and therefore it existed for you. All fears of life flee in this manner if you face them in full awareness.
