Fear is illusory; it cannot live. Courage is eternal, it will not die. Perils, calamities, dangers are the certain lot of every man who is a denizen … - Sivananda Saraswati

For prayers and meditation, you can have any comfortable position. You must select a fine pose in which you can sit for a long time comfortably. The only condition is that your neck and back should be erect. Close your eyes, breathe in and out very slowly and mentally repeat the Mantra OM OM OM and think of the divine qualities of the Lord. Now you will enter into silent meditation. You will enjoy great peace and acquire inner spiritual strength. (Avoid Extremes in Yoga)

Practice the virtue during the day. Feel that you actually possess courage to an enormous degree. Manifest it in your daily life. In some weeks or months fear will be replaced by courage. Repeat the formula “Om courage” mentally, daily several times.

A man of courage does not tremble in the hour of danger. He is not embarrassed and bewildered. He does not sink down. He is not overwhelmed by despair... He smiles away all dangers and difficulties, blows the trumpet of triumph and attains victory in the end.
