Song is not a luxury, but a necessary way of being in the world. If you are cut off, in pain, estranged, numb — sing, give voice to anything. It needn't sound pretty. Simply, bravely, open despite the difficulty, and let what is in out, and what is out in. Sing and your life will continue.
From the viewpoint of BELIEFS all doubts are disastrous. From the viewpoint of FAITH, doubt is the indispensable stimulant. To lose one's BELIEFS may not be a loss but a gain: an opportunity. "When the heart weeps for what it has lost, the spirit laughs for what it has gained," is an ancient Sufi saying. To lose one's FAITH, however, is catastrophic; the loss of this vital human constituent means mutilation, dehumanization, cynicism, nihilism.
