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.
Rumi said that all words are fingers pointing to the moon, and we think the words are the moon. But because of the light, the light of love, the energy and motion that have called us to prayer, bits of this deeper reality are perceivable, and little bits of it will have to do.
