The experience of transcendence occurs within the nature of things -- our nature. A small mustard-seed grows into a tree big enough for birds to come and roost in its branches. To try to make it grow faster or slower would be absurd and counterproductive. It is the same when we experience the growth of Divine Love in our hearts as we let the husk of the ego drop away and like seed we die to self that we may fulfill the destiny that is our true meaning, that the potential of life within us may come to fruition.
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.
