Faith is not a belief. Faith is what is left when your beliefs have all been blown to hell. Faith is in the heart, while beliefs are in the head. Experiences, even spiritual experiences, come and go. As long as you base your faith on experience, your faith is going to be constantly flickering, because your experiences keep changing. The moment you recognize that faith lies behind experience, that it's just being, but the experience of being, then it's just "Ah, so".
~ Ram Dass from Be Love Now
