I go to AA meetings, and mostly I let the specifically religious stuff wash over me. I don't have a God, nor do I buy into a lot of the "there are no coincidences" stuff, nor the "cosmic force that orders the universe" either. But there are smart people, in meetings and elsewhere, who have experienced something worthwhile from their religious belief, and it's intriguing for me to try to make that meaningful for me, someone who doesn't have any particular belief in transcendance.
What really matters is just that process - sitting and carefully listening to others, trying to really pay heed to what they say, and shutting the f*** up for once in my life. It takes me out of my own self-centreness, which I soooooo badly need. It's not just learning, it's practising...
Otherwise, James Joyce: "God is a shout in the street" always worked for me.
