For me, spirituality includes the belief in things larger than ourselves, an appreciation of nature and beauty, a sensitivity to the world, a feeling of shared connection with other living things, a desire to help people less fortunate than ourselves. All of these things can occur with or without God. I do not believe in the existence of God, but I consider myself a spiritual person in the manner I have just described. I call myself a spiritual atheist. I would imagine that many people are spiritual atheists.
I don't try to imagine a personal God; it suffices to stand in awe at the structure of the world, insofar as it allows our inadequate senses to appreciate it.
I've been a musician since I was nine. I think a ghost or goblin visited me in the night. Maybe aliens abducted me, or a divine figure sent me a spiritual memo. Who knows.
