Yeah agnostic means you're nor atheist nor religious. You just don't know. I feel that way I think. The universe, it's complexity, the coherence of all physics: I would not state there is nothing. I just think none of the religions on earth have the answers let alone the institutions that represent them.
I still remember the first time I heard the suite of the Transition album. It gave me a very special feeling. There was something emotional happening with me. Same thing with Dearly Beloved on Sun Ship. I'd like to call that a spiritual experience.
