In response to the poll: I voted "I don't know if there is life after death." I suppose it depends on the definition of life.
Nate, in response to your post (#9), I'd say those are great questions. I wish I knew the answers. If life is defined in a way that ties it directly to the body, the answer would obviously have to be no. But as you asked, is the body necessary for life? I just don't know. It might be that life does not exist after death, but perhaps consciousness continues.
In response to your post (#8), I don't interchange the words "religion" and "spirituality." To me, religion is a set of rules which devolves from an idividual's spirituality, and creates some worldly order (at best.) Spirituality, is to me, the idividual journey which sometimes gives rise to a religion.
I'm not sure religions offer much insight to this question, aside from pointing us in a general direction.
