I am catholic, although not very religious; the truth, I have become a bit skeptical over the years. But I find it comforting, when we lose a loved one, the idea of something after we leave the earthly plane, what is that something, I think we will not have the answer, but maybe we become some energy, in another plane. And I do like @joanstewart's idea of Star Dust, as well.
Way I want to go, 'waste not want not', Star Dust makes the most sense to me.
Yeah I find it very comforting as well to believe that we go to a happy place after this. The whole there is nothing idea is a bit too depressing to me...
