Just to piggyback on this post:
It sums up how I feel about the afterlife, and theological discussions, or at least, the absence of theological discussion.
Reincarnation is an interesting idea; it's sort of cleverly cruel form of social control. Instead of driving home an idea of an eternal suffering elsewhere, it drives home that if you're bad, you wind up right back in your misery, or worse.
