Oh my, a perpetual dream state. Bliss I'd call it.
Really, Jews barely have a heaven, some sects believe in it, others simply have existence with GOD of a sort. They certainly don't have hell.
Christian dogma has created this concept of "eternal worship or returning to GOD" but it is poorly defined. The cartoonish characters are more amusing. St. Peter at a gate with a book checking names? Naughty or nice? GOD sounds a lot like an all-powerful Pope from the middle ages. We're all going to die and just sit there while he talks to us for all eternity.
Personally I believe in GOD but I can't see a reason to put any restrictions on it. My belief in Jesus has slipped substantially over the last few years, mainly because I don't see a reason for him. I've studied enough religions to realize that they're all essentially preaching basic empathy towards your fellow man, and then man perverts them into a way to gain material advantages over their fellow man.
Back to restrictions on GOD. I think that's my biggest turnoff to religion. Every restriction upon GOD has direct parallel to something we see in life. I have a customer that signs off his emails with the following:
"The cost of a big dream, a small dream, or no dream
is exactly the same: Why Not Dream Big!"
MY GOD IS TOO BIG FOR ANY DREAM
I think that's really nice and I wish more we would see it for what it is. Religion confines GOD, the one entity that is supposed to be without end or restriction, yet we restrict GOD by saying "GOD approves of __________" or "GOD disapproves of ___________", like really?
I can't define "heaven" because I can't define "GOD". I don't believe there are any books out there that do anything other than give guidance on being a decent human being.
I think a sort of reincarnation would be cool, like this is a starter world and you get to take all you've done and learned here and build on it in another dimension sort of. But really, who the
knows, but the classic Christian "I'm just gonna sit here for all eternity and be in GOD's presence" sounds rather droll.
