There are many stories of how ancient people once lived an idyllic existence in some sylvan setting, where life was peaceful, plentiful, and pleasant. Ahh... there's nothing like nostalgia for the good old days! The Judeo-Christian myth along this line is about our once residing in the pleasures of the Garden of Eden, before we were evicted by the almighty landlord.
I have written before that there may well have been a historical setting for this garden of plenty: the Fertile Crescent of the Middle East. Once upon a time—several thousand year ago—the area was green and fecund and provided the people with plentiful sustenance, but the garden became over-farmed, the soil became barren and the area was transformed into a desert. We weren't expelled from the garden—we trashed it and then moved on.
There are somewhat similar Elysian stories about what happens after we die—that the glories of heaven await the faithful, who will bask forever in its splendor. It would be sort of like going back to the Garden of Eden in spirit—after having endured this vexatious mortal existence.
The dualistic perspective of the Abrahamic peoples posits an exact opposite of heaven as a place of eternal residence: hell. You've got only two conflicting and exclusive permanent destines: paradise or perdition.
What I find interesting is that human descriptions of hell are far more detailed than heaven. Every religion seems to possess a meticulous account of hell—a dismal, tortuous place where torment is everlasting. For example, Dante's The Divine Comedy is an epic 13th century poem describing an anguishing journey through the underworld. In contrast, heaven has only superficially been sketched by humans... streets of gold, the faithful reposing on clouds, or enjoying divine music, etc.
Why do humans put so much more attention to hell than heaven? I think it's possible that the story tellers (usually priests) wanted to frighten people into being good. Humans are very prone to wandering off the path of goodness and into the ditches of depravity. Most priests have found that, rather than paint heavenly scenes, the stronger prod is to scare the hell out of them.
If you think for a bit about heaven, however, doesn't it sound quite boring? If I were to laze around forever on cushy clouds, listen perpetually to any kind of music, or smile until my face cracked, I'd soon go berserk. What's more, it's the vicissitudes of life that really make it interesting. When things get too effortless, we become flabby and feeble. I would not want to go to the mythical heaven. Let me face affliction here and now, and be able to grow from it.
At the end of the day I don't fret over going to hell or look forward to heaven. I don't believe they really exist as our stories describe. It's our choice to live in heaven or hell (or a mixture), right here in this precious life. I think it makes more sense to put my attention to the here and now.
