“I don't believe in an afterlife, so I don't have to spend my whole life fearing hell, or fearing heaven even more. For whatever the tortures of hell, I think the boredom of heaven would be even worse.”

From a letter to Tevis Clyde Smith (July 1925)

Context: I don't know if I'm closer to Heaven but
It looks like Hell down there.
These streets have never been paved with gold.

Song lyrics, The Ghost of Tom Joad (1995)

Que el cielo exista, aunque mi lugar sea el infierno.
"The Library of Babel" (1941)
Variants:
I cannot think it unlikely that there is such a total book on some shelf in the universe. I pray to the unknown gods that some man — even a single man, tens of centuries ago — has perused and read this book. If the honor and wisdom and joy of such a reading are not to be my own, then let them be for others. Let heaven exist, though my own place may be in hell. Let me be tortured and battered and annihilated, but let there be one instant, one creature, wherein thy enormous Library may find its justification.
May Heaven exist, even if our place is Hell.
"Deutsches Requiem". (Emece edition, 1974)

Variant: When I die I hope to go to heaven--whatever that is--and I want to be able to afford the price of admission.
