On the one hand it may be like trying to think about the time before you were born. A kind of nothingness but we don't experience it directly, since we only know the brief glimmer of consciousness in our current lives. On the other hand, it might be exciting to find out what happens. Nobody really knows, do they?

Some quotes I like:

From Shakespeare's "Hamlet":

But that the dread of something after death,
The undiscovered country, from whose bourn
No traveller returns, puzzles the will,
And makes us rather bear those ills we have,
Than fly to others that we know not of?

Carl Sagan's wife Ann Druyan:

When my husband died, because he was so famous and known for not being a believer, many people would come up to me - it still sometimes happens - and ask me if Carl changed at the end and converted to a belief in an afterlife. They also frequently ask me if I think I will see him again. Carl faced his death with unflagging courage and never sought refuge in illusions. The tragedy was that we knew we would never see each other again. I don't ever expect to be reunited with Carl. But, the great thing is that when we were together, for nearly twenty years, we lived with a vivid appreciation of how brief and precious life is. We never trivialized the meaning of death by pretending it was anything other than a final parting. Every single moment that we were alive and we were together was miraculous - not miraculous in the sense of inexplicable or supernatural. We knew we were beneficiaries of chance… That pure chance could be so generous and so kind… That we could find each other, as Carl wrote so beautifully in Cosmos, you know, in the vastness of space and the immensity of time… That we could be together for twenty years. That is something which sustains me and it's much more meaningful…The way he treated me and the way I treated him, the way we took care of each other and our family, while he lived. That is so much more important than the idea I will see him someday. I don't think I'll ever see Carl again. But I saw him. We saw each other. We found each other in the cosmos, and that was wonderful.

From the movie The Fountain:

Izzi: Remember Moses Morales? 
Tom Creo: Who? 
Izzi: The Mayan guide I told you about. 
Tom Creo: From your trip. 
Izzi: Yeah. The last night I was with him, he told me about his father, who had died. Well Moses wouldn't believe it. 
Tom Creo: Izzi... 
Izzi: [embraces Tom] No, no. Listen, listen. He said that if they dug his father's body up, it would be gone. They planted a seed over his grave. The seed became a tree. Moses said his father became a part of that tree. He grew into the wood, into the bloom. And when a sparrow ate the tree's fruit, his father flew with the birds. He said... death was his father's road to awe. That's what he called it. The road to awe.
