You die - and this is why manmade religions don't work for so many of us. The notion that you're dead and that's the end, and they even try to contain you in coffins. They make them out of steel and stuff. But really, your journey - for all you know - is just beginning. For all I know, what you see now is just a tiny little seed. So, I may blossom into an entire - I don't know - something in the sky. Who knows where we're going?
