Have you ever drifted off to sleep, but before you did, you had a rush of images and sounds from all around you? It felt like everything was still very vivid and in your last moments of conciousness, you were able to register and comprehend everything that went on...That might be what death is like, only thousands of times more intense...If we did indeed die and assimilate with The Big Guy, it WOULD be everything we want. God IS everything and we would become one with everything. God doesn't have to give us motorcycles or tits to play with, for we have trancended all need and want. We would trancend all being and identity...This would also be nirvana.
Yes I think it is also true that we probably cease to exist, but the feeling of oneness and wholeness is not fleeting by any means. I think it is important to live your life to the best of your ability, as when you die, you don't get a second chance. Your atoms will eventually be reconsituted within other living beings, but you will never again be the whole living organism you are now.
Obviously this is all just me writing down my thoughts.
