hi, I'll chime in with my view on death and what part of us moves on.
suppose you have a cup of water, it is in a cup but the cup isn't water - only that which is contained within the cup is water. Now imagine taking that cup of water and pouring it into the ocean - you can no longer tell what was your "cup of water" and what was the ocean, because they merge together and become one. the water doesn't retain the shape of the cup and stay together in that compilation without the separation brought about by the container.
I think what we are is the ocean and each of us as individuals are in containers of identity (ego's), but when its time to leave the container we merge again and are one without any separation or distance. The cup (body & ego) end they cannot merge.
