I dont think much changes when you die. We are a part of everything out there what we see and understand, what we dont. Look at all the the relationships we have to the universe as humans.

We need the air, we need the sun, we need food, we need water, we need each other. What we dont need directly is needed by those things we need - and on and on and on.

So if we are part of this great universe in need of all these things how is it we no longer need anything after we die?

So to me we carry on completing our role whether in a body or not.
