Have you noticed how no two people have exactly the same idea of what Heaven is like. With Hell there's even more variance, including those who believe in heaven but not in Hell at all. After all, Hell only features large in one sect of one particular religion, and one can't help thinking that it's used in the same way as parents might have coerced their children to behave by threatening that the bogeyman would take them away if they did not do this, or did do that. No logic - just do as I say, or else...
I really struggle to see the point of Heaven. If it is an existence free from physical constraints, then there can be no individual physical sensation, no contrast, and therefore no appreciation of bliss. Would we become passive, incapable of doing anything that we had done whilst alive on Earth? Or would we experience virtual pleasure and pain as if it were real . (Could this apparent present physical body be a part of that experience - not real, but giving every impression of being real, in order to achieve its purpose?) If so why? How does make any difference to anything? We just go on existing because we exist. We achieve nothing, in eternity. Personally I find the idea of 'not being' after death a far preferable outcome. It has the benefit of certainty and if one does not exist one will not miss what it is to exist anyway.
I can understand from a psychological point of view why Heaven would originally have been such a comforting concept, when lives were generally short and brutal, and there was no chance to change one's lot. Heaven would give one hope, provide a purpose for our misery, provide comfort in our distress, give meaning to our otherwise apparently pointless lives.
But wishing that something were true does not mean that it must be true. Parsimony would suggest that there is no need for Heaven; and that therefore it does not exist.
I just wish I could understand how it is that so many humans are prepared to suspend logic and indulge in this untenable wishful thinking? Is it brainwashing? Is it the Ego refusing to countenance non-existence? It must be something very compelling - though most likely ultimately false.
