Yes indeed, people don't want to die to go to heaven, because they believe, that they are a body and that they are living.
We are not bodies, but pure universal Mind, that is dreaming that it is a "body". There is no death, because there is literally no life outside of heaven. That's the point.
In other words: We are also not a body lying somewhere sleeping and dreaming - we are no body at all. Universal Mind is Spirit. That's hard to grasp, when everyone seems to believe, that they are a body - it seems to be "normal" to believe that. That's why it's called an illusion.
The ego part of the Mind (and Mind is not a part of a "brain" - a "brain" is part of the Mind instead) does everything to cover this up - simply for the reason, that once you realize this, you always have the option to choose "the right minds" view and the ego fears that it loses the trust in it, which is experienced as a fear of "death". Since the ego is no alive at all, it's not really a death though...
This realization alone, changes the whole perspective of "life". It's radical.
I hope, I could explain this very important point better.
