How do we "know" and "feel" when the body falls away you seem to be asking? What if our brain and our mind are different? Say, our mind makes use of this complex chunk of stuff in our head(brain)while we live in our bodies, and the mind belongs to our spirit/soul just like our brain belongs to our body? (I might have read this somewhere years ago, don't know where.) These NDE experiences all seem to point that there is a part of us that is not flesh; that what the flesh occupies itself with(eating, etc) will not survive death, but that love(something our non-body self learns or does not learn to do) will survive the Great Journey. I probably confused the issue, and since I've never had an NDE, maybe should just keep learning from those who have made the Journey.
