Thanks for the reference to David Hawkins' work in Kinesiology - I hadn't heard of him and to me Kinesiology has so far only related to food allergy testing and dietary/nutritional advice! There is obviously still much to learn!
You mention the duality of spirit and matter. Is it possible for these to be unified also? Would this be too paradoxical? Is it possible for us to be physical entities AND pure spirit simultaneously? Within Buddhism too there are disparities between theories of "emptiness". Is it possible to use meditation as a technique not to leave the body (as you put it) but instead to truly enter the body and realise what it is in "reality"?
Paradox seems always to be at the heart of these philosophies. Perhaps our paths to realisation are irrelevant at the end of the day, providing they each lead us to a shared destination which is truthful.
I suppose the fundamental questions remain "Who am "I"? and what does it really mean to "die" unto oneself while living?
best wishes
