Good work Armand. Always an interesting area for speculation.
My musing is that IF consciousness turns out to be a/the fundamental ‘force’ of the ‘universe’ and matter, therefor, is relegated to just being a derivative of it, then it would be no stretch of the imagination to conclude that when the material body is sloughed off, consciousness remains.
It would be transformed though, because the material body acts as an anchor.
We get a feel for this each night when we lose contact with the stability of our body; our mind ‘takes up the slack’, and becomes an all encompassing world for us.
The Tibetans named the state after bodily death, but before rebirth, the ‘bardo of becoming’.
The overwhelming power of thought is the fundamental aspect of this bardo.
Without a physical body to anchor us, thoughts actually become reality.
"Our mind is so light, mobile and vulnerable here that we are completely exposed to the habits and tendencies we have allowed to grow and dominate our previous physical lives.The mental body (our vehicle in this bardo) is unable to remain still even for an instant. It is ceaselessly on the move. It is driven on by the ‘karmic wind’.
Lacking the father and mother essences of the physical body, we no longer have the light of the sun or moon. Only a dim glow illuminates the space immediately in front of us. We can see other bardo beings but cannot ordinarily be seen by the living.
The self-awareness we have in this state is said to be seven times clearer than in life. This can bring either great suffering or great benefit."
So to get a flavour of our afterlife, we should look at the overwhelming concerns and habits of our waking life together with the contents of our nightly dreams and crank them up to 11!
