Hasn’t it been shown that our brain neurons extend far beyond the mindReferring to stuff like this - https://www.hopkinsmedicine.org/health/wellness-and-prevention/the-brain-gut-connection
I guess I am not understanding exactly what you r doing when you (with the physical universe being your starting point) “work back to the mind from that central perspective”.Purely evolutionary stand point. It started with star dust in a particular of a galaxy, that created a particular kind of solar system the created a particular kind of Earth Moon partnership that created the most fantastical gem in the Universe. We have coding in our body that's been handed down billions of years and hundreds of millions of years, folds within folds of cumulative harmonic process, cascading down Time, everyday bringing small and big changes, that join the cascade as time marches on.
Fractals, think fractal and responding to the environment you find yourself in, be you amoeba, bug, critter or mammal or primate or human or dolphin.
All I am is dancing on top of that until I and my gods melt back into it.
And then there’s dealing with my day to day to the best of my abilities.
Does any of that make sense?
Does that help?
