Continuing on from 'Consider some stuff', we can inquire further about the nature of stuff.
Since it's infinitely inclusive, my choices (and everyone else's) necessarily are 'made of' this one-stuff, whatever it is.
As well as the brain matter that facilitates (filters and frames the range of) choices.
Once again, one-stuff can't be excluded from all that occurs, otherwise it wouldn't be one-stuff that is the ground of all.
btw, one-stuff is perhaps a poor description. It might better be described as one-process, or one principle.
Which ultimately validates the Theory of One and All, with both sides being interdependent, and inter-penetrating, like individual and community; hand and body, wave and particle, finite and infinite.
One-stuff or "one-process" is both and all at once.
Since we're all made of this one-process, we are both physical while being meta-physical beings, with latent potentials that span to the infinite (since we can't be entirely disconnected or separate to all, including the infinite).
