brief note on space and sensations:
It can be tempting to "reify" "space" as such and "sensations" as such, to "feel space," to "point to sensations in space or in the body," the raw sensory experience as such, the shimmering/blinking "voxels," the "pixels" in extreme fine-grain detail.
Yes! Do this! if you’re drawn to it. This might be essential to do for at least a little bit. Let interest, intuition, meta-protocoling guide you. But, in some sense, "sensations as such" are no more/less real than chairs or tables. "Space itself" is is concept-laden, meaning-laden, and no more/less real than chairs or tables.
There are maybe subtle traps in "trying to make space real," "treating space as real," "pointing to things, extensions, volumes, manifolds" precisely in space or in the the body, and so on. This can lead to tangling, twisting, knotting. But a little bit of exploration like this (or a lot, depending on the person) can lead to untangling, untwisting, unknotting. It’s very contingent, what concepts, moves, etc., will be helpful, deliberate or spontaneous.
"Space" and "working with space" can be an excellent metaphor but is maybe not a good basis of practice. But for some people, some of the time, it might be a metaphor that very cleanly gives way to emptiness. It just depends.
And of course try to not to "reify" "reification," "inappropriate reification".....
(All of this pretty much applies to "time", as well.)
