Again, not really anything new here but something that is coming to the foreground again…
Whenever there is resistance, there is a split of space itself.
There is a field of 3D space, with sensations, sights, sounds and so on arising within (and as) it.
And some particular sensations in the upper neck/lower head area are used as an anchor for a sense of a separate I. These sensations seem denser than the rest of the field (the rest is space & sometimes form), and there is a sense of tension there.
With this as an anchor for a sense of I, other forms in the field can be made into Other, and when they are, there is also a resistance towards these. The space is split up into I here and Other there, and there is a sense of boundary, limitation, contraction, narrowing, tension and precariousness (I don’t know if the boundary can be maintained, or what will happen if what is on the other invades this side or the other way around.)
In daily life, this is very tangible, and a very good help in noticing what is going on. As soon as the space appears as less than infinite, in any direction, or as soon as some part of the field appears as dense, I know that there is a resistance, an identification with a particular identity.
And in allowing it all, including what is on the other side of the boundary and the boundary/resistance itself, the sense of vast space again arises. There is a release of identification with just a segment of the field, and so a release of being caught up on one side of the boundary and the other side arising as Other.
