Stab and Grab: Anchoring Portals to a Barrier
Stab and Grab, they could simply be about anchoring portals to a barrier. On image A, once a vortex penetrates through a barrier, it becomes a portal and can no longer wander sideways. Previous posts have covered the "bite-across" as an anchoring symbol, and stabbing through a neck with a sword or spear seems equivalent.
Then I found paws and feet marked with knives and scorpions, crabs and crayfish and now I'm thinking those grabby pincer arthropods are simply functioning as foot grabbers, to anchor a portal symbol. Hands are portal symbols, even without a stigmata (which re-inforce the portal through a skin barrier meaning), and when a spike is present, that seems to reinforce the meaning even further to where a flow connection is anchored.
The horizontal bar on image C represents the barrier between our-reality and a higher-density/dimension like heaven. So portals to heaven anchored with spikes could be the meaning. The sorrowful heart on image I would tell us that many flow connections involve the core of the torus, and they are anchored through the core barrier.
It also turns out that ancient languages use "transfix" for stab, where to "fix" is to hold in place. Crucifixion also has the fix meaning to anchor. In other languages, crab is even more related to "grab".
