Although being new here, I may grok this topic enough to draw an analogy...
Maybe each Conscious Person, or more accurately, entity or being can perhaps be considered a loop on this chart.
If we consider ourselves the "one loop", then maybe we can consider the different versions of our higher selves as the "two loop" and so on into fully embedded systems.
Maybe this can illustrate the harmonic nature of multiple beings existing in an otherwise finite space.
Plus I think, maybe from our own Conscious Point Of View, the pattern continues in the opposite direction, where we are but one node on the "four loop", and we ourselves act as a "higher" being, much as parents offer support to their children. (Which may be both literal and figurative
) Though I suspect that we are unconscious of our contributions to this service most of the time....
Which I suppose is one goal of The Work to make ourselves aware of how we are contributing and participating in the systems of consciousness(s)
Though I am current Ignorant of the specifics of what is called 4d and 6d (and so on)as defined here, I suspect that maybe this analogy could be useful when viewing these concepts.
This comes to me via Akar's comments on Ra.
