There probably are higher dynamics, though I'm not fully convinced of it yet.
Pilot gives his list of them as being harmonics of sorts of the lower ones, CaptBill gives some of his while some higher ones are kept confidential, Filbert had his shot at them too.
What they are is still an open question. A good part of the problem here is that above the 8th Dyn you are entering an area where language as we know it starts to break down and meanings and English words no longer correlate very effectively.
And it's not about "survival" up there - more like something to do with "participating in creation" or "being aligned with the creative urge". Even here already words are inadequate.
What all of this comes down to is, as I said, that above 8th Dyn you're in a realm where language disintegrates ans no longer functions well. So the more asserted and pontificating rightness you encounter on what goes on up there the more likely is is that you are dealing with some version of bullshit.
Best is that you get up there and determine for yourself what goes on. Develop your own paradigms and "languages" and don't be too concerned if they don't align with what other people say.
FWIW Leon, I like your attitude ... there's even a (albeit unlikely) possibility of learning something from you ... off I flit now, I have lots of pretty butterflies to chase.
