Hi svetamoscow,
I can understand the frustration. Do you have examples where the answer was given more clearly?
I know of Jed McKenna who spoke of 12 fully realized ones according to his insight and definition within 6 years in his system, which was something like finding the answer to the question "what is the truth?".
Also within yoga there are the terms savikalpa, nirvikalpa, sahaja and kaivalya. E.g. Gurunath is pretty precise in these and explains when which what in his book wings to freedom and also gives more details in his babaji book I am reading at the moment. He also gives names and speaks about their attainment and status, so lots of those you would say as of final realization are still on some grade in his mapping.
AYP has a 3 kind mapping, silence, energy, union. To my intuition if you have read Yogani's materials and what you read of those writing in the forums, the gap between him and lets say the second most advanced within AYP is quite huge.
Coming to your question and kaivalya, speaking of someone who is more precise in this and whose group I know within several countries (Gurunath), I'd say even though there are some crazily advanced guys who can for sure enter nirvikalpa samadhi already, to his mapping they are still kindergarten children. And if you experience his advanced students and him and compare, you can also see and experience, that it is so. According to his mapping he himself is only somewhere in the middle, lets say a "little" more advanced even though having attained kaivalya. (In my eyes he is among the most advanced available guys on this planet)
The better question perhaps would be, how many of which system have reached a state of "no problems, all is good, welcome to paradise" aka end of suffering, begin of happiness (=
According to Yogani this begins with the rise of witness. To my experience this also begins if the flow of life becomes paradise (two perspectives, one stillness, one movement). Surely if it is on both ends, this should get a mark in the roadmap (=
If you have the chance to ask others aswell, it would be nice if you could report back here. To my feeling a lot could be mapped and may surely happen more precisely. It is interesting, several hours ago I thought about translatig different languages, mappings into a unified system that can be used as a standard, like ISO or DIN
Yogani himself says, that 99%+ of the enlightenment topic is physical transformation, so it should be doable to quite some nice point. Other than that, till then, and that is good advice, one can already practice
All the other stuff in parallel (=
A question to you aswell, would you like to share the intention behind your asking? I think it is one of the most important questions, even though its answer may or may not satisfy
Peace and enjoy friend,
happy practice to all (=
