I am reading intently...

But I think you are projecting your own experience onto consciousness itself, in saying that, we need a school to ascend...

What about Jesus, Buddha, Osho, and various Holy Men and Shamans that learn from apprenticeship?  I think a school is necessary for socially minded individuals, which most people are, but it is definitely not necessary for all. 

I believe you may have said a great amount of luck can take the place of a school also, so this may be you referring to people like those I mentioned above.

And a relevant quote,

“I maintain that truth is a pathless land, and you cannot approach it by any path whatsoever, by any religion, by any sect. That is my point of view, and I adhere to that absolutely and unconditionally. Truth, being limitless, unconditioned, unapproachable by any path whatsoever, cannot be organized; nor should any organization be formed to lead or to coerce people along any particular path. If you first understand that, then you will see how impossible it is to organize a belief. A belief is purely an individual matter, and you cannot and must not organize it. If you do, it becomes dead, crystallized; it becomes a creed, a sect, a religion, to be imposed on others”  Krishnamurti

I'm not trying to make waves here, as I love making maps of consciousness, my own eclectic map is even very similar to the one you are describing [drawing much from Gurdjieff]  But one always should avoid straying into dogma [that they hold an "ultimate truth"] with their maps...
