I first gained an interest in this theory in the past because I heard that a man of off-the-charts IQ 195+ (Christopher Langan) had developed a theory regarding the universe itself. I found myself truly incapable of understanding his technical jargon and what his theory really meant, but I think that I suddenly got a slight insight into what he meant.
While it is not really a theory that talks about the meditation experience itself, his theory supports multiple levels of consciousness, reincarnation, a universe observing itself, God, etc.
I'll just post one TINY abstract of what he has here:
http://www.teleologic.org/SCSPL - According to the Reality Principle, the universe is self contained, and according to infocognitive monism, it regresses to a realm of nil constraint (unbound telesis or UBT) from which it must refine itself. According to the Telic Principle, which states that the universe must provide itself with the means to do this, it must make and realize its own "choice to exist"; by reason of its absolute priority, this act of choice is identical to that which is chosen, i.e. the universe itself, and thus reflexive. I.e., "existence is everywhere the choice to exist." Accordingly, the universe must adopt a reflexive form in which it can "select itself" for self-defined existence, with the selection function identical to that which is selected. This means that it must take a certain general or "initial" form, the MU form, which contains all of the requisites for generating the contents of reality. Due to hology, whereby the self-contained universe has nothing but itself of which to consist, this form is self-distributed.
His full paper is here:
http://www.megafoundation.org/CTMU/Articles/Langan_CTMU_092902.pdfThe full paper is extremely difficult to read though. I find his conclusions pretty interesting.
The strangest thing is that many people are beating him down for his paper, saying it contains psychobabble and that he is not a qualified physicist (as he dropped out in high school due to a scholarship problem). He is not presenting it as a support for theism nor atheism though, it's strange as to why there is such a violent reaction, saying that this paper is theistic when it obviously it about the universe observing and affecting itself, deciding on its own existence, being one with mind.
Also, his Q&A regarding reincarnation, etc -
