you won't ever experience "Focus 27", "the library" or any pre-defined place in the non-physical exactly how someone else has defined it.
So, don't bother asking if any of these places exist, because we can only tell you our perspective of it. Instead, try to experiment and make your way there yourself... then you'll have turned something from a belief into a KNOWN. *THAT* is your goal.
I think you got me wrong on this one. I know this "place" exists (I was there). And I just dropped this question here because ...
First, I was indeed (only) interested to find out how (as you say) "someone else has defined" and located libraries in general - in literature, in certain models, approaches and views of reality (old and modern). I know well that all these models (planes & bodies, focus, vibrational frequency, dimensions, etc.) are just approaches by different individuals and cultures to describe, 'road-map' or'categorise' non-physical reality.
The thread is after all called 'been to F27', so this is what we do here, too - making categories and "maps" for our experiences, phenomena, etc. - yeah, an almost impossible task, I know. But it is also fun, isn't it?
So secondly, if s.o. says that F27 might include libraries, then I can answer: "yes, probably I was there .. because I was at a library" - thread purpose fulfilled.
Therefore I asked if the model says that library/libraries is/are placed there (I think they are, btw.), so I can give a rough assessment as to I've been to what some call F27... or not.
