The whole external world one has previously "passed through" is "in one", mapped onto the brain in areas one can only accidentally retrieve - perhaps that's a good thing, because those memories would constantly interfere with one's state, given the way the normal brain is continually making comparisons, associations, and noticing relationships, etc. Under the right circumstances, one can remember, or be made to remember one's very early childhood or even much earlier, and probably could be made to trace everything that happened from those days onward - clothes worn, other people present, furniture in that place, words spoken, feelings felt, etc.- and speak about them. But as one is ordinarily, one can NEVER be made to remember anything about Milan if one was never there, or Sydney, or Nome, because one was never there, and never watched movies or read books about them.
Same, of course, with "so-called" new ideas, which indeed are merely new places - not out there, but in here, being quite unfinished (site not located; foundation not poured) - though one does NOT have a clue where they might ultimately exist because the "map" has not been "encoded onto the new neural territory".
All words are in one. All ideas are in one. All possibilities exist for even ordinary humans, but few there be who can access the information directly. So they have to "share with each other" words, pictures, descriptions and subjective claims of what it all means, which is the way "those who supposedly know" try to remind other humans, of some "place" they've never seen, and never been, and may not even have suspected... but - as usual - the words, pictures, descriptions and claims of this as-yet-unknown location usually just distorts, if not even spoils the whole thing, making it even harder to grasp the "wholeness" that would otherwise be possible.
Sure, "teachers" MAY be able to convey the "suggestion" of this new, and apparently desirable "place", especially if they have in fact BEEN THERE and DONE THAT, though most never have, and are only "sharing" hearsay, from someone who got it all as hearsay themselves, who also got it as hearsay too. That is, the image and the reports they bring to you personally - "from their lips/fingers to your ears/eyes" - is so out of clarity/focus, in so many areas of the entire "place" that even if you were to struggle for years to figure out "what the hell they were talking about" - describing their memories of that place that was somehow constructed in their own heads - it would still only be a very poor representation of the reality of that wholeness.

Try to explain your childood- through teenage-years home in Milan, to someone on this list - take ten paragraphs if you need them - and NO ONE will have a clue what you are talking about, as that "place" could be anywhere on earth, but for a few nouns and verbs and adjectives you might have used. Same with [enlightenment, nirvana, consciousness - take your pick]. The internal locations of these large concepts (like Milan) are totally UNKNOWN to you or anyone because, in this case, Milan just happens to be on Jupiter. ("What, did I forget to mention that?")
That is, unless you are being TUTORED by a once or current RESIDENT of the ACTUAL NEURAL LOCATION, called "Milan" - having himself set down "roots", even if only temporarily, before moving on - you are getting something that is much less than worthless, as it may be incorrect as well, and you usually can NOT know this in advance. Imagine spending years trying to decipher a set of maps, diagrams, footnotes, and associated terminologies that, in fact, were totally made up and had nothing to do with anything useful to an aspiring human trying to actualize their Personhood.
Bottom line, though I could go deeper... Know Your Own Nervous System's makeup - its circuitry, functions, systems and processes - first and foremost, and forget the purveyors of hearsay who have NEVER BEEN THERE or DONE THAT, but nevertheless hold their hearsay in too high regard (that's just childish imagination!) in favor of finding Vacation Destinations within, that you can rightly value highly, due to your own personal visitations... AND such that you can revisit when desired, or totally leave behind when and if that suits you. (You can't leave a place until you know it.)
