Not only do people come from different backgrounds, experience - intelligence? imagination? but language itself depends upon common referents. What to do - when you need a new referent? in order to try to pass on [something].

Hence, the (concentric) 'circles' in all such enterprises:

exoteric outsiders or newbies.
mesoteric somewhat initiated, transitional.
esoteric inner-circle, local 'leaders' by whatever name.

Believe that a failure to comprehend this rather necessary org. plus (for some? many?) an inability to discern a simile from a report, a metaphor from a 'documentary' -- and an allegory from a lengthy tale:

For the various levels being all-intermixed, within all holybooks.. it's no wonder what the record is for Popular religious orgs. - perpetual misunderstanding of what is meant ergo perpetual internal / external wars. op. cit. 'history'. Confusing a 'teaching parable' with an actual historical event, a creation myth for a calendar of events... well, we see what happens, and how many will kill to be Right. Ignorance Kills.

So re your query, Brett
I know no way around the necessary experience of life and of the varieties of human ego / human use of language as a means for men to disguise their thoughts from each other - and the discernment to tell which is which: when what you think you want to know is, simply Everything. (And if one also imagines it can all be set out in a book, or a library - like a Unix manual... well)

Luck indeed but: I wish you also - a considerable amount of drudgery, discarding of previous mental clutter, and enough will to pursue (quietly thus with no 'need' to share 'discoveries'!) over decades.. Too tough? Then - forget it and just mouth the words, for comfort. 'Earnestness' means: willingness to 'work'.

Cheers,
