Unless we know, in a robust and reality-grounded way, what psychic experiences really are, and what true interplay with the realms beyond the material can look like, we’re going to have a hard time discerning how to navigate experiences at the edges of consensus reality.
The thing is, those experiences happen whether we want them to or not.
Even though as a culture we’ve become illiterate in the languages of the subtle realms, they are the basis for many of our experiences. (As an aside, our illiteracy here also fuels individual grandiosity in some of us who have altered or transcendent moments of awareness.)
This feels like a parallel with how things must have been like before we had a concept for microbiology.
