I think a fundamental problem here is the assumption that
information is an essential tool. For science it is, but not
necessarily elsewhere. Seems to me that in things like
shamanism, skills are far more important than info. It's
a combination of intuition and experience, none of which
needs to be articulatable(?). Shamans (The Shamen is
something else -- well, partly!) are not inducted by being
given books to read, they are initiated by being put
through an experience. They don't gain information so
much as change their personalities. How to put that
into words? Impossible, I'd guess. And precisely the
same applies to all mystical-type stuff. No amount of
information can substitute for experience.
