ok, I've heard this enough to believe that there's some truth to it, on the other hand, there isn't much discussion after this. I mean, anyone who claims to have a "soul truth" or "divine knowledge" will carry with them the ultimate personal trump card that shuts down any investigation.
My personal sense is that you are either part of the community of inquiry who shares the vulnerability of the struggle to know, or you are a wanker who seeks to be highly thought of, but who has no authentic presence. There must always be discussion that flows from an assertion, opinion or revelation.
For me the only people who play trump cards (that's a term forever ruined for me - but I am buoyed only by the understanding that no trumps is better and purer hand) to shut down any investigations are those whose inauthenticity motivates that self-protective ploy. There is no legitimate excuse otherwise. I may decline to answer something you put to me, but I can never play coy and refuse to respond to something I triggered.
