I'm not sure if IQ is exactly the right term, but I definitely think making your way to a place like this, seeing, understanding, and valuing the accounts of mystics, and valuing the premise mysticism presents, is a function of intelligence.
I remember growing up, panegalli, intuitively understanding the premises of mysticism. I would be in the classroom and think to myself, "this is all pretend right?" or "this is like Plato said, we're in the shadow world or the false world, this isn't reality itself" or "as above, so below; just like we can play a virtual reality computer game, so too my existence in this body is the same."
I was constantly trying to find someone who perceived things in the way I did (I particularly hoped for an attractive young lady to think the same haha) but I found no one shared my views.
I remember when I studied philosophy in college, how far it went off-topic. In an academic setting I don't even know what "philosophy" means. Plato and Socrates were very clear philosophy was a preparation for death, that philosophy purified and elevated the soul, and that the goal of the philosopher was to separate from the corrupt body and to return to Reality.
And don't get me started about religious people haha. It is interesting how universal religion is, that it is inherently human to value it and have a sense of the spiritual. But how it is interpreted is amazing.
I find the symbolism of Christianity very heroic myself. Of Christ, the god-man and Crucified One (as Teresa called him), calling the Christian to forsake the body and embrace the life of the spirit. Yet this call isn't followed by any Christian I know. Particularly here in America Christians are so far removed from the life-negation and self-transcendence of Christ it is astonishing. They do none of the aid to the poor, sick, alienated or imprisoned. I expect most of these Christians will find themselves making their way right back here again.
So, I definitely get what Jeff is getting at when he says "IQ." It is certainly a faculty of intelligence to value these topics and come here. And, the fact your Inner Director brought you here is evidence you have what Jeff describes.
