Nothing to do with mystery cults, Mike - more to do with the arcanum. The mystagogue for me is a useful hook from which to suspend or relate to that occasional and often very relevant invasion of incongruency in my life experience. I'm personalising it in order to deal with it but it might be impersonal like gravity. Wittgenstein was wrong when he said - " Whereof one cannot speak,thereof one must say nothing."
