In opposing the Egregore, that claims to be the world, one does not reject the world itself but affirms it. What was transcended is only the lie. The world remains as it was, a mystery, but a mystery not impenetrable to the seeker.
If the Egregore is a thing, it is a thing only as a story is a thing. Or rather, humans' need of storying their happenstance: it calls forth story, it calls forth agreement. And it calls forth elaboration, which being inconsistent, leads to imperfect agreement. The story takes maintenance, or it fractures.
The truth of the Egregore is hidden, not because it is secret, but because it isn't.
