G.k. Chesterton said this quote
“ It's just because I have picked a little about mystics that I have no use for mystagogues. Real mystics don't hide mysteries, they reveal them. They set a thing up in broad daylight, and when you've seen it it's still a mystery. But the mystagogues hide a thing in darkness and secrecy, and when you find it, it's a platitude. ”
