As long as I'm collecting bits of wisdom on the unfathomable, here's one from Dream Song 366 (John Berryman): "These Songs are not meant to be understood, you understand. / They are only meant to terrify & comfort." (Which reminds me of this bit from City of Moths I read today, about "the sea": "She exists, I swear, I see her everywhere! She has been sent from somewhere far away to seduce and terrify.") And, to quote myself, from "Day Trip with Spires": "I don't want to apprehend the unknown."
