The beeTvs are absorbed by the 顔 of Cain, who has marbles for 目(複). Doesn't like to use these lenses to look at the 世界. he prefers staring at the swirls inside, which he sees as a form of mineral poetry, incitement to action. Ask him any question, and he'll point there, for you to stare, as if you could see the same things there (as if you would really want to look there).
