In order to arrive at what you are not,
you must go through the way in which you are not.
And what you do not know is the only thing you know,
and what you own is what you do not own,
and where you are is where you are not.
— T. S. Eliot, from “East Coker,” The Four Quartets. (Faber & Faber 1959) Originally published 1943.
