"I am one of you and being one of you Is being and knowing what I am and know. Yet I am the necessary angel of earth, Since, in my sight, you see the earth again, Cleared of its stiff and stubborn, man-locked set And, in my hearing, you hear its tragic drone Rise liquidly in liquid lingerings, Like watery words awash; like meanings said By repetitions of half-meanings."
