This is called "The Darker Powers."
"Even if you're right, and there's
in fact a difference between trouble unlooked-for,
and the kind of trouble we pursued, ruthlessly,
until at last it was ours.
What will the difference have been, finally?
What I've called the world continues to pass for one,
the room spins same as ever, the bodies inside it do,
flightless, but no less addicted to mastering--
to the dream of mastering--
the very boughs through which they keep
falling without motion, almost, that slowly.
It seems they'll fall forever, my pretty consorts,
to whom sometimes--
out of pity, not mercy, for nothing tender about it--
I show the darker powers I've hardly shown to anyone.
'Feel the weight of them,' I say, before putting them back,
just behind my heart, where they blacken and thrive."
