Which three lines or phrases from this excerpt of her poem "Poetry" does Marianne Moore use to show the impact of great poetry?

I, too, dislike it: there are things that are important beyond all this fiddle.
Reading it, however, with a perfect contempt for it, one
discovers in
it after all, a place for the genuine.
Hands that can grasp, eyes
that can dilate, hair that can rise if it must,
these things are important not because a
high-sounding interpretation can be put upon them but because
they are
useful. . .
