I think the poem is not
Transparent, as some have said, not a looking-glass,
as some have also said,
Yet it has almost the quality of disappearance
In its cage of visibility. It disperses among the words.
It is fluidity, a vapor of love.
— Hayden Carruth, from “The Impossible Indispensability of the Ars Poetica,” What Will Suffice: Contemporary American Poets on the Art of Poetry, ed. by Christopher Buckley and Christopher Merrill (Gibbs Smith, 1995)
