With a changing key, you ...

With a changing key, you unlock the house where the snow of what’s silenced drifts. Just like the blood that bursts from Your eye or mouth or ear, so your key changes. Changing your key changes the word That may drift with flakes. Just like the wind that rebuffs you, Clenched round your word is the snow.
 Paul Celan

Quotes from the same author

Poetry is perhaps this: an Atemwende, a turning of our breath. Who knows, perhaps poetry goes its way—the way of art—for the sake of just such a turn? And since the strange, the abyss and Medusa’s head, the abyss and the automaton, all seem to lie in the same direction—is it perhaps this turn, this Atemwende, which can sort out the strange from the strange? It is perhaps here, in this one brief moment, that Medusa’s head shrivels and the automaton runs down? Perhaps, along with the I, estranged and freed here, in this manner, some other thing is also set free?
 Paul Celan
German poetry is going in a very different direction from French poetry.... Its language has become more sober, more factual. It distrusts "beauty." It tries to be truthful.
 Paul Celan
