Rainer Maria Rilke - The Panther (Mitchell trans.) lyrics

His vision, from the constantly pa**ing bars, has grown so weary that it cannot hold anything else. It seems to him there are a thousand bars; and behind the bars, no world. As he paces in cramped circles, over and over, the movement of his powerful soft strides is like a ritual dance around a center in which a mighty will stands paralyzed. Only at times, the curtain of the pupils lifts, quietly--. An image enters in, rushes down through the tensed, arrested muscles, plunges into the heart and is gone.
