[Ishmael] listened to the world turned silent by the snow; there was absolutely nothing to hear. The silence of the world roared steadily in his ears while he came to recognize that he did not belong here, he had no place in the tree any longer. Some much younger people should find this tree, hold to it tightly as their deepest secret as he and Hatsue had. For them it might stave off what he could not help but see with clarity: that the world was silent and cold and bare and that in this lay its terrible beauty (Guterson, ch. 31)
