" Memory is igneous more than ingenious, igneous, and like granite, intrusive, heaved up within oneself, the whole range of one's life, mountains' forbidding height looming over the plains where one lives, mountains formed by the life already lived, but toward which one is always walking, one's own past ahead of him, seeking the improbable path already forged, this path back through oneself, this path we call the present tense, which becomes the continental divide when the tense shifts and the path is lost, path from which the walker emerges only to turn around and see the peaks pulled up by his feet, and the snowy pass, and alpine heights, where those stranded must sometime feed on themselves to survive, where sometimes, through the icy crust, the crocus blooms.
