'There are certain moments of looking at a familiar mountain which are unrepeatable. A question of a particular light, an exact temperature, the wind, the season. You could live seven lives and never see the mountain quite like that again; its face is as specific as a momentary glance across a table at breakfast. A mountain stays in the same place, and can almost be considered immortal, but to those who are familiar with the mountain, it never repeats itself. It has another timescale' (p. 50).
