You cannot stay on the summit forever. You have to come down again. So why bother in the first place? Just this: what’s above knows what’s below. But what’s below doesn’t know what’s above. One climbs, one sees, one descends, one sees no longer, but has seen. There is an art in conducting oneself in the lower region by the memory of what one saw higher up. When one can no longer see, one can at least know.
