You cannot stay on the summit forever; you have to come down again… So why bother in the first place? Just this: What is above knows what is below, but what is below does not know what is above. One climbs, one sees. Once descends, ones sees no longer but one has seen. There is an art of conducting oneself in the lower regions by the memory of what ones saw higher up. When one can longer see, one can at least know.
