Climbing poem

This is a poem about climbing, which I think there are few of. I found in a climbing book, I thought it applied in other situations. Perhaps it partly explains why anyone would put themselves through such torture to reach the top.

One cannot stay on the summit forever -
One has 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 -
One desends and sees no longer -
But one has seen!

There is an art of conducting one´s self in
the lower regions by the memory of
what one saw higher up.

When one can no longer see,
One does at least still know.
