This is a poem called "Circle of Struggle"
The book has an epigraph from Rilke which I'll read.
It's from one of the Duino Elegies.
And it goes in one translation.
"For beauty is nothing but beginning of terror
was still just able to bear.
And why we adore it so is because it serenely
disdains to destroy us."
Satchel Paige somewhere has a series
of six rules for staying young.
I think the sixth one goes, don't look back,
something might be gaining on you.
