To know the difference,

you must run this mountain without pause. In the evening or the afternoon, you must cross the first fields waking
to your footsteps, stormwashed at the foothills.

In the evening or the afternoon, in the closing of a shadowline, you must read aloud the reddened last words of this canyon's leaves to the trees that clap their hands.
