Swift Things are Beautiful

Swift things are beautiful:
Swallows and deer,
And lightning that fall
Bright-veined and clear,
Rivers and meteors,
Wind in the wheat,
The strong-withered horse,
The runner's sure feet.

And slow things are beautiful:
The closing of day,
The pause of the wave
That curves downward to spray,
The ember that crumbles,
The opening flower,
And the ox that moves on
In the quiet of power.
