A Reward - Denise Levertov

Tired and hungry, late in the day, impelled

to leave the house and search for what
might lift me back to what I had fallen away from,
I stood by the shore waiting.
I had walked in the silent woods:
the trees withdrew into their secrets.
Dusk was smoothing breadths of silk
over the lake, watery amethyst fading to gray.
Ducks were clustered in sleeping companies
afloat on their element as I was not
on mine. I turned homeward, unsatisfied.
But after a few steps, I paused, impelled again
to linger, to look North before nightfall-the expanse
of calm, of calming water, last wafts
of rose in the few high clouds.
And was rewarded:
the heron, unseen for weeks, came flying
widewinged toward me, settled
just offshore on his post,
took up his vigil.
If you ask
why this cleared a fog from my spirit,
I have no answer.
