The whirlwind may arrange your will

garbandier:

…if you prosper, suspect those bright
Mornings when you whistle with a light
Heart. You are loved; you have never seen
The harbour so still, the park so green,
So many well-fed pigeons upon
Cupolas and triumphal arches,
So many stags and slender ladies
Beside the canals. Remember when
Your climate seems a permanent home
For marvelous creatures and strange men,
What griefs and convulsions startled Rome,
Ecbatana, Babylon.

How narrow the space, how slight the chance
For civil pattern and importance
Between the watery vagueness and
The triviality of the sand,
How soon the lively trip is over
From loose craving to sharp aversion,
Aimless jelly to paralyzed bone;
At the end of each successful day
Remember that the fire and the ice
Are never more than one step away
From the temperate city: it is
But a moment to either.

But should you fail to keep your kingdom
And, like your father before you, come
Where thought accuses and feeling mocks,
Believe your pain; praise the scorching rocks
For their desiccation of your lust,
Thank the bitter treatment of the tide
For its dissolution of your pride,
That the whirlwind may arrange your will
And the deluge release it to find
The spring in the desert, the fruitful
Island in the sea, where flesh and mind
Are delivered from mistrust.

[Alonso to Ferdinand, in The Sea and the Mirror by W. H. Auden

The Sea Hates a Coward
