“When our two souls stand up erect and strong,
Face to face, silent, drawing nigh and nigher,
Until the lengthening wings break into fire
At either curvèd point, — what bitter wrong
Can the earth do to us, that we should not long
Be here contented?”

"The Bat," ll. 5-10
Open House (1941)
Context: He loops in crazy figures half the night
Among the trees that face the corner light.
But when he brushes up against a screen,
We are afraid of what our eyes have seen:
For something is amiss or out of place
When mice with wings can wear a human face.

Ogni pelo arricciossi
E scolorossi al Saracino il viso,
La voce ch'era per uscir fermossi.

Context: Keep the faculty of effort alive in you by a little gratuitous exercise every day. That is, be systematically ascetic or heroic in little unnecessary points, do every day or two something for no other reason than that you would rather not do it, so that when the hour of dire need draws nigh, it may find you not unnerved and untrained to stand the test. So with the man who has daily inured himself to habits of concentrated attention, energetic volition, and self-denial in unnecessary things. He will stand like a tower when everything rocks around him, and when his softer fellow-mortals are winnowed like chaff in the blast.
