Measure the days you have left. Do just that labour
which marries your heart to your right hand: simplify
your life to one emblem, a sail leaving harbour
and a sail coming in.

Derek Walcott, Omeros

For Once, Then, Something
Robert Frost (1874–1963).
(First published in Harper’s Magazine, July 1920.)
OTHERS taunt me with having knelt at well-curbs
Always wrong to the light, so never seeing
Deeper down in the well than where the water
Gives me back in a shining surface picture
Me myself in the summer heaven, godlike        
Looking out of a wreath of fern and cloud puffs.
Once, when trying with chin against a well-curb,
I discerned, as I thought, beyond the picture,
Through the picture, a something white, uncertain,
Something more of the depths—and then I lost it.        
Water came to rebuke the too clear water.
One drop fell from a fern, and lo, a ripple
Shook whatever it was lay there at bottom,
Blurred it, blotted it out. What was that whiteness?
Truth? A pebble of quartz? For once, then, something.        

Pebbles and marbles, like things on my mind
Seem to get lost and harder to find
When I am alone, I am inclined
If I find a pebble in sand
To think that it fell from my hand

from Pebbles and Marbles, Phish
