Ask much, the voice suggested, and I startled.
Feeling my body like the trembling body of a horse
tied to its tree while the strange noise
passes over its ears.
I who in extremity had always wanted less,
even of eating, of sleeping.
Agile the voice did not speak again, but waited.
"Want more"-
a cure for longing I had not thought of.
But that is how it is with wells.
Whatever is taken refills to the steady level.
The voice agreed, though softly, to quiet the feet of the horse:
A cup taken out, a cup reappears; a bucketful taken, a bucket.
