Once a great love cut my life in two.
The first part goes on twisting
at some other place like a snake cut in two.

The passing years have calmed me
and brought healing to my heart and rest to my eyes.

And I'm like someone standing in the Judean desert, looking at a sign:
'Sea Level'
He cannot see the sea, but he knows.

Thus I remember your face everywhere
at your 'face Level.'

Yehuda Amichai
