  • Here is how a man once talked with his house.
    'Please, if you're ever about to collapse,

    let me know.' One night without a word the
    house fell. 'What happened to our agreement?'

    The house answered, 'Day and night I've been
    telling you with cracks and broken boards and

    holes appearing like mouths opening. But you
    kept patching and filling those with mud, so

    proud of your stopgap masonry. You didn't
    listen.'


    - Rumi, 'Ghazal 1134', version by Coleman Barks with Nevit Ergin in 'The Glance'.
