From “Work,” a poem by Mary Oliver, from the book “The Leaf and the Cloud.”

“I will sing for the veil that never lifts.
I will sing for the veil that begins, once in a lifetime,
   maybe, to lift.
I will sing for the rent in the veil.
I will sing for what is in front of the veil, the
    floating light.
I will sing for what is behind the veil –
   light, light and more light.

This is the world, and this is the work of the world.”
