Darkness is Your Candle

What hurts you, blesses you. Darkness is
your candle. Your boundaries are your quest.
I could explain this, but it will break the
glass cover on your heart, and there’s no
fixing that.
You must have shadow and light source both.
Listen, and lay your head under the tree of awe.”
– from a poem by Jalal al-Din Rumi,  as interpreted by Coleman Barks
