Sufi poetry has always been a favorite of mine. This particular one has always resonated with me. Perhaps it was due to growing up in a "dark" Lutheran(Garrison Keillor terminology lingo for you there) home.
Come, come, whoever you are
Wonderer, worshipper, lover of leaving.
It doesn't matter.
Ours is not a caravan of despair.
Come, even if you have broken your vow
a thousand times
Come, yet again, come, come.
