A pearl

There was a very odd American man I met in Athens who said I had a lovely endearing smile. After several late night chats he showed me a massive tattoo on his abdomen. Not particularly a beautiful tattoo, it was a Persian poem, written in Arabic script. He proceeded to recite the poem- I can't remember it exactly, but something about a man travelling the world searching for a pearl only to realise at the end of his journey the pearl he was looking for was within himself.

I've been searching for the poem since.
