I was recently introduced to the Jewish idea of soulmate called bashert, at a theatre production of the rather bizarre "Clean House". After poking around on the web, I found the following description from an article on JewishJournal.com:
"A Jerusalem rabbi once told me that when we're born, God whispers the name of our beshert -- our soulmate or destiny. The cleft above our lips, he said, is where God places a finger, to silence our ability to reveal the secret."
Rather lovely I think.
