This is a Sufi Story from the Middle East, the original can be found here
Mula came upon a frowning man walking along the road to town.
“What’s wrong?” he asked.
The man held up a tattered bag and moaned:
“All that I own in this wide world barely fills this miserable, wretched sack.”
“Too bad,” said Mula, and with that, he snatched the bag from the man’s hands and ran down the road with it.
Having lost everything, the man burst into tears and, more miserable than before, continued walking.
Meanwhile, Mula quickly ran around the corner and placed the man’s sack in the middle of the road, where the man would have to come upon it.
When the man saw his bag sitting in the road before him, he laughed with joy, and shouted: “My sack! I thought I’d lost you!”
Watching through the bushes, Mula chuckled: “Well, that’s one way to make someone happy!”
To quote Joni Mitchell in Big Yellow Taxi:
“Don’t it always seem to go,
That you don’t know what you’ve got
‘Till it’s gone”
Appreciate what you have.
