A certain dervish was travelling through the desert, and stayed the night in the camp of another dervish. He was shocked to see the luxury of his host's tent--soft beds, colourful hangings--and most shocking of all were the solid-gold tent pegs. He upbraided his host:
"You call yourself a holy man? We must make a pilgrimage to Mecca, so you can purify yourself."
His host said, "Very well, let's leave at once," and began to walk. The traveller said, "--but aren't you going to pack up your belongings? What about those tent pegs?"
"They are driven into the ground, not into my heart."
So I was feeling quite excited and pleased with myself as I arrived at the book shop...and saw a sign on the door about how they're not buying any books for the next week because their manager is away.
It just goes to show, I suppose, that it's possible to attach to anything, even the idea of getting rid of stuff.
