The dervish and his BMW.

A dervish was leading a simple life in Paris. He did not really have personal
possessions, except for a BMW motorcycle. He was very happy with his BMW.
One day it so happened that he returned to the parking garage where he had left his BMW and saw that it was gone. He immediately started to reflect on it. He tried to see it as a test. He thought to himself: "Does it really
matter that I no longer have got it? Can I live without it?" He then realized that he did not mind at all and could live without his BMW. A minute or two later on he suddenly realized that he was standing on the wrong floor of the parking garage and he found his BMW easily by going to the correct floor.
