There is a story of a king who one day called a porter and gave him a command, and after having given that command he went into his room and signed his abdication of the throne. His wazirs asked him why he did this, what had gone wrong. He said, "When I was giving that porter a command I saw by his expression that it was not received in the same way as he had received my orders up until now. So something must have gone wrong in my spirit. I should no more handle the affairs of the state."
