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 till now. So something must have gone wrong in my spirit; I should no more handle the affairs of the state." It takes a long time to become fit, and it does not take a minute to become unfit. It is most difficult to collect the spirit and make it work as it ought to; the least little thing can upset it. Think of how many different parts must be made in order to make a watch go regularly, and how easy it is to drop the watch and destroy it.
