Mr Yin of Chou was the owner of a large estate who harried his servants unmercifully, and gave them no rest from morning to night. There was one old servant in particular whose physical strength had quite left him, yet his master worked him all the harder. All day long he was groaning as he went about his work, and when night came he was reeling with fatigue and would sleep like a log. His spirit was then free to wander at will, and every night he dreamt that he was a king, enthroned in authority over the multitude, and controlling the affairs of the whole State. He took his Pleasure in palaces and belvederes, following his own fancy in everything, and his happiness was beyond compare. But when he awoke, he was servant once more. To some one who condoled with him on his hard lot the old man replied: ‘Human life may last a hundred years, and the whole of it is equally divided into nights and days. In the daytime I am only a slave, it is true, and my misery cannot be gainsaid. But by night I am a king, and my happiness is beyond compare. So what have I to grumble at?’
Now, Mr Yin’s mind was full of worldly cares, and he was always thinking with anxious solicitude about the affairs of his estate. Thus he was wearing out mind and body alike, and at night he also used to fall asleep utterly exhausted. Every night he dreamt that he was another man’s servant, running about on menial business; of every description, and subjected to every possible kind of abuse and ill-treatment. He would mutter and groan in his sleep, and obtained no relief until morning came. This state of things at last resulted in a serious illness, and Mr Yin besought the advice of a friend. ‘Your station in life,’ his friend said, ‘is a distinguished one, and you have wealth and property in abundance. In these respects you are far above the average. If at night you dream that you are a servant and exchange ease for affliction, that is only the proper balance in human destiny. What you want is that your dreams should be as pleasant as your waking moments. But that is beyond your power to compass.’ On hearing what his friend said, Mr Yin lightened his servant’s toil, and allowed his own mental worry to abate; whereupon his malady began to decrease in proportion.
