A long, long time ago, there was a kind old man who lived on the plains outside the Great Wall of China. The gentle old man had only two passions in his life: collecting rare breeds of horses, and his son, whom he loved more than anything else.
The old man and his son would ride their horses every day. They would travel great distances to trade horses, meet new people, and enjoy the good fortune that life had bestowed upon them.
One morning, a servant left the stable door open and one of the old man’s favorite stallions escaped. When the neighbors heard the news of the stallion’s escape, they came to comfort the old man. They told him they were sorry he had had such bad luck.
But strangely enough, the gentle old man was not upset. He explained to his neighbors that losing the horse wasn’t necessarily bad luck. There was no way to predict that the horse would escape, it just happened, and now there was nothing that could be done about it. “There is no reason to be upset,” said the old man. The neighbors soon realized that there was nothing they could do to help get the horse back, and that they shouldn’t feel sad for the old man’s misfortune.
One week later, the stallion came back, and he brought with him a mare. This was not just any mare, but a rare and valuable white mare. When the neighbors heard of the old man’s good luck, they quickly came to congratulate him. But again, the old man was not excited. As he had explained before, it was not necessarily good luck that had brought him this new and beautiful white horse. It just happened, and there was no reason to get excited over it. Still a bit puzzled, the neighbors left as quickly as they had come.
A short time later, while his son was riding the white horse, she slipped and fell. She landed on the son’s leg, and broke his leg, so that he would always walk with a limp. Again, the neighbors came to the old man’s house to give their sympathy for the bad luck that had befallen his son. One of the neighbors suggested that the old man sell the mare before anymore bad luck could happen, and others said that he should take his revenge and kill the mare. However, the old man did neither. He explained to the neighbors that they should not feel sorrow for his son, nor anger towards the mare. It was purely an accident that could not be predicted, and there was nothing he or they could do to change it. At this point, the neighbors thought the old man was crazy and decided to leave him alone.
Two years later an enemy invaded the country, and all of the old man’s neighbors were drafted to defend the country against the attack. Because the old man’s son was lame, he did not have to join in the fighting. The war was very bad, and most of the old man’s neighbors were killed, but his son was spared because he had been hurt by the white horse two years earlier.
