He went crying straight to his mother. Her heart melted at her son's eyes. She gave him a gold coin. When the father asked his son what he had earned, the son presented him the gold coin. The father asked him to throw it into a well. The next day, he asked his son to earn something. This time he went crying to his sister who gave him a coin. When he showed it to his father he again asked him to throw it in a well. Then the father asked him to earn more money.

He did so and sweated plenty. As he returned home he was asked to do the same. The son almost cried out. He could not imagine throwing his hard-earned money like this. He cried, "My entire body is aching. You are asking me to throw the money into the well." At this moment, the businessman told him one feels the pain only when the fruits of hard labour are wasted.
