After ten days when the sweets were finished she went back to the healer and said, "I would give anything if you could let me have some more of those sweets. They were wonderful." Then the teacher said, "My friend, you must understand after eating the sweets for ten days, that your husband, having toiled all day, is nervous and tired and weary when he comes home. Naturally he is not in tune; and you made him worse by talking. By keeping silent you gave him nothing to quarrel about, and your home became more harmonious. This should teach you a lesson: that silence is the key to harmony.'
