Once upon a time, the son of Brahmadatta was ruling righteously(正直地，公正地) in Benares, in northern India. It came to pass(实现，发生) that the King of Kosala made war, killed the King of Benares, and made the queen become his own wife.
Meanwhile, the queen’s son escaped by sneaking away through the sewers(下水道) . In the countryside he eventually raised a large army and surrounded the city. He sent a message to the king, the murderer of his father and the husband of his mother. He told him to surrender the kingdom or fight a battle.
The prince’s mother, the Queen of Benares, heard of this threat from her son. She was a gentle and kind woman who wanted to prevent violence and suffering and killing. So she sent a message to her son — “There is no need for the risks of battle. It would be wiser to close every entrance to the city. Eventually the lack of food, water and firewood(柴火，木柴) will wear down(磨损，使疲劳) the citizens. Then they will give the city to you without any fighting.
The prince decided to follow his mother’s wise advice. His army blockaded the city for seven days and nights. Then the citizens captured their unlawful king, cut off his head, and delivered it to the prince. He entered the city triumphantly and became the new King of Benares.
The moral is: Kind advice is wise advice.
