Once upon a time, the son of Brahmadatta ruled righteously in Benares, in northern India. It came to pass that the King of Kosala waged war, killed the King of Benares, and took the queen as his own wife.
Meanwhile, the queen's son escaped through the sewers. 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 — demanding he surrender the kingdom or fight.
The prince's mother, the Queen of Benares, heard of her son's threat. She was a gentle and kind woman who wished to prevent violence, suffering, and bloodshed. She sent her son a message: "There is no need for the risks of battle. It would be wiser to blockade every entrance to the city. Eventually, the lack of food, water, and firewood will wear down 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, beheaded him, and delivered his head to the prince. The prince entered the city triumphantly and became the new King of Benares.
The moral is: Kind advice is wise advice.
