The father in "The Bundle of Sticks" taught his sons an important lesson on unity. When he noticed that his sons were always quarrelling among themselves, he applied wisdom (the quality of applying good judgement, experience, and knowledge in handling matters) by using a bundle of sticks to teach them an important lesson on unity.
He gave them a bundle of sticks to break individually which they were unable to do. But when he gave them each of the sticks from the bundle, they successfully broke them. He thus taught them that when they are unified no challenge or enemy can overcome them.
