Union is strength.

Once there lived an old man. He had four sons. They always used to quarrel with one another. He advised them to live in peace. They did not care for it. The old man was very sad and depressed. He wanted to teach them a lesson. He thought of a plan. One day he gave them a bundle of sticks. He asked them to break it one by one. They tried their best to break it but failed to do so. Then he asked them to untie the bundle. He gave one stick to each of them and asked them to break it. This time, they broke it very easily. He advised them to live together like the sticks which were in bundle and not breakable and when they were untied, they were broken easily. Now his sons got it and they never quarreled again.
