Unity is strength/Farmer and his sons

Once an old farmer had four sons. They always quarrelled [ঝগড়া] with one another. One day the old farmer called his sons and told them to bring some sticks and tie them in a bundle. He told them to break the bundle. They tried but could not break the bundle of the sticks. Then he told them to untie the bundle and gave a stick to each sons and asked them to break it. Then all of them broke the stick easily. The farmer told them that if they would remain separate and quarrel with one another, the enemy would easily defeat them. But if they remained united like the bundle, they would be much stronger and the enemy could not do any harm to them. At this, the sons learnt a great lessons and began to live unitedly and happily.
