There was a farmer. He had four sons. They were lazy and quarrelsome. They always quarrelled among themselves. So the farmer was very anxious about their future. One day he called his sons. He told them to bring a bundle of sticks. They did so. He then told each of his sons one after another to break the bundle of sticks. They tried but in vain.
Then the farmer told them to untie the bundle and break the sticks one by one. This time they could break the sticks easily. Then the farmer advised them by saying, " My sons live unitedly like the bundle of sticks. Then nobody can harm you." The sons realised their folly and promised to follow their father's advice. They lived together peacefully.
Moral : Unity is strength.
