the bundle of sticks
The farmer had several sons who always argue with each other.The farmer tried many times to get the boys to cooperate,but they would not.One day the farmer decided to teach them a lesson.He put a bundle of sticks in front of the brothers.One by one,brothers tried to break the bundle,and each failed.Then,the father untie the bundle and gave them the sticks to break one by one.
The brothers broke them easily."Learn from the example,"the father said"Together you are as strong as the bundle.Dvided,you are as weak as the sticks.'
In unity there is strength.
