Once there broke a war between the birds and the beasts. Many battles were fought one after the other. If vow the birds got the upper hand, the next time beasts were successful.

The bats played a very treacherous role in this war. They sided with whichever side got the better of the other. Thus they were changing their loyalty from side to side.

Neither side paid any attention to the bats till the war lasted. But when the war got over, the bats didn't know which side to go. First, they went to the birds. But the birds refused to own them as many birds had seen them fighting for the beasts.

Then, the bats went to the beasts. But there also they faced the same situation.

So, they were left all alone because of their disloyalty.

Once upon a time three sons were engaged in merchantile business under the supervision of their father. They were very rich. Each son was proficient in his own department.

If one was good in sales, the other one was competent in purchases and similarly the third one in finance.

Unluckily, one day the father got bed ridden and the sons decided to divide the business under the fallacy that each of them were experts in their own way and can handle their individual business solely.

The father was glum and grumpy with their decision but was helpless and unfortunately the separation took place.

As a result three of them became each other's competitors. With the passage of time, they started having huge losses in their respective businesses. They tried all possible ways to succeed but the situation became worse.

Then they came to their father for a piece of advice. The father said "when you all were doing the business jointly, the business ran successfully. But it was not any one of you responsible for the success of the business rather traits of all three of you put together made the business successful".

The sons realized their mistake & got reunited. So we conclude that disunity always ruins.
The End..
