Jealousy

1. There was once a king who was very jealous of the king of the neighboring country - whose kingdom was bigger than his, had more wealth and his people were more prosperous. One day he ordered to build a huge wall to stop the river that flowed through his land to the neighboring country. 
Result.... His own country got flooded and destroyed.

2. There was once a man who prayed daily to a particular god's deity that was placed among many other statues in the temple. One day, he noticed that the incense he lit for his deity drifted over all other statues as well. All of them were getting the benefit of his efforts! 
He built a paper cone over the incense burner so that all the fragrance would be directed only towards his favorite deity; right at the nose of the statue. 
Result:...too much and direct contact of smoke from the incense turned the face of his god's statue black.  

3. Once there was a rich man who had a big house in the city. But the next house – whose walls were adjoining to his house - looked bigger and more elegant than his house.
One night, the rich man set his own house on fire – hoping that the adjoining house of his neighbor will catch fire. 
Result … his own house was burnt and destroyed.
