Panchatantra story-The greedy jackal
Long time ago there lived a lazy jackal. Also in the hills there lived a hillman and a wild boar. One day when the hillman went to hunt, he saw the wild boar. He took a sharp aim with his arrow and stuck the boar. But the boar was only injured and it attacked the hillman and he died on the spot. Later the boar also collapsed due to the injuries and died.
The jackal happened to pass the site of both the dead bodies and the bowstring, and the jackal decided to eat them slowly. But he was excessively greedy and first wanted to eat the bowstring, before the other bodies. As he tried to eat the bowstring which was tightly attached to the bow, it snapped and the end of the string pierced its mouth and the jackal died on the spot.
Story moral: Too much of greed is harmful.
