NEVER CHALLENGE THE NATURE
Once an eagle came flying and sat on the branch of a tree that stood by a pool. At that time, a tortoise was basking on the bank of the pool. He was very dissatisfied with his life on the ground. He wanted to fly in the air like birds. So, he wished the eagle and said, "Sir! I have to make a request."
The eagle asked, "What it is?"
The tortoise said, "Please teach me, how to fly. I am fed up of my life on ground."
The eagle advised the tortoise not to go against the rule of nature, as she hasn't given you wings to fly. But the tortoise didn't listen to him and requested so hard that the eagle had to agree to teach him flying.
So, the beagle picked up the tortoise in his claws and flew high in the sky. The tortoise felt puffed up. Suddenly, the eagle let him go. Down came the tortoise to fall head-long on a rock and dashed to pieces.
