Once upon a time there lived two crows, husband and wife on a tree. Every time, the wife hatched the eggs, a cobra would come and feast on the offspring. The couple asked a jackal who was their friend to show them the way. The jackal told them to go to a big city and snatch any item of jewellery from a palace and drop it in the hollow of the tree that is the cobra's home. In search of the jewellery, the king's men would reach the tree and kill the cobra. The crow couple flew off to a lake where the women in the king's harem were revealing in water. Before entering water, the women left their jewellery and clothes on the waterside. The female crow skilfully dived and snatched a gold necklace and began slowly flying towards the cobra's hideout. The king's men who saw the crow fly off with the necklace followed the female crow and saw it dropping the necklace into the hollow of the tree. They ran to the tree and pulling it out killed the cobra.

Moral
There is nothing that cannot be achieved with a trick.
