Once there was a hunter. He was good at hunting birds. One day as usual, he placed a net for catching birds. After some time a group of doves were caught in the net. Every dove tried to free himself but in vain. A crow saw this. Crow was a symbol of unity. Unlike the dogs, the crows are always united. The crow then flew-down to the doves and advised them to make a united effort and fly away. They flew away carrying the net with him.
Moral: Unity is strength.
