What is the story of the "five books" of Indian story literature?

The five-volume Bunsen Sutra is two treasures of Indian story literature. These two books mainly contain fables, one compiled by a Brahmin scholar and the other by a Buddhist. The Five Classics tells that a king gave birth to three sons, all of whom were ignorant. The king invited a Brahmin to teach the prince all the strategies of governing the country, moral norms and the way of the world within six months. Five volumes are textbooks written by Brahmins for princes.
