This is the childhood story of Yudhishthir, the hero of Mahabharat. He is the one who first established the city of  Indraprastha, i.e. present Delhi.

In his childhood, Yudhishthir had lost his father and was required to come with his mother and four younger brothers to stay with his uncle Dhritarashtra, the great emperor of Hastinapur. He soon became known for his wisdom, humility, truthfulness and love for justice. People of Hastinapur came to look upon him as their future king . Even Dhritarshtra was obliged to declare him as the heir apparent in preference to his own son Duryodhan who was younger to Yudhishthir.

However, both Dhritarashtra and Duryodhan  were unhappy in their  hearts over this arrangment. They both thought that if somehow Yudhishthir died, and that too with his mother and brothers, then Duryodhan could become heir apparent.
