This Katha was narrated by Pulastya Muni to Sage Narada. In the Treta Yuga there lived a King named Krtavirya. He was a very powerful and famous king. But the king had no son to inherit the kingdom and the King was worried about the future of his people after his death. So he decided to go to forest and do tapas and other austerities to please Lord Vishnu. Krtavirya’s wife, Padmini, came to know about her husbands intentions and decided to go along with him. The king made an ashram near Sage Atri and started performing austerities but he was not able to please Lord Vishnu. A worried Padmini then consulted Sage Atri’s wife Anasuya. She advised her to observe two ekadasis falling in the Adhika Masa. Krtavirya and Padmini then observed the two Ekadasis falling in Adhika Masa
