Pandu could not make love with his wives due to the curse by sage Kindama. A remorseful Pandu renounced the kingdom and went into exile with Kunti and Madri. He met some sages and asked them away for heaven and salvation. They said, without children, one can never aspire for heaven. When Pandu expressed to Kunti his despair at the prospect of dying childless, she mentioned the boon granted to her. He happily advised her to beget children by suitable, illustrious men. Thus, Kunti used the boon granted to her by Sage Durvasa (which she had used to bear Karna) to bear three sons—Yudhishthira by Dharmaraja - god of Justice; Bhima by Vayu - god of wind, and Arjuna by Indra - the king of Svarga (Heaven). She also invoked Ashvins for Madri on her behest and Madri gave birth to twin sons, Nakula and Sahadeva.
