Marriage to Pandu
Having just ascended the throne, Pandu went to war, conquering or allying with many kingdoms in the name of Hastinapur. When he approached Madra, he found a huge army waiting him. At parlay, he found himself taken aback by King Shalya's squire. Shalya revealed that the squire was none other than his own sister, Madri. He proposed that the two cities avoided war via marriage. Thus, Pandu married Madri.
Retreat to the Forest
She, alongside Kunti, faithfully accompanied Pandu in his hermitical retreat following his abdication as the king of Hastinapura. One day, while hunting in the forest, Pandu accidentally shot an arrow killing what he thought was a deer, but was actually the coupling Sage Kindama. The sage cursed Pandu that he would die when he became intimate with a woman. Both Kunti and Madri were directly affected by the curse on Pandu because they were now unable bear Pandu's children. However, a boon given to Kunti by Durvasa, enabled her to call upon any God to bear her a child. Accordingly, Kunti called upon Yama, Vayu, and Indra and bore Yudishtira, Bhima, and Arjuna respectively. This greatly relieved Pandu.
Birth of Children
Kunti agreed to share the mantras with Madri. Thus, Madri bore the twins Nakula and Sahadeva of the Ashwini Kumaras. At their birth, an incorporeal voice from the Heavens declared that the children would surpass their fathers in energy and beauty.
Death of Pandu and Self Immolation
On one fateful day, Pandu desired Madri and the memory of the curse briefly eluded him. As he pulled Madri into his embrace, death struck Pandu immediately. Madri, filled with remorse, went sati on Pandu's funeral pyre. Kunti became the mother of five children after the death of Madri.
