After Bhima was born, Kunti using the mantra, prayed to Lord Indra, giving birth to a son, named Arjuna.
Madri felt dejected and envied Kunti, as she had her own children. She expressed herself in front of Pandu, who requested Kunti to share the mantra with Madri. Kunti kind-heartedly taught Madri the mantra.
Madri using the mantra, invoked the Ashwini Kumaras, giving birth to twins, Nakul and Shadeva.
Years later, on a fine spring day, Pandu forgot about the curse received by Sage Kindama, and embraced his wife, Madri. No sooner he touched her, he died.
Kunti, being the first wife, had to follow her husband’s path, and asks Madri to look after the children. But Madri refused as she might not be able to love the children equally like Kunti. Saying this, she leaves her sons, Nakula and Sahadeva in the care of Kunti, and jumps into the funeral pyre of Pandu, performing the act of Sati. Before Dying, Madri asked yudhisthira to take care of her siblings, like their father.
Helpless, Kunti returned to Hastinapur along with her 5 children.
