We all know that the Pandavas were five brothers. But very few people would know that the five Pandavas are not relatives but their mothers are different, Kunti and Madri. According to Dhritarashtra, Pandu was the manas of Ambalika and the son of sage Vyasa. He was the father of the Pandavas and the younger brother of Dhritarashtra. He had two wives, Kunti and Madhuri.
Pandu got a terrible curse: When Pandu did not become a father, he once went hunting. On the other side of the forest, under the illusion of a peacock, he shot an arrow that struck a sage. The sage was having sex with his wife at that time. While dying in this state, he cursed Pandu that he too would die if he had sex.
Unhappy Pandu: Saddened by the curse, Pandu told his Kunti that without children her life is useless. There are four debts on a person which he should pay off in his life. But without progeny, they cannot be freed from parental debt, sage debt, god debt and human debt.
Kunti gave birth to 3 Pandava sons: Kunti told her husband that the sage Durvasa was pleased and gave him a mantra by which he could invoke any deity and get a son. On receiving Pandu’s orders, Kunti first called the god of religion.
He got a son from the god of religion who came to be known as Yudhishthira. Then she invited the wind god and gave birth to Bhima. Indra, the king of heaven, called him again and took the form of Arjuna’s son.
Nakula became Madri and Sahadeva’s mother Pandu requested Kunti to initiate these mantras to Madri also. Kunti obeys her husband’s deity and teaches Madri also this mantra to get children. Madhuri called Ashwini Kumar with the mantra power and thus Nakula and Sahadeva were born.
