Dhritarashtra and Pandu were brothers. Dhritarashtra married Gandhari, and Pandu was
married to Kunti and Madri. King Pandu was cursed for a sin while hunting, due to which he was
not permitted to unite with his wife. Kunti got a boon through her sincere service of a wise sage in
her younger age, and she begot three children, namely, Yudhisthira, Bhima and Arjuna from Yama,
Vayu and Indra respectively. Madri had twins, Nakula and Sahadeva, through the celestial
physicians called Asvini-Devatas. Dhritarashtra had a hundred and one children by his wife
Gandhari. Pandu passed away and his sons, the Pandavas, were all brought up by Dhritarashtra
along with his sons known as Kauravas. The Pandavas and Kauravas grew up together, but due to
the braveness and intelligence of the former, the Kauravas were unable to tolerate them. Hence the
Pandavas decided to live separately, sharing half of their kingdom.
The Pandavas’ pomp, wealth and glory displayed during the Rajasuya Yajna aroused deep
jealousy and greed in the mind of Duryodhana, the chief of the Kauravas, who, with the cunning
advice of his uncle, Sakuni, invited Yudhisthira to a game of dice and fraudulently defeated him,
whereby all his wealth and possessions, including Draupadi, were lost. Finally it was settled that the
Pandavas, including Draupadi, should repair to the forest for twelve years in exile, after which they
had to live incognito for another year, untraced by the Kauravas. During this period the kingdom
was to be ruled by the wicked Duryodhana.
Having successfully completed these thirteen years of exile, facing many obstacles and
dangers instigated by the Kauravas, the Pandavas, as per the terms of the agreement, approached the
Kauravas for their share of the kingdom. Duryodhana, however, flatly refused to part with as much
land as could be covered by the point of a needle. According to the advice of Mother Kunti and with
the inspiration of Lord Krishna, the Pandavas decided upon war and tried to establish their rightful
claim on the kingdom by overcoming the Kauravas.
Duryodhana and Arjuna, from the side of the Kauravas and Pandavas respectively, were
sent to Dwaraka to seek the help of the Yadava hero, Lord Krishna, in the battle. They both found
Krishna resting on a couch in His palace. Duryodhana went in and occupied a seat at the head of the
couch while Arjuna stood near the feet of the Lord. The moment Sri Krishna opened His eyes, He
naturally saw Arjuna first, and then Duryodhana sitting on a chair. After enquiry of their welfare
and the purpose of their visit, Sri Krishna, according to the prevailing custom, gave the first choice
to Arjuna, because of his age, and also because of His sight of Arjuna first. Krishna asked Arjuna to
fulfil his desire by selecting Him unarmed or His powerful army called Narayani Sena. Arjuna, who
was a devotee of Sri Krishna, expressed his desire to have the Lord with him, neglecting the
powerful Narayani Sena, even though Krishna warned that He would remain a witness, bound by
the vow of not participating in battle and not taking up arms. Duryodhana, with great delight,
thinking that Arjuna was foolish, expressed his wish for the powerful army to help his side in the
battle.
When Krishna asked Arjuna why he chose Him when He was not for taking up arms, Arjuna
said, “O Lord! You have the power to destroy all the forces by a mere sight. Why then should I
prefer that worthless army? I have for a long time been cherishing a desire in my heart that you
should act as my charioteer. Kindly fulfil my desire in this war.”
