Story of the Mahabharata
In the north of India, there flourished a kingdom with its headquarters at Hastinapur. King Pandu was ruling the kingdom after his father's death, as his elder brother, Dhritarashtra, was born blind and therefore not qualified for the rulership according to the tenets of that age.
King Pandu had five sons who were known as Pandavas. Dhritarashtra had one hundred sons who were called as Kauravas, the eldest of whom was Duryodhana. Bhishma was the uncle of Pandu and Dhritarashtra.
After Pandu's death his children, Pandavas, were brought up and educated along with Kauravas under the supervision of Bhishma and patronage of Dhritarashtra. Drona was a skillful teacher who taught them all the techniques of warfare. Pandavas were intelligent and brave. Within a short time they could master the art of warfare. Yudhishtira, the eldest of the Pandavas, succeeded his father as the king.
Duryodhana was jealous of the Pandavas. When Yudhishtira was proclaimed a king Duryodhana could not keep quiet and watch. He employed all foul means to destroy Pandavas and every time he tried to kill them he met with failure. On Bhishma's advice the kingdom was divided into two parts - the better one with Hastinapur as capital was taken by the Kauravas while the Pandavas took the other half and built a new beautiful capital called Indraprastha for themselves.
Dhritarashtra was equally affectionate towards his sons and Pandavas but had the weakness to be sympathetic towards his eldest son's sorrows and disappointments.
Once Duryodhana invited Yudhishtira for a game of dice wherein the former with the help of his cunning and deceitful uncle, Sakuni, defeated Yudhishtira by using all fraudulent means. As a result, Yudhishtira lost not only all his kingdom and possessions but also Draupadi, the wife of all the Pandava brothers. Draupadi was humiliated by the Kaurava brothers to such an extent that an attempt was made to disrobe her in public. Her honor was saved by Bhagavan Sri Krishna, a great family friend of the Pandavas.
Finally it was settled that Pandavas should live in the forest for twelve years in exile and further one year incognito untraced by any one. After successfully completing these thirteen years of ordeal when the Pandavas claimed their kingdom Duryodhana refused to part with even that much little land as could be covered by the point of a needle.
The good offices of Sri Krishna to bring sanity to Duryodhana who was intoxicated with power and greed proved futile. The Pandavas were left with no alternative but to take up arms against Kauravas to regain their kingdom lost through tricks, treachery and chicanery.
A war between Pandavas and Kauravas became inevitable and the preparations for the epic battle started. Both the sides mobilized their troops and took their respective positions in the battlefield at Kurukshetra, near modern Delhi.
Bhagavan Sri Krishna was the charioteer of Arjuna, the mightiest of the Pandava brothers. Arjuna asked Sri Krishna to place their chariot between the two armies to enable him to have a glimpse of all those with whom he had to fight. Although till that time he was in full fighting spirit, when he saw his teachers, elders, brothers, relatives and friends standing before him ready for the fight, his determination gave way to weakness of head and heart. He lost his enthusiasm to fight and told Sri Krishna that he did not want to wage the battle against his seniors, relations and friends for the sake of a paltry kingdom.
When Arjuna refused to fight, Sri Krishna gave him a good peace of advice enlightening him upon where his duty lay. This marvelous advice delivered by The Bhagavan in the battlefield at Kurukshetra is the immortal poem, the song divine, the glorious SRIMAD BHAGAVAD GITA which epitomizes the whole gamut of knowledge contained in all the Scriptures.
Sage Vyasa offered Dhritarashtra the power of sight which would enable him to see the events of war. Unwilling to see the inevitable massacre of his sons, the blind king desired to know the full details of the war. To fulfill Dhritarashtra's request Vyasa bestowed Sanjaya, the trusted minister of Dhritarashtra, with the divine intuitive vision by which he could know not only the incidents of the battlefield but also the ideas in the minds of the warriors.
After ten days of war, Bhishma, the commander of the Kaurava army was severely wounded and thrown off his chariot. When Sanjaya informed Dhritarashtra about this incident the blind king became very sad and asked him to tell him all the details of the war. The reporting of Sanjaya about the events of war including the dialogue between Sri Krishna and Arjuna at the battlefield is contained in the Bhishma Parva of Mahabharata wherein The Gita text finds place. The Gita opens with the question of the blind king to Sanjaya asking him what happened on the battlefield when the two armies faced each other in the battle formation.
