The Bhagavad-gita—Song of God—is a conversation between the military commander Arjuna and his friend and charioteer Krishna, before the onset of the historic Battle of Kurukshetra. Topics they discuss include the immortality of the self, the ultimate goal of life, the perfection of yoga, and the original relationship between the self and the Supreme Self.
The Gita appears as a central chapter in the epic Mahabharata, which chronicles the history of greater India up to the start of the current Kali-yuga, the "age of quarrel," circa 3000 BCE. Kurukshetra is now a district in the state of Haryana, India.
As the conversation begins, Arjuna is determined to walk away from battle rather than fight with those who had cheated his family of their kingdom. Krishna then instructs Arjuna on the difference between the self and the body, the essence of dharma—duty—and the ultimate goal of life. Krishna also reveals His identity as the Supreme Being, and explains how divine providence had already determined the outcome of the battle. Finally, Arjuna surrenders to Krishna's supreme will and decides to fight.
