In the epic Mahabharata, Sanjaya, counsellor of the Kuru king Dhritarashtra, after returning from the battlefield to announce the death of Bhisma begins recounting the details of the Mahabharata war. Bhagavad Gita forms the content of this recollection. The Gita begins before the start of the climactic Kurukshetra war, where the Pandava prince Arjuna is filled with doubt on the battlefield. Realizing that his enemies are his own relatives, beloved friends, and revered teachers, he turns to his charioteer and guide, Krishna, for advice. Responding to Arjuna’s confusion and moral dilemma, Krishna explains to Arjuna his duties as a warrior and prince, elaborating on a variety of philosophical concepts.
The Bhagavad Gita is unique among religious texts in its emphasis on the discharge of everyday duties, irrespective of their nature, as an effective discipline for the realization of God. The Gita teaches that if a man performs his duties, surrendering the fruit to God and discarding all selfish motives, he gains purity of heart and achieves ultimate liberation. It is knowledge of God that gives man the strength to face calmly and cheerfully the duties of life. The Gita shows the way to spiritualize life and illumine even its drab and gray phases with the radiance of the Spirit. It lays down practical spiritual disciplines that can be followed by all, irrespective of faith and creed.
