The Bhagavad Gita, The Song of the Bhagavan, often referred to as simply the Gita, is a 700-verse scripture that is part of the Hindu epic Mahabharata. It is a sacred text of the Hindus.

The Gita is set in a narrative framework of a dialogue between Pandava prince Arjuna and his guide Lord Krishna. Facing the duty to kill his relatives, Arjuna is "exhorted by his charioteer, Kṛiṣhṇa, among others, to stop hesitating and fulfill his Kṣatriya (warrior) duty as a warrior and kill." Inserted in this appeal to ksatriyadharma (heroism) is "a dialogue between diverging attitudes concerning and methods toward the attainment of liberation (moksha).

The Bhagavad Gita presents a synthesis of the Brahmanical concept of Dharma, theistic bhakti, the yogic ideals of liberation through jnana, and Samkhya philosophy.

Numerous commentaries have been written on the Bhagavad Gita with widely differing views on the essentials. Vedanta commentators read varying relations between Self and Brahman in the text: Advaita Vedanta sees the non-dualism of Atman and Brahman as its essence, whereas Bhedabheda and Vishishtadvaita see Atman and Brahman as both different and non-different, and Dvaita sees them as different. The setting of the Gita in a battlefield has been interpreted as an allegory for the ethical and moral struggles of the human life.

The Bhagavad Gita's call for selfless action inspired many leaders of the Indian independence movement including Mohandas Karamchand Gandhi, who referred to the Gita as his "spiritual dictionary".
