The Bhagavad Gita, often referred to as simply the Gita, is a 700-verse Hindu scripture in Sanskrit that is part of the Hindu epic Mahabharata (chapters 2340 of the 6th book of Mahabharata). The Bhagavad Gita is a Bhagavata explanation of the Purusha Sukta and the Purushamedha Srauta yajna described in the Satapatha Brahmana. The Gita is set in a narrative framework of a dialogue between Pandava prince Arjuna and his guide and charioteer Lord Krishna. Facing the duty as a warrior to fight the Dharma Yudhha or righteous war between Pandavas and Kauravas, Arjuna is counselled by Lord Krishna to fulfill his Kshatriya (warrior) duty as a warrior and establish Dharma. Inserted in this appeal to kshatriya dharma (chivalry) is a dialogue ... between diverging attitudes concerning methods toward the attainment of liberation (moksha) . The Bhagavad Gita was exposed to the world through Sanjaya, who senses and cognises all the events of the battlefield. Sanjaya is Dhritarashtra's advisor and also his charioteer. The Bhagavad Gita presents a synthesis of the concept of Dharma, theistic bhakti, the yogic ideals of moksha through jnana, bhakti, karma, and Raja Yoga (spoken of in the 6th chapter) 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 (soul) 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.
