Gita, short for Bhagavat Gita, the Divine song is a philosophical dialogue in the Mahabharata. The setting is the start of the great war between the Kauraqvas, and the Pandavas. Arjuna, the Pandava hero, finds himself ranged against his elders, close kin, friends and teachers. The thought of the piercing them with his arrows disturbes him deeply.
Distraught, he breaks down, throws away his bow and declares that he will not fight. There, in the middle of the Kurukshetra, Krishna counsels his friend about life as well as his duty as a warrior so that he can fight the war with full moral conviction.
