The Song of the Bhagavan, often referred to as simply the Gita, a 700-verse Hindu scripture that is part of the Hindu epic Mahabharata. It is set in a narrative framework of a dialogue between Pandava prince Arjuna and his guide and charioteer Krishna. Facing the duty as a warrior to fight the Dharma Yudhha or righteous war between Pandavas and Kauravas, Arjuna is counselled by Krishna to "fulfill his Kshatriya (warrior) duty as a warrior and establishing Dharma."
