follow As the battle draws close, Arjuna is overcome with self-doubt about the righteousness of the war against his own kith and kin. He is distraught at the thought of having to fight with his friends and family such as his dear teacher, Drona and grandsire Bhishma. It was then that Krishna took charge and explained the necessity and inevitability of the war to Arjuna. This conversation is a key part of the Mahabharata known as Bhagavad gita, and is considered as a holy scripture of Hinduism. Arjuna plays the role of the reader in the Bhagavad Gita. As Krishna dispenses the advice, Arjuna asks the questions. The Bhagavad Gita primarily takes the form of a philosophical dialogue between Arjuna and Krishna.
