According to the epic poem Mahabharata, Krishna becomes Arjuna’s charioteer for the Kurukshetra War, but on the condition that he personally will not raise any weapon. Upon arrival at the battlefield and seeing that the enemies are his family, his grandfather, and his cousins and loved ones, Arjuna is moved and says his heart will not allow him to fight and kill others. He would rather renounce the kingdom and put down his Gandiv (Arjuna’s bow). Krishna then advises him about the nature of life, ethics, and morality when one is faced with a war between good and evil, the impermanence of matter, the permanence of the soul and the good, duties and responsibilities, the nature of true peace and bliss and the different types of yoga to reach this state of bliss and inner liberation. This conversation between Krishna and Arjuna is presented as a discourse called the Bhagavad Gita.
