As per the epic Mahabharata, the Pandava prince Arjuna and his brothers fought against their cousins, the Kauravas. In the battlefield of Kurukshetra, faced with moral crisis whether or not to fight against his own relatives and kill them for dharma (duty), Arjuna shared his reluctance to fight his near and dear ones with Lord Krishna, his charioteer, Who preached him about eternal and non-perishable nature of soul and revealed his virat-roop as a theophany , by endowing Arjuna with divine vision so that he was able to see the Cosmic form of the Supreme Being.
