As the two armies stood face to face on the battlefield, Arjuna suddenly looked at the opponents and realised that he was up against the people whom he loved and respected the most-Bhisma, Dronacharya, and Kripacharya. Even if he won, his victory would be sad. With all these doubts in mind, he put his bow and arrow down. Krishna, who was not only Arjuna's chariteer but also his guide, understood what Arjuna was thinking. He delivered a sermon on Karma , and the immortality of the soul. He told Arjuna that the one who dies fighting loses his temporary body but his soul finds a seat in heaven. He told that it was Arjuna's duty to fight. This sermon became renowned as the Bhagavad Gita. Hearing this, Arjuna's doubts were removed and he was ready for battle.
