On the battlefield, Arjuna refuses to fight his cousins, and Krishna teaches him about duty, action, devotion, and the nature of the self. The dialogue is embedded in the epic Mahabharata, but it stands alone as the most important text in Hindu philosophy. Gandhi read it daily. Oppenheimer quoted it at the atomic bomb test. The teaching is complex: act without attachment to results; all paths lead to the divine. The war will happen. Arjuna will fight. But the Gita is not really about war. It is about how to live when action is inescapable and consequences are uncertain.
