Arjuna Lays Down His Bow

Sanjaya said: Arjuna, having thus spoken on the battlefield, cast aside his bow and arrows and sat down on the chariot, his mind overwhelmed with grief.

At the end of Chapter 1, Arjuna — one of the greatest warriors who ever lived — puts down his bow. His heart is broken, his mind overwhelmed with sorrow. This is where the Gita truly begins: with a capable person unable to act because of emotional and moral confusion. Krishna will spend 17 more chapters answering this single breakdown.
