Background
Seven hundred verses spoken between two armies, in the pause before the first arrow. Arjuna asks the questions any honest person would ask; Krishna answers across eighteen chapters that move from grief, through duty and action, to devotion.
This chapter is the longest in the library by a wide margin, and it approaches the Gita through the people around it — Arjuna, who cannot lift his bow; Bhishma, bound by a vow made for someone else's happiness; Drona, a teacher on the wrong side; Karna, who knows the truth of his birth too late to act on it; and Shakuni, who spent a lifetime on a revenge nobody else remembered.
Each is a different answer to the same question: what do you do when your duty, your loyalty and your conscience point in three directions?
