In the "Bhagavad Gita," which was Gandhi's favorite book, God appears to the warrior, Arjuna, on a battlefield just before combat.

If you march in a political demonstration, passionately shouting your beliefs against those who shout against you, shutting down traffic and commerce to stop the war, is that action? If you stand still for hours in silence, with a vigil candle in hand, before a court house or a military recruiting station, is that action?

They led him away to be crucified.
Why didn't he do something?
