From mettacenter.org’s blog:
Gandhi was once given a seemingly impossible scenario: what would he do if a plane were flying over his ashram to bomb him? He rose to the challenge with an equally challenging answer: he would pray for the pilot. Some may take Gandhi’s response as preposterous. I argue, however, that his call to prayer was consistent with his vision of nonviolent strategy, for at least three reasons.
Reason 1: It meets the escalation of physical force with soul force.
Reason 2: It overcomes the tendency toward fear and flight.
Reason 3: It is constructive as well as a form of resistance.
