A person on the spiritual path has no right to be in military service. But if he refuses he commits a worse crime, for in so doing he is asking someone else to do it for him. That is the point that is overlooked. A conscientious objector, by his very attitude, is harming two people - himself and the person who has to replace him. The Bhagavad Gita has a good passage on that: "He who shall say, 'Lo! I have slain a man!' He who shall think, 'Lo, I am slain,' those both know naught. Life cannot slay. Life is not slain."
