Krishna Consciousness is also a sort of fight; but not with rifles. Our weapon is karatalas. In this age there is no need of fighting with rifles because the population is so poor that they are already killed by so many disturbances. They are short lived, poor in knowledge, slack in advancement of spiritual life, unfortunate, and embarrassed by so many miserable conditions of life; like war, famine, pestilence, poverty and so on. So to kill these persons by rifle is like bringing a cannon for killing a mosquito. So Lord Caitanya introduced this fighting principle of Sankirtana Movement to reclaim all the fallen souls, who consist of so-called philosophers, half-educated scientists, misguided educationists and a miscreant society. If you can consolidate a party of soldiers as described by you, chanting Hare Krishna Mantra and claiming everyone of them to Krishna Consciousness, that will be a glorious task, and you have all of my good wishes for you for this purpose.
