According to Srimad-Bhagavatam, one living entity subsists on the life of other living entities, either vegetarian or non-vegetarian. But we are neither of them. We are not vegetarian nor non-vegetarian. We are transcendental. We are concerned with Krishna Prasadam. Try to popularize Krishna Prasadam as you have already done. People will naturally become vegetarian without any ghastly propaganda.
Letter to Rayarama, 19 November, 1968
