Greetings Everyone! Please excuse me for interjecting into your discussion.
No doubt there are many possible interpretations of ahimsa in Krishna Consciousness. When I wrote about ahimsa in "Pretender", I was primarily referring to consciously avoiding inconsiderate meanness or cruelty towards all other embodied beings(people, plants, critters) as much as possible, but especially in the name of religion (which actually proves whether or not one is really religious being that ahimsa is considered a sub-religious principle). For me it's a mood with which I sincerely hope to suffuse my existence with and not necessarily a specific separate teaching or practice per se. As embodied beings it is our basic unconscious exploitative nature to nurture our physical body at the mortal expense of many other living entities from the sub-atomic, microbial level on up to the vegetables we eat, etc.(I'm not vegan but consider myself simply vegetarian white trash) Personally, the way that I have tried to harmonize this sacrifice of other living entities so that my body might continue living is to hopefully make my life into something truly mutually beneficial to others and thereby worthwhile to the world by real internal development while striving to be unconditionally friendly and helpful in my many dealings with other embodied beings.
Because I live in the woods off of a river in a subtropic climate, unfortunately there may be times when I am unable to avoid harming other living creatures like mosquitos or horseflies. Or the carpenter ants that would like to eat my woodframe house. In such cases I might at least try to feel apologetic for causing suffering to another in my unavoidable violent display. "Sorry little brother. Better life next time." And also be fully willing to bear the karmic brunt of my harmful act towards another living being. As I have made them suffer, so I must also suffer. Sometimes I may have to kill, but at least I shouldn't feel good about it.
Sometimes I wish we could just start with upadharma or common sense religion and grow from there. Possibly, serious spiritual issues might be less vehemently addressed as the universal human nature problems which they really are from a more neutral ground of elemental spirituality, with humility and respect for others as a fundamental salient point of real collective spiritual progress. For the real benefit of all suffering souls of this world.
