Ahimsa doesn’t mean you don’t have to do anything, it means you do, in a non-aggressive way.
You participate, you take a role. And in fact, the ultimate fulfillment of ahimsa is not just you don’t do harm but you intervene when you see harm being done, in order to that should be stopped. So today, in a world we’re very much dependent on one another, actual non-violence is a very active socially engaged proposition. So that’s kind of the message of the Gita as well. ~ Joshua M. Greene
