Some other examples where the phrase "Ahimsa Paramo Dharma" are discussed include Adi Parva, Vana Parva and Anushasana Parva. The Bhagavad Gita, among other things, discusses the doubts and questions about appropriate response when one faces systematic violence or war. These verses develop the concepts of lawful violence in self-defence and the theories of just war. However, there is no consensus on this interpretation. Gandhi, for example, considers this debate about non-violence and lawful violence as a mere metaphor for the internal war within each human being, when he or she faces moral questions.
