Ahimsa (nonviolence) is a basic moral principle. It has been advocated not only by the Hindus, the Buddhas and the Jainas, but also by the Mohammedans. Accepting moderately violence in the cases of just war,eating,preparing medicine and awarding punishment as advocated in the ethics of the Hindus and the Mohammedans and adding the Buddhist principle of nonviolence,we can build up a tradition of nonviolence for the betterment of future human civilization.
