A shared term with different scope
Ahimsa is central to Jain and Yoga traditions and closely parallels the first Buddhist precept. The traditions differ over absolute application, intention, occupation, diet, indirect participation and the demands placed on monastics and householders.
Direct and indirect harm
A serious comparison must examine not only deliberate violence but also economic support, negligence, environmental damage and harm to animals.
Difficult cases
Medical treatment, agriculture, self-defence and protection of others show why a general commitment to nonviolence still requires judgment about competing harms.
