Ahimsa (; IAST: , Pāli: ) is a term meaning 'not to injure' and 'compassion'. The word is derived from the Sanskrit root hiṃs – to strike; hiṃsā is injury or harm, a-hiṃsā is the opposite of this, i.e. cause no injury, do no harm. Ahimsa is also referred to as nonviolence, and it applies to all living beings - including all animals - according to many Indian religions.
