Ahimsa (Sanskrit: अहिंसा; IAST: ahimsā, Pāli: avihiṃsā) 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. Thank you Amit Kanodia for sharing this word with me !
