'Not to injure' also reffered as nonviolence is one of the cardinal virtues in Buddhism. What is it called?

Ahimsa means 'not to injure' and 'compassion' and refers to a key virtue in Indian religions. 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—in ancient Indian religions.
