Jainism is one of the oldest religions in India dating back to at least the 1st century BCE. It teaches that the path to enlightenment is through nonviolence and minimizing harm to all living things as much as possible. Jains practice strict vegetarianism and even avoid foods like root vegetables that would kill the plant. Monks and nuns try to avoid harming any living thing, even insects. Jainism's principles of nonviolence have influenced other religions in India such as Hinduism.
