Originating in the Indian subcontinent, Jainism - or, more properly, the Jain Dharma - is one of the oldest religions of its homeland and indeed of the world. Jains believe that their religion is without a beginning. The twenty-four Tirthankars guided its evolution and elaboration by first achieving, and then teaching the path to salvation. Jain religion is unique in that, during its existence, it has never compromised on concept of nonviolence either in principle or practice. It upholds non-violence as the supreme religion (Ahimsa Paramo Dharmah) and has insisted upon its observance in thought, word, and deed at the individual as well as social levels.
