Indonesian martial arts includes a variety of fighting systems native to or developed in the archipelago of Indonesia, both the age-old traditional arts, and the more recently developed hybrid combatives. In the Indonesian language the term bela-diri (lit. self-defense) is used to mean martial art, and in essence the Indonesian fighting arts are meant as one's defence against perceived threat and assault. Other than physical training, they often include spiritual aspects to cultivate inner strength, inner peace and higher psychological ends.
