Cimande always assumes there is a minimum of three enemies, but advanced students may spar with up to twelve opponents. As a defensive art, Cimande has no lethal techniques. The town of Cianjur - seen as the heartland of Sunda culture - is associated with a few systems, the most prominent of them being "Cikalong" or bat style. Borrowing its technical base from Cimande, Cikalong was founded by Raden Jayaperbata after meditating in a cave in the Cikalong Kulon village. While Cimande may attack with either the fists or open hands, Cikalong prefers the latter. Prominent Sunda weapons include the "toya" (staff), "cabang" (forked truncheon), long-bladed "parang" (machete) and heavy "golok" (cleaver). The advanced weapon is the "piau" or throwing knife. The Minangkabau formed the dominant sovereignty in West Sumatra and make up the majority of Sumatran pencak silat systems. These styles may be referred to as "silat Minangkabau", "silat Padang" (lit. field silat), or "silek", the local pronunciation of silat. Very few systems in Indonesia have not been influenced by silek, and its techniques form the core of pencak silat throughout Sumatra. It developed as an extension of the original silat Melayu from Riau. Folklore traces this to five masters, namely Ninik Datuak Suri Dirajo from Padang Panjang, Kambiang Utan ("forest goat") from Cambodia, Harimau Campo ("tiger of Champa") from Vietnam, Kuciang Siam ("Siamese cat") from Thailand and Anjiang Mualim ("teacher dog") from Gujarat. Stealth and ambush were the preferred Minang war tactics, and they were said to be among the best assassins in the world when dispatched singly. Silek Minangkabau is characterised by its low stances and reliance on kicks and leg tactics. The low stance is said to have developed to offset the chance of falling on slippery ground, common in the rice fields of West Sumatra. The local practice of paddling rafts with the legs strengthened fighters' lower body muscles. Hand and arm movements are fast, honed through an exercise in which the exponent stands across from a partner tossing sharpened sticks or knives.
