Pencak Silat the technically superior. IPSI has avoided the tendency of modern martial arts that gravitate towards sport. The resistance to sport has lessened over time, however, and sparring in particular has become less combative. While nominally an Indonesian organisation, many of the rules and regulations outlined by IPSI have become the de facto standard for silat competitions worldwide. Indo-Dutch Eurasians who first began practicing pencak silat in the 20th century spread the art to the west in the late 20th century. Today pencak silat is one of the extra-curricular activities taught in Indonesian schools. It is included as a combat sport
Pencak Silat less direct than other styles, characteristically favouring deception over aggression. Hand movements are used to distract, and openings are deliberately exposed to bluff the opponent into attacking. This approach requires that exponents train their flexibility and stamina. As with Balinese warriors of the past, modern pencak practitioners in Bali often wear headbands as part of their uniform. There are about four main systems considered purely Balinese. The most prominent of these is Bakti Negara, which is firmly rooted in the old local Hindu philosophy of Tri Hita Karana. Another system which has gained prominence is Seruling Dewata meaning "God's flute".
