On the Indonesian island of Bali, the arts permeate almost every aspect of daily life. Gamelan music, wayang (shadow puppet) theater, dance, and elaborately constructed offerings of foods and flowers all represent attempts to please the gods and placate demons. In Balinese cosmology, demons are thought to dwell in the watery underworld, gods in the upper world, and human beings in the middle realm between the two. Much of human effort is directed toward maintaining the proper balance between these worlds, and between the forces of growth and decay. The pinnacle of such efforts is the ritual Eka Dasa Rudra, held once every hundred years. The entire population of the island is mobilized for this event, preparing offerings and streaming from thousands of village temples in processions to the sea. Eleven demons, of which Rudra is the most powerful, must be transformed into beneficient spirits. No one who participated in the ritual filmed in 1979 had ever witnessed its performance, which last occurred a century ago, and so the ritual was based on writings in ancient lontar-palm manuscripts. There is also a political dimention to Eka Dasa Rudra. In 1963, upon the urging of then President Sukarno, Balinese priests prepared to hold the ritual before the calendrically proper year. Preparations were met with the first eruption in recorded history of Bali's great volcano, Gunung Agung. This terrible disaster was seen as a confirmation of the gods' and demons' powers and the necessity of honoring the traditional calendar. In the spring of 1979, when Eka Dasa Rudra was finally held, President Suharto arrived, but not by his helicopter, which, it was feared, might have impeded the demons' descent.
