Sizeable populations in Java, Kalimantan, and Papua practice animism and other types of traditional belief systems termed "Aliran Kepercayaan." Many of those who practice Kepercayaan describe it as more of a meditation-based spiritual path than a religion. Some animists combine their beliefs with one of the government-recognized religions.
As a body of belief, kebatinan is officially recognized in the 1945 Indonesian constitution; however, to avoid recognizing it as a formal religion, it is administered by the Department of Education and Culture rather than by the Department of Religious Affairs. The Indonesian Government recognizes the right to follow Aliran Kepercayaan, as long as its practitioners do not upset the public order or offend the sensitivities of the followers of the major religions.
