direction. There emerged in Java a loosely structured society of religious leadership, revolving around kyais, possessing various degrees of proficiency in pre-Islamic and Islamic lore, belief and practice. The kyais are the principal intermediaries between the villages masses and the realm of the supernatural. However, this very looseneess of kyai leadership structure has promoted schism. There were often sharp divisions between orthodox kyais, who merely instructed in Islamic law, with those who taught mysticism and those who sought reformed Islam with modern scientific concepts. As a result, there is a division between santri, who believe that they are more orthodox in their Islamic belief and practice, with abangan, who have mixed pre-Islamic animistic and Hindu-Indian concepts with a superficial acceptance of Islamic belief.
A wider effect of this division is the number of sects. In the middle of 1956, the Department of Religious Affairs in Yogyakarta reported 63 religious sects in Java other than the official Indonesian religions. Of these, 35 were in Central Java, 22 in West Java and 6 in East Java. These include Kejawen, Sumarah, Subud, etc. Their total membership is difficult to estimate as many of their adherents identify themselves with one of the official religions
