The Balinese practice a unique form of the Hindu religion that they call Agama Hindu Dharma, which is something of an amalgam of "traditional" Hinduism, Buddhism, animism, ancestor worship, Zen and perhaps even a little Shinto. We in the West tend to think of Hinduism as a form of polytheism, but this is erroneous. 

Balinese Hindus believe in one supreme being known as 'Ida Sanghyang Widi Wasa', 'Sang Hyang Cintya', or 'Sang Hyang Tunggal'. This ultimate godhead is, in truth, beyond human ability to comprehend, and is manifest through the three primary Balinese gods: Bhrama, Wisnu and Siwa (note the difference from the traditional Hindu names of "Vishnu" and "Shiva"). These three aspects of the divine are referred to, respectively, as "the creator," "the preserver" and "the destroyer."

Our friend and guide Hadde explained it to us this way: " In the West you believe in "God" - G.O.D. For us it is the same. We believe in Brahma, Siwa and Wisnu - Generator, Operator and Destroyer. G.O.D. there is no difference!"

This just goes to show you that, despite the seemingly exotic quality of Balinese religion - there is really a single truth that unites us all.
