There are many kinds of spirit in Cambodia. One of the most important is the boramey, a powerful and benevolent supernatural being who works to help humans in this world through a human representative. The representative is possessed by the boramey and becomes the boramey for the duration of the possession. An academic who has studied spirit-possession says there are over ten thousand boramey in Cambodia, all of them named and identifiable.
Fortune telling, prophecies and finding ways to influence fate form the backbone of Cambodian culture. Such things are intricately woven into ancestor worship, the spirit world and more orthodox ideas of Theravada Buddhist teachings. The above prophecy is known to pretty much every Khmer old enough to have heard it (go on, ask), and gets updated by each generation to ‘prove’ its authenticity.
