Angkor Wat is the ultimate expression of Khmer genius – an awe-inspiring temple that is stunning for both its grand scale and its incredible detail. The modern Khmer people strongly identify their ethnic identity with their religious beliefs and practices, which combine the tenets of Theravada Buddhism with elements of indigenous ancestor-spirit worship, animism and shamanism. Most Cambodians, whether or not they profess to be Buddhists (or Muslims), believe in a rich supernatural world. Several types of supernatural entities are believed to exist; they make themselves known by means of inexplicable sounds or happenings. Among these phenomena are khmaoc (ghosts), pret and besach (particularly nasty demons, the spirits of people who have died violent, untimely, or unnatural deaths), arak (evil spirits, usually female), neak ta(tutelary spirits residing in inanimate objects), mneang phteah (guardians of the house), meba (ancestral spirits), and mrenh kongveal (elf-like guardians of animals). All spirits must be shown proper respect, and, with the exception of the mneang phteah and mrenh kongveal, they can cause trouble ranging from mischief to serious life-threatening illnesses.
