Balians (shamans) are traditional Bali healers who work with divine energy to treat physical and mental illnesses, remove spells and channel energy from ancestors. Some Balian have learned their art from studying the ancient scriptures called lontar and apprenticing with a master. Others have received wahyu or divine inspiration and heal from the heart. Both have an esteemed place in Balinese society. Often the problem lies with the ancestors, who can cause mischief or indeed real harm if not treated regularly to their favorite treats and offerings. Balians may go into a trance state to discover the root cause of the problem and either give the patient natural plant medicine, a massage or a list of offerings to be made.
