The form of Buddhism in Sri Lanka is known as Theravada (school of elders). The Pali chronicles (e.g., the Mahavansa) claim that the Sinhalese as an ethnic group are destined to preserve and protect Buddhism. In 1988 almost 93% of the Sinhala speaking population in Sri Lanka were Buddhist. Observations of current religious beliefs and practices demonstrate that the Sinhalese, as a religious community, have a complex worldview as Buddhists. Due to the proximity and on some occasions similarity of certain doctrines, there are many areas where Buddhists and Hindus share religious views and practices. Sinhalese Buddhists have adopted religious elements from Hindu traditions in their religious practices. Some of these practices may relate to ancient indigenous beliefs and traditions on spirits, worship of Hindu deities. Some of these demonic figures are used in healing rituals and may be native to the island.
