In this documentary, Prof. Dr. Janet Hoskins, Professor of Anthropology and Religion at the University of Southern California, provides an introduction to the history of Caodaism and its link to the practice of spirit-writing. Caodaism is a Vietnamese new religion that emerged in Southern Vietnam in the 1920s. Its early religious scriptures were revealed through a slightly adapted form of Chinese spirit-writing and ascribed to different deities of the Sino-Vietnamese pantheon and other religions. Caodaism turned into a large religious organization but was repressed by the Communist government after 1975 due to its linkages to the former South Vietnamese government. However, it survived in the diaspora and underwent a revival in Vietnam in recent years.
