The Bun Yor That merit-making ceremony of this ethnic group is divided into two stages; preparation and execution. Each stage has four components, namely personnel, temporal, spatial and material. It is traditionally believed that monks conducting the ceremony are moral and ethical, adhere to Buddhist principles, are good role models and spiritual refuges for laypeople, and have the duty to spread Buddhist teachings. They are presumed to be performers of the ceremony. The ceremony takes place for two days after the Song Kran Festival on April 19-20. Materials prepared in advance include a Buddha image, ceremonial items and items offered to monks. Materials brought to the ceremony include flowers, candles and joss sticks, soil, rocks, sand, food, sweets, scented water, bee castles, and a money tree. There are three kinds of beliefs related to the ceremony: folk Buddhism, folk Brahminism and animism. These beliefs are related in that Buddhist and Brahministic ceremonies are aimed at dedicating merits to the deceased. Changes in the culture stem from cultural promotion, changes in human needs, socio-environmental changes, cultural borrowing, and changes brought about by new knowledge and technology. It can be viewed that these changes are for the better, with the use of creativity to express the distinct ethnic identity of the group.
