The main purposes of this thesis were to study the history of the Baisrisukhwan, believes and ritual about the Wanonniwat people’s Baisrisukhwan ritual, and the Principles in believes and the Baisrisukhwan ritual of  Wanonniwat  people, Wanonniwat sub-district, Wanonniwat district, Sakonnakhon province. 

                         It was found that it was not clear about the history of the Baisrisukhwan ritual. All experienced people said that this ritual was derived from the ancient time. In fact, Baisri was a central medium of representing a good tradition, respect, and faith of people in the past time who were conscious of their parents’ virtue and teacher’s goodness through giving faith in a person. They came together to grow value of the local people’s knowledge that was recognized as a great identity of the community derived from the past to the present.

                         About believes and ritual about Baisrisukhwan of the Wanonniwat people, it was found that it was mixed with the original belief, Brahman’s belief and the Buddhist belief. The Wanonniwat  people derived it with a symbol of the Baisrisukhwan ritual that could possibly be divided into three kinds. The first kind was to welcome back the people’s morale the Sangha’s morale, the aged people’s morale, the married people’s morale, and the ill people’s morale. The Principles that could be applied to the daily life were also found in this ritual. The second kind was to welcome back an animal’s morale. This ritual was found only in welcoming back the buffalo’s morale. There was no welcoming back the other animal’s morale because the Wanonniwat people believed that a buffalo was meritorious. There was no the Buddha’s teachings found in this ritual. The third kind was to welcome back morale of things-rice, a new house, an occupied house, and the shrine of the Takhienthong spirit. There was no the Buddha’s teachings found in this ceremony. By means of the present factors of occasion, time, place, belief and action, a way of performing the Baisrisukhwan ritual was generally varied for all kinds of this ceremony.

                About the Principles in the Baisrisukhwan ritual of Wanonniwat people, Wanonniwat sub-district, Wanonniwat district, Sakonnakhon province, it was found that they appeared in three stages of Baisri, five stages of Baisri, seven stages of Baisri, and nine stages of Baisri. The Wanonniwat people compared all stages to the Principles-three kinds of good conduct, five precepts, seven kinds of sublime treasure, and nine meritorious characteristics of the Buddha. As a result, this ritual was a way to derive a tradition, a convention, and the local people’s knowledge that were really studied in the next generations.
