The study focused specifically on the historical, religious, educational, social, and institutional roles that Buddhist monasteries and monastic leaders have had throughout Cambodia's history. According to the findings, the monastic practice of Buddhism in Cambodia encompasses a wide range of activities that go much beyond its intended religious purpose. Monasteries are community-based institutions that offer chances for religious instruction, moral growth, cultural preservation, charity aid, youth involvement, peacebuilding, and community mobilization. Pagodas can be found in the smallest communities and the most rural of areas; they are the glue that holds Cambodian Buddhist society together. They are both a sanctuary for the poor and a place where traditions are upheld and knowledge is transferred. Gyallay-Pap notes that even after Cambodian society went through years of genocide and repression, “it was wat structures that spontaneously re-emerged to begin the reconstruction process, not state structures or even party structures.” Each element of the Wat has an important role to play and provides opportunities for partnership with external development actors. Traditionally, Wat has been the center of the community, providing a space for community gatherings and worship while also acting as a shelter for the poor and a center of learning. It is typically made up of three basic buildings: the Vihear, the Sālā, and the Kuṭi. The Vihāra is the place of worship for Buddhists, where ceremonies are held. Monasteries also give opportunities for youth participation. Their contribution is especially essential due to the fact that monasteries are deeply rooted in the areas in which they are located and their relationships with laypeople have been developed for several years. This accessibility enables Buddhist organizations to react to social needs at the community level and to give support to populations who may encounter problems accessing formal institutions. The study sheds more information on the function that Buddhist institutions play in the process of constructing peace and fostering social cohesiveness.
