Buddhism has long been recognized as a religion of peace and non-violence. In today’s world, various conflicts take place between nations, religions, and ethnic groups. Buddha saw that people can live together freely as individuals, equal in principle, and therefore responsible for each other. Buddha explains that every member of the human family, man and woman alike, has an equal right to liberty. He recognized that each of us is just a human being like everyone else. The Buddha has given (...) this example in his own monasteries. The monks who belonged to different castes were given the opportunity to spend time together in the same monastery, which included holding meetings altogether, irrespective of ethnicity, caste, or religion, walking together in the Pindapātha, and holding Dhamma discussions together in the one Dhamma hall. The objective of this study is to identify Buddha’s teaching on social and ethnic harmony throughout the Buddhist scriptures (Pāli Canon) and consider its application in conflict resolution. Special attention will be paid to the doctrine preached by the Buddha which can be applied to build mutual understanding, relationships, and peace. The study method in this study is historical texts (Sutta Pitaka) content analysis and is carried out using the library survey methodology. (shrink)
