When two or more religious belief systems are combined into a new system, this is known as religious syncretism. It may also be defined as the incorporation of beliefs from unconnected traditions into a religious tradition. Polytheism and numerous religious affiliations, on the other hand, are seen as diametrically opposed to one another. These situations can arise for a variety of reasons, with the latter scenario occurring quite frequently in areas where multiple religious traditions coexist in close proximity to one another and are actively practised in the culture. It can also occur when a culture is conquered, with the conquerors bringing their religious beliefs with them but not succeeding in completely eradicating the old beliefs, and especially the old practises.Faiths' beliefs or histories may have syncretic components, however members of these so-labeled systems sometimes object to the label's use, particularly those who belong to "revealed" religious systems, such as Abrahamic religions, or any system that takes an exclusivist stance. Syncretism is viewed as a betrayal of the pure truth by some supporters of such beliefs. According to this logic, introducing a belief that is incompatible with the original religion corrupts it and renders it untrue altogether. Indeed, detractors of a certain syncretistic trend may occasionally use the term "syncretism" as a derogatory pejorative, meaning that individuals who attempt to adopt a new idea, belief, or practise into a religious system are really distorting the original faith by doing so. A fatal compromise of the integrity of the prevailing religion is, according to Keith Ferdinando, as a result of this development. Religions that are not exclusivist, on the other hand, are likely to feel free to absorb other traditions into their own systems of thought.Many traditional beliefs in East Asian civilizations have become entwined with Buddhism due to the assumption that Buddhism is compatible with local religions. The Three Teachings, or Triple Religion, which harmonizes Mahayana Buddhism with Confucian philosophy and elements of Taoism, and Shinbutsu-shg, which is a syncretism of Shinto and Buddhism, are two examples of notable concretizations of Buddhism with local beliefs. The Three Teachings, or Triple Religion, harmonizes Mahayana Buddhism with Confucian philosophy and elements of Taoism, and Shinbutsu-shg, which East Asian religious beliefs, practises, and identities (who, by any measure, constitute the majority of the world's Buddhists) frequently incorporate elements of other religious traditions, such as Confucianism, Chinese folk religion, Taoism, Shinto, and Korean shamanism, into their Buddhist beliefs, practises, and identities. Nichiren Shush priest Jimon Ogasawara advocated a fusion of Nichiren Buddhism and Shinto just before and during World War II, but his proposal was rejected. Over the millennia, Hinduism, Buddhism, Jainism, and Zoroastrianism in ancient India have undergone several transformations, integrating aspects from a wide range of varied religious traditions.
