Taegeuk in the context of "Flag of South Korea"

Korean shamanism, also known as musok (Korean: 무속; Hanja: 巫俗), is a religion from Korea. Scholars of religion classify it as a folk religion and sometimes regard it as one facet of a broader Korean vernacular religion distinct from Buddhism, Daoism, and Confucianism. There is no central authority in control of musok, with much diversity of belief and practice evident among practitioners.

A polytheistic religion, musok revolves around deities and ancestral spirits. Central to the tradition are ritual specialists, the majority of them female, called mudang (무당; 巫堂). In English they have sometimes been called "shamans", although the accuracy of this term is debated among anthropologists. The mudang serve as mediators between paying clients and the supernatural world, employing divination to determine the cause of their clients' misfortune. They also perform gut rituals, during which they offer food and drink to the gods and spirits or entertain them with storytelling, song, and dance. Gut may take place in a private home or in a guttang shrine, often located on a mountain. The mudang divide into regional sub-types, the largest being the mansin or kangsin-mu, historically dominant in Korea's northern regions, whose rituals involve them being personally possessed by deities or ancestral spirits. Another type is the sesŭp-mu of eastern and southern regions, whose rituals entail spirit mediumship but not possession.
