Korean shamanism (Muism)

Overview

Musok, often called Korean shamanism, is the oldest religious practice on the Korean peninsula: communication with gods, ancestors and nature spirits through a shaman, or mudang, who falls into trance so that a spirit can speak through her. It has no founder, scripture or congregation, and no single rite is compulsory, yet it has outlasted every religion later imported into Korea. Buddhism, Confucianism and Christianity each displaced it from official favour and, at times, actively suppressed it as superstition, but families and villages have continued to call on mudang for healing, for comfort after death and for good fortune. Since the 1980s, scholars and the state have increasingly treated musok as living folk heritage rather than backwardness, protecting individual rituals even though shamanism itself is not counted as one of Korea's religions.^{[1–2, 5, 7–8]}

History

Shamans and sacred kingship c. 4000 BCE – 1st century BCE

Korea's earliest known religious practice descends from Siberian shamanism, carried by peoples whose Neolithic pottery resembles finds across Siberia, Manchuria and Mongolia. In this early period shamans were male and closely tied to political power: as tribal leagues grew into early states, shamanism became integral to the idea of sacred kingship, and heaven-sent ancestry legitimised rulers. Korea's founding legend, the myth of Tan'gun, is itself a shamanic narrative: a heavenly king and three thousand spirits descend to Mount T'aebaek by a sandalwood tree, and Tan'gun, born of a bear transformed into a woman, founds the state of ancient Chosŏn before becoming a mountain god.^{[1, 9–10]}

Buddhism rises, musok falls from favour 4th century – 1392

As Buddhism became the state religion of the unified Silla and Koryŏ kingdoms, it took over the shaman's role as protector of the throne, and the standing of mudang grew ambiguous: court records describe officials consulting them even as royal proclamations condemned "licentious" rites and taxed those who performed them. The Tan'gun myth survived chiefly through musok practice and was set down in writing only in 1285, when the Buddhist monk Iryŏn recorded it in the Samguk yusa, one of the earliest surviving compilations of Korean legend.^[11–12]

Branded "obscene" under Confucian rule 1392–1910

The Chosŏn dynasty made Confucianism state orthodoxy and pushed both Buddhism and musok to the margins, labelling shamanic rites ŭmsa, "obscene", for their uninhibited dancing, singing and trance. Even so, mudang kept a place even in the royal palace, where some were retained as "national shamans", and shamanism remained, in the words of one scholar, "the most basic substratum of folk religion". Practitioners became mostly women of reduced social standing, a position they have largely kept since.^[13–14]

Superstition, suppression and heritage 1910–present

Japanese colonial rule, Christian missionaries and later state-led modernisation all denounced musok as backward superstition, yet it survived, limited mainly to occasions such as illness, death and misfortune. Foreign rule and national division also drove new scholarly and popular interest in musok as a marker of shared Korean folk identity, and since the 1980s individual rituals, including the Jeju Chilmeoridang Yeongdeunggut, have been recognised as cultural heritage even as noisy private rites have been restricted in cities such as Seoul.^[7–8]

Beliefs

Spirit possession · 신내림 sin-naerim

a spirit's descent into the shaman

Classic definitions of shamanism centre on the soul's flight to other worlds, but Korean shamans instead become possessed: a god or spirit is said to "descend" into the mudang and speak and act through her, rather than her journeying to meet it. The identity of the possessing spirit is determined through divination at the start of a rite.^[3]

Spirits and gods · 신령 sillyeong

spirits, numinous powers

Musok holds that mountains, rivers and other natural features, as well as ancestors and heavenly beings, are animated by spirits that can help or harm the living. Troublesome ancestors, those who died badly or were neglected, are thought to cause illness and misfortune until properly placated through ritual.^[3]

Hereditary and possessed shamans · 세습무 · 강신무

sesŭmmu; kangsinmu

Korea has two distinct kinds of shaman. The charismatic kangsinmu, found mainly in the north and centre, is chosen by a spirit and channels it in trance. The hereditary sesŭmmu of the southern provinces, including the simbang of Jeju Island, inherits ritual office within the family and entertains the gods with song and dance but does not experience possession.^[15]

Women's rite

The great majority of kangsinmu are women, and the calling has long given women of modest social standing a rare position of ritual authority, in contrast to the male-centred rites of Confucianism, Buddhism and Christianity.^[16–17]

Practice

The gut ritual · 굿

A gut is a trance rite of singing, dancing and offerings performed before an altar to call a spirit into the mudang, who is then said to speak and act as the spirit and to pass its message to the client. A full gut, reserved for serious illness or prolonged misfortune, can last up to three days and is preceded by divination to identify the cause of trouble.^{[5, 18]}

Kinds of gut

The basic categories of gut, still performed today, are mortuary rites that send ancestors safely onward, healing rites for the sick, and good-luck rites that invoke heavenly and natural spirits as well as village guardian gods.^[19]

Becoming a shaman · 신병 sinbyeong

A kangsinmu's calling usually begins with "spirit sickness", physical and mental illness blamed on an unwanted possession, which can be cured only by an initiatory gut in which the sufferer identifies the possessing spirit. She then apprentices to a senior mudang, in effect a spiritual mother, until fully initiated.^[20]

Village and seasonal rites

Villages, as well as families, sponsor gut for collective ends, above all for a good catch or harvest. On Jeju Island, village shamans still perform the Chilmeoridang Yeongdeunggut each spring, calling on the wind goddess, the Dragon King and mountain gods, a ritual sustained mainly by the women divers and boat owners whose livelihoods depend on the sea.^[21]

Holy days

Chilmeoridang Yeongdeunggut · 칠머리당영등굿

Second lunar month (February–March)

A Jeju Island ritual, inscribed by UNESCO in 2009, in which village shamans welcome and then send off the wind goddess Grandmother Yeondeung with prayers for calm seas and a good catch, including a farewell rite with fortune-telling and the launching of a straw boat.^{[7, 21]}

Tan'gun's mountain sacrifice · 단군제

October

By legend Tan'gun became mountain god after departing human rule, and October sacrifices are offered to him on mountaintops, most significantly at Mount Mani on Kanghwa Island, where an altar said to have been built by Tan'gun himself still stands and is periodically refurbished.^[22]

People

Scripture

Samguk yusa · 삼국유사

1285

"Memorabilia of the Three Kingdoms", compiled by the Buddhist monk Iryŏn, is the earliest surviving written record of the Tan'gun myth and a major source for Korea's founding legends, composed under Mongol rule as an assertion of native identity.^[11]

Places

Chilmeoridang shrine, Jeju Island

KOR

The shrine in the village of Gun-rip where the Yeongdeunggut is centred; UNESCO lists the rite as representative of similar seasonal shaman ceremonies held across Jeju Island.^{[7, 21]}

T'aebaek Mountains

KOR

This mountain range, which runs the length of the Korean peninsula's eastern side, includes the Mount T'aebaek of the Tan'gun myth, where heaven-sent spirits are said to have descended to found Korea's first state.^[10]

How we know

Why shamans are hard to count

Musok has never been a religion one joins or leaves, so it was not classified as an affiliation Koreans could choose in censuses or surveys, and no reliable count of mudang or clients exists. Its persistence shows instead in surveys where only about half the population identifies with Buddhism, Christianity or another organised religion at all, leaving musok's extent to be inferred from continued demand for gut rather than measured directly.^{[6, 23]}
