Kirat Mundhum Belief System Explained: Sakela, Yele Sambat & Scripture

Kirat Mundhum — also written Kiratism, Kirati Mundhum or simply the Kirat religion — is the traditional belief system of the Kirati (Kirant) peoples of the eastern Nepal hills and the neighbouring Darjeeling, Kalimpong and Sikkim regions of India. Its main communities are the Rai (Khambu), the Limbu (Yakthung), the Yakkha, the Sunuwar and, in the eastern Tarai, the Dhimal and Hayu. Rather than a scriptural, temple-based religion, it is a blend of nature worship, ancestor veneration and shamanism, and it is one of Nepal's officially counted religions.

In Nepal's 2021 census (2078 BS), 924,204 people — roughly 3.17% of the population — identified their religion as Kirat, making it the country's fifth-largest religion after Hinduism, Buddhism, Islam and Christianity. The figure rose slightly as a share from 2011, reflecting a broader identity-driven revival among Kirati youth who increasingly register Kirat rather than Hindu. The census counts religion separately from ethnicity, so not every Rai or Limbu returns 'Kirat', and some also identify as Hindu, Buddhist or Christian.

Because it has no single founder, no central church and no printed canon, Kirat Mundhum is best understood as a family of closely related local traditions united by a shared oral heritage (the Mundhum), shared deities of earth and sky, and a shared seasonal ritual calendar. This page goes beyond the census statistic to explain the Mundhum scripture, the deities, the priestly roles, the Yele Sambat calendar and the Ubhauli–Udhauli / Sakela cycle that together define the faith.

The Mundhum is the sacred scripture and folk literature of the Kirat religion — but for most of its history it has existed as memorised, chanted oral text rather than a printed volume. The word means roughly 'the power of great strength' in the Limbu language, and it appears under cognate names across the Kirati tribes: muddum among the Mewahang, mintum among the Yakkha, mukdum among the Sunuwar, ridum among the Kulung and mudum among the Chamling Rai. It is transmitted in ritual language, distinct from everyday speech, and passed down priest to disciple over years of apprenticeship.

The Mundhum functions simultaneously as cosmology, genealogy, law, medicine and liturgy. It narrates the creation of earth, water, air, fire and life; the origin of humankind and of the Kirati clans; and the proper conduct of every rite of passage — birth, naming, marriage, healing and death. During ceremonies a priest recites the relevant portion of the Mundhum to summon deities and ancestors, diagnose misfortune and restore balance between the human world and nature. Because it is chanted in a specialised register, only trained ritual specialists can perform it fully.

Since the 20th century, Kirat scholars and cultural associations have worked to write down and publish the Mundhum in Devanagari, in the Limbu Sirijunga script and in Roman transcription, both to preserve it and to standardise teaching. This documentation effort — alongside academic ethnography of the Rai, Limbu and Yakkha — has turned a once-endangered oral tradition into a growing body of printed literature, though practitioners stress that the living, recited Mundhum remains the authoritative form.

Kirat Mundhum centres on a paired creator principle of earth-mother and sky-father, alongside the veneration of clan ancestors and nature spirits dwelling in mountains, rivers, forests, stones and the household hearth. There are no idols or grand temples in the classical tradition; worship takes place at home altars, at natural sacred spots and at open ritual grounds, with offerings of millet, rice, ginger, eggs, flowers and locally brewed drinks.

Among the Limbu (Yakthung), the supreme creator is Tagera Ningwaphuma, an all-knowing formless power personified in her earthly, maternal form as Yuma Sammang (the grandmother goddess) and in the male aspect as Theba Sammang. Yuma worship is central to Limbu spiritual life. Among the Rai (Khambu), the primal couple is Sumnima, the earth-mother goddess, and Paruhang, the sky-god — figures whose story of separation and reunion underlies much Rai ritual and moral teaching.

Ancestor worship binds these cosmic deities to daily life: the household hearth and the ancestral spirits (such as the Limbu Samjik) are honoured at first-harvest and life-cycle rituals, so that prosperity, health and fertility are understood as gifts to be reciprocated with gratitude and offerings. This continuity between nature, ancestors and the living is the ethical core of the Mundhum worldview.

Because the Mundhum is oral, the priest-shaman who memorises and recites it is the living heart of the religion. Different Kirati communities use different titles for these ritual specialists, but all serve overlapping functions: keeper of the Mundhum, officiant of rites of passage, healer of sickness, diviner of the future and mediator between the living, the ancestors and nature spirits — sometimes through trance and spirit possession.

Among the Limbu, the principal ritual specialists are the Phedangma (Phedangba), together with the Yeba/Yema and Samba/Samma, each specialising in particular rituals such as healing, funerary rites and the recitation of specific Mundhum cycles. Among the Rai and related groups, the corresponding figures are the Nakchhong (the community's chief ritual priest) and the shamanic Bijuwa and Mangpa. These roles are typically learned through long apprenticeship and, in many lineages, passed within families.

In everyday Kirati religious life the Phedangma or Nakchhong presides over the Ubhauli and Udhauli observances, the Nwagi first-harvest offering, weddings, name-giving and death rituals, chanting the Mundhum to call the deities and secure blessings, protection and a good harvest. Their authority rests entirely on mastery of the recited text rather than on any priestly hierarchy or ordination.

The Kirat community keeps its own era, the Yele Sambat (Yele Samvat), named after Yalambar, the legendary first Kirat king who, in Nepali chronicle tradition, defeated the Gopal (Ahir) rulers to establish Kirati rule in the Kathmandu Valley. Different Kirati peoples have their own names for the era — the Limbu call it Yele Tangbe, the Rai Yele Dong, the Sunuwar Yele Thoche and the Yakkha Yele Naamsam — reflecting a shared calendar under local names.

The Yele Sambat epoch is calculated at roughly 1779–1780 BC, worked back from the traditional end of Kirati rule and the recorded length of the dynasty. That places the era far ahead of the Bikram Sambat (Vikram Samvat) and Gregorian years: by this reckoning the Kirat year had reached the mid-5,000s in the 2020s AD (for example, Kirat / Yele Sambat 5085 was marked as beginning in January 2025). Because the count derives from chronicle traditions rather than an unbroken calendrical record, the exact year should be treated as an identity-affirming convention rather than a precise astronomical epoch.

The Kirat New Year is observed around 15 January, coinciding with Maghe Sankranti (roughly 1 Magh in the Bikram Sambat calendar) — the same mid-winter turning point celebrated across Nepal with foods such as yam, sweet potato, ghee, chaku and sel roti. For the Kirat, the day doubles as a New Year of cultural revival, marked with community gatherings, Mundhum recitation and traditional dress.

The most visible expression of Kirat Mundhum is its twice-yearly seasonal cycle of Ubhauli and Udhauli, which ties worship directly to the farming year. Ubhauli ('going up') is celebrated in spring, on Baisakh Purnima — the full-moon day of Baisakh (April–May) — as people and livestock traditionally moved to higher pastures and the planting season began; it is a prayer to nature for good crops and protection from calamity. Udhauli ('coming down') falls in early winter on the full-moon day of Mangsir (November–December), when the harvest is in and the community gives thanks and descends to lower altitudes.

Among the Rai and Sunuwar, this cycle is danced as Sakela (also Sakewa or Sakenwa). The core ritual is the Sakela Sili, a circular dance performed by men and women in traditional dress, led by a pair of dancers and set to the beat of the dhol and jhyamta (drum and cymbals). Its steps mimic the agrarian and hunting year — ploughing, sowing, harvesting, tree-felling and the movements of birds and animals — turning the whole farming calendar into choreographed thanksgiving to Mother Nature.

The Limbu and Yakkha broadly share the same two-season logic but mark it with their own observances. The Limbu celebrate Chasok Tangnam, a first-harvest festival on the Mangsir full moon whose central Nwagi ritual offers the season's new millet, rice and produce to Tagera Ningwaphuma, the ancestors and nature spirits, officiated by the Phedangma. Yakkha and other Kirati communities keep parallel rites, so that across the eastern hills the Ubhauli–Udhauli rhythm binds the whole Kirat world to the land.

Although Mundhum worship is aniconic and hearth-centred, several places carry deep Kirati sanctity. The Halesi–Maratika caves in Khotang are revered by Kirat, Hindu and Buddhist devotees alike, functioning as an ancestral shrine tied to the Mundhum. The Pathibhara / Mukkumlung ridge in Taplejung is holy to the Limbu as well as to Hindu pilgrims, and the eastern hills of Limbuwan and Khambuwan are dotted with clan and nature shrines rather than built temples.

The Limbu language has its own writing system, the Sirijunga (Sirijonga) script, attributed to the medieval king Sirijunga Hang and revived in the 18th century by the scholar-martyr Te-ongsi Sirijunga; it is today taught in schools in Koshi Province and used to publish Mundhum texts. This literary revival is part of a wider cultural resurgence: Kirat religious and social welfare associations, the Kirat Yakthung Chumlung and similar bodies now standardise rituals, publish scripture, run Sakela celebrations in Kathmandu and the diaspora, and campaign for public recognition of Kirat festivals.

This page complements Amarnepal's data-focused entries on the Kirat religion in the census and on the Rai and Limbu (Yakthung) ethnic groups, adding the belief, ritual and calendar context behind the numbers. Together they show why 'Kirat', 'Mundhum', 'Sakela' and 'Yele Sambat' have become rallying points of eastern-Nepal identity — a religion defined not by a book or a building, but by a recited scripture, a seasonal dance and a distinct sense of time.
