Kirat Mundhum: Paruhang, Sumnima & Yuma Sammang Creation Myths

Mundhum (also written Mundum or Muddhum) is the ancestral oral scripture of the Kirat, an umbrella term for a family of indigenous peoples of eastern Nepal, Sikkim and the Darjeeling hills, most notably the Rai (Khambu), Limbu (Yakthung/Subba), Sunuwar (Koits/Mukhia) and Yakkha (Dewan), along with the Dhimal and Hayu. In the Kirati languages the word Mundhum is commonly glossed as 'the power of great strength,' reflecting its status as a living body of sacred knowledge rather than a single fixed book. It is sometimes referred to as the Kirat Ved.

Unlike scriptures preserved in a canonical manuscript, Mundhum was transmitted for centuries by memory and voice. It is a vast collection of diverse oral narratives that address the creation of the universe, the origin of human beings, animals and plants, the migrations of clans, genealogies, and the rules for living. Because it carries myth, history, cosmology, ritual instruction and customary law together, scholars describe Mundhum as functioning simultaneously as scripture, chronicle and legal-moral code for the Kirati world.

The religion built around Mundhum is called Kirat Mundhum, Kiratism or Kirat Mundhum; among the Limbu the same tradition is known as Yumaism (Yuma Samyo). According to Nepal's 2021 national census, about 924,204 people, or roughly 3.17 percent of the national population, identified their religion as Kirat, making it Nepal's fifth-largest religious group after Hinduism, Buddhism, Islam and Christianity.

Ritual specialists and scholars typically divide Mundhum into two great parts, Thungsap and Peysap. Thungsap Mundhum is the older, purely oral layer: an epic composed and chanted in verse and song by learned bards and priests known among the Limbu as Samba, and transmitted before writing existed. Peysap Mundhum is the more codified, 'book-like' body of religious material, and it is conventionally described as having four parts.

The four parts of Peysap Mundhum each carry a distinct subject. Soksok Mundhum holds the creation narratives, the beginning of humankind, the origin of sin and of evil spirits such as envy, jealousy and anger, and explanations for death. Yehang Mundhum tells of the first human leader who gave people rules for marriage, arbitration, purification and worship, guiding society from an animal-like state toward order. The remaining parts (variously named, including Sapji/Sap and a section on the great flood and the splintering of languages) carry migration, genealogy and purification rites for birth and death.

This structure is why Mundhum is not treated as 'mythology' alone by its practitioners. The same verses that narrate how the world was made also lay down customary law, the correct sequence of a wedding or funeral, and the moral consequences of wrongdoing, so recitation of Mundhum is at once a religious act, a history lesson and a statement of communal law.

Among the Rai (Khambu), the central creation myth is the union of Paruhang, the sky god embodying the celestial and masculine principle, and Sumnima, the earth goddess embodying the terrestrial and feminine principle. Sumnima is revered as Mother Earth and ancestral mother, while Paruhang is the Sky God; together the pair are worshipped as the supreme deity Sumnima-Paruhang. Their names carry local variants (Sumnima is also called Hengkhamma, and Paruhang appears under other regional names).

In the best-known telling, Paruhang looks down from the heavens, is captivated by Sumnima's beauty on earth, and courts her, sending a golden comb as a token of love. Their eventual marriage and offspring symbolise the fusion of sky and earth from which the natural order, the seasons and agricultural abundance flow. The myth thus encodes an ecological and moral vision in which human life depends on the balanced relationship between heaven and earth.

The Rai narrative continues into the human age through the figure of Hetchhakuppa (also linked to the name Raichhakule), remembered as a culture-hero associated with the beginning of the agricultural era in Kirati-Rai history. In this way the Sumnima-Paruhang cycle moves from cosmic origins to the founding of settled human life, giving the community a shared account of where its people, its farming and its rituals came from.

For the Limbu (who call themselves Yakthung), the supreme figure of Mundhum is Yuma Sammang, the great mother goddess, whose name is understood to mean 'Grandmother' or 'Mother Earth.' She is closely identified with, or paired with, Tagera Ningwaphuma (also written Ningwaphumang), the unseen, formless creator and source of all wisdom. Because of Yuma Sammang's centrality, the Limbu strand of the tradition is often called Yumaism or Yuma Samyo.

In Limbu Mundhum, creation involves this supreme wisdom-giver bringing forth the world and shaping the first humans. A widely cited account describes the creator fashioning people only after earlier attempts (using materials such as gold and silver) failed, finally succeeding with a mixture of earth, ash and other natural substances animated by the sky, an origin story that stresses humanity's kinship with the soil and the natural world.

Yuma Sammang's worship is bound up with instruction: the Mundhum records her guidance to humanity and the origin of sacred rituals. Since 2018 in particular, Limbu cultural and religious organisations have campaigned actively to restore and standardise Yumaism, its priesthood and its script, part of a broader indigenous movement to reclaim distinct Kirat religious identity.

Mundhum survives because it is performed. It is chanted from memory by hereditary ritual specialists whose titles differ by community: among the Rai the tribal priest is the Nakchhong, while Limbu practice recognises a range of specialists including the Phedangma, Yeba, Yema (Yuma), Samba, Samma and Tutu-Tumyahang. Each has particular ritual roles, from healing and exorcism to conducting rites of passage and reciting genealogies.

These priests recite Mundhum at births, marriages, deaths, healing ceremonies and seasonal festivals, matching specific portions of the scripture to each occasion. Because the words are believed to carry power, correct recitation is itself the ritual: the priest re-tells the origin of the world and of the rite being performed, situating the individual event within the whole Kirat cosmology.

The Limbu also possess their own writing system, the Sirijunga (Kirat-Sirijunga) script, historically associated with the 18th-century Limbu scholar and reformer Sirijunga, which is used today to record Mundhum and the Limbu language and is taught in cultural-revival programmes. Its use is part of the same effort that has produced printed Mundhum compilations, ensuring the oral tradition is preserved alongside continued live performance.

Mundhum is most visible to outsiders during the great seasonal festivals of the Kirat, which express its nature-centred cosmology through communal dance and worship. The Rai celebrate Sakela (also spelled Sakewa), observed twice a year: Ubhauli in spring (around Baisakh) when people move and pray for a good planting season, and Udhauli in autumn (around Mangsir) giving thanks for the harvest. The Sakela Sili dance mimics birds, animals and farming actions, dramatising the human bond with nature that the creation myth teaches.

The Limbu mark their own calendar of Mundhum-based festivals. Chasok Tangnam, a harvest thanksgiving offered to Yuma Sammang and the ancestors, is celebrated around the full moon of Mangsir (Mangshir Purnima), while Yokwa Tongnam is observed in the spring. Sunuwar and Yakkha communities keep parallel Ubhauli and Udhauli observances, so that across the Kirat world the same twin rhythm of ascending and descending seasons frames the ritual year.

In each case the festival is not merely a folk celebration but a public performance of scripture: priests recite the relevant Mundhum, offerings are made to the earth mother and ancestors, and the community re-affirms the moral and ecological order that the creation myths describe.

The Kirat are not the only Nepali communities with rich indigenous cosmologies, and Mundhum is best understood alongside its neighbours. The Tamang and Gurung of the central hills preserve traditions rooted in Bon, the pre-Buddhist Tibetan religion, blended over centuries with Tibetan Buddhism. Their societies maintain specialised shaman-priests, such as the Gurung Poju (Pucu), Ghyabri (Klhepri) and Klihbri, who conduct healing, agricultural and elaborate death rituals, even as Buddhist lamas now perform many life-cycle rites; these oral shamanic recitations parallel Mundhum in preserving genealogy and cosmology outside written canon.

In the Terai and western hills, other indigenous peoples keep their own legend traditions. The Tharu, among the oldest communities of the southern plains, and the Magar, one of Nepal's largest ethnic groups and long famed for its shamans (jhankri), each transmit distinct origin stories, deities and ritual repertoires through oral performance rather than a single scripture. While these traditions are theologically separate from Kirat Mundhum, they share its core features: nature veneration, ancestor worship and a hereditary or vocationally called ritual specialist as the keeper of memory.

Seen together, Mundhum and these neighbouring systems illustrate a wider truth about Nepal: beneath the country's dominant Hindu and Buddhist framework runs a deep stratum of indigenous, orally transmitted religion in which creation myth, history and moral law are one and the same tradition.
