Kirat Mundhum is the traditional religion of the Kirat peoples of eastern Nepal, principally the Rai and the Limbu, and its scripture, the Mundhum, is not a printed canon at all but an oral recitation carried by trained priests, called nakchhong among the Rai and phedangma and yeba among the Limbu, who transmit it within their own priestly lineages. This article names what the Mundhum is and does without repeating its words, which belong to those lineages rather than to any published edition.
What can be told publicly is the shape of the religion around that recitation: ancestor veneration and reverence for nature spirits tied to particular hills, rivers and forests, observed through rites keyed to the agricultural year rather than to a fixed liturgical calendar. Kirat religious identity has become an increasingly public and political fact in Nepal in recent decades, as Rai, Limbu and related communities have organized to have Kirat Mundhum recognized as a distinct religion in its own right rather than folded into broader regional categories, part of a wider movement among Nepal's indigenous nationalities to have their own faiths counted and named. The tradition remains a living one, carried forward by its priesthoods rather than by any text a reader could open.
