Traditional beliefs of the Yukaghirs involve cults. There were cults of the tutelary deities, the supreme being Qoil' (merged with the Christian cult), game animals (especially elk), bears; cults of fire, ancestors’ spirits. They worshipped sacred stones that embodied the feminine. Later, along with the other beliefs, there were the male tutelary deities and the guardian spirits of animals, which are associated with a number of prohibitions and hunting rites.
The Yukaghir’s idea of a human soul was rather complicated. They believed in three souls. One of these, after death, goes to the Kingdom of Shadows. Another becomes a double that only shamans can see, which, after death, inhabits a newborn. The third soul is a shadow, which is also inherent in inanimate objects.
The Yukaghir had developed concepts of the universe’s division into upper, middle and lower worlds connected by the river. Mythological legends Nganasan are centered around the creation of the world, established according to the will of the "Mother of everything that has eyes " and "God of Earth" Syruta-ngu; their son, man-deer, becomes the first inhabitant of the Earth and protector of the people.
Customs associated with fire played an important role in the spiritual culture of the Yukaghir: it was forbidden to share fire from the hearth with outsiders, to walk between the hearth and the head of the family, etc.
