In some traditions, animal forms of spirit helpers and guardian spirits predominate. In North Asia, these are in most cases anthropomorphic spirits of ancestors and deceased shamans who can take the form of an animal.
Spirit helpers play an essential role in the beginning of a shamanic session, that is, in the preparation of shamanic journeys. Usually their presence is manifested in the shaman's imitation of his spirit-helper's cries or behavior.
In Nanai, even worms that “eat” a shaman's body during his sickness are transformed into spirit-helpers. They are represented in the form of snakes. A shaman inherits some of his supernatural helpers from his predecessor in the clan. In Nanai shamans, the very first spirit-helper was the spirit Edekhe, who came to a shaman “through kinship”.
The Golds (Nanai) make a clear distinction between the guardian spirit ayami, who chooses the shaman, and the subordinate spirit-helpers siven, whom the ayami himself hands over to the shaman. Each shaman always has several closest spirit-helpers. They appear in the period of his formation.
The animal-helper of Buryat shamans is called khubilgan, which can be translated as “metamorphosis” (from khubilhu - “to change”, “to acquire a different form”). In other words, the animal-assistant not only allows a shaman to reincarnate, but is in a sense his “double”, sub-personality, one of the souls of the shaman, “soul in the image of an animal” or, more precisely, “soul-life”. A shaman fights in the form of an animal, and if his animal is killed in the fight, the shaman is greatly weakened and may even die.
The number of spirits “belonging” to a shaman depends on his “power”. Great shamans have many of them, and weak shamans have only a few.
Shorian shamans, like Kumanda shamans, use different “horses” to travel to Ul'gen and Erlik. Mythical birds, the supernatural creature Tailyk, similar to ermine, pike and burbot also serve as riding animals.
Part of the spirit helpers guard their master during a ritual, part leads the exploration and search for the soul stolen from a client, and part serves as a means of transportation: carries the shaman, carries the sacrifice to the spirits and the found soul, etc.
The first time that a person has a spirit helper, he is informed by a shaman during his sickness or journey. This spirit comes from the sky, from the place where there is fur. Therefore, the spirit always knows good places in the taiga and informs the hunter about them in a dream.
