Proto-Uralic religion
Elements of a Proto-Uralic religion can be recovered from reconstructions of the Proto-Uralic language. == Soul dualism == According to linguist Ante Aikio, although "evidence of immaterial culture is very limited" in the Proto-Uralic language, "a couple of lexical items can be seen as pointing to a shamanistic system of beliefs and practices." The concept of soul dualism, which is widely attested among Uralic-speaking peoples, probably dates back to the Proto-Uralic period: the word *wajŋi (‘breath-soul') designated the soul bound to the living body, which only left it at the moment of death, whereas *eśi (or *iśi, *ićći) referred to the 'shadow-soul', believed to be able to leave the body during lifetime, as when dreaming, in a state of unconsciousness or in a shaman's spirit journey.
