In riddles to designate the soul of a living person, the terms “soul-blood”, and “soul heart". This soul served as a messenger: it was released at the sacrifice of bloodshed. The "shadow-soul", during the life of a person, was passive, and after his death was separated from the body, turned into a "ghost", the soul of the deceased, and descended into the cave of the underworld. in riddles, the “ghost” of the deceased is also called pixan and poe (“covered, tied, wrapped”: both terms, etymological synonyms and euphemisms, meant a swaddled and bound corpse; the term xib, another term for the ghost of the deceased, appears in riddles in the meanings of “old man ” and “ancestor”). The deceased goes to where he will “spew his shadow” (the soul-shadow leaves the body), where he will be “visible at noon” (In the fire of the middle of the day), where he will “become a child again” (i.e. e. will gain a "second childhood") and "will crawl" again. By this, it means that the soul-shadow / ghost, retaining the appearance of a living person, descends into the “place of purification", into the cave - the underworld ( "Eformulas of Rebirth") on memorial vessels of the 5th-9th centuries), where it is cleansed in order to finally "liberate dress" and "fly away" for rebirth.
