The Lower world is completely similar to ours, with the only difference being that its inhabitants have only one soul, while humans have five. The soul called ami, which is responsible for breathing and body warmth, is absent in them, which is why the inhabitants of the Lower world are cold, and black blood flows in their veins. Some of the inhabitants of this world are also human souls called sane, waiting for reincarnation in our world. The sun and moon in the Lower world are less bright than in ours. According to the beliefs of the Sami people, the reason for this is that their shape is a hemisphere, not a sphere like ours. The Lower world has forests, mountains, settlements, and even its own shamans.
Erlik, the son of the Father - Heaven, rules over this world. He has power over souls, over where and when they will reincarnate in our world. Shamans usually turn to him when they return souls that prematurely went to the Lower world - before the death of the physical body. Apart from these cases, people enter the realm of Erlik only after death.
There are many paths that lead to the Lower World and back. One of them is a journey along the World River, flowing there. This entrance is guarded by Mongoldai Nagts, who does not allow souls whose bodies are still alive to pass through it. Sometimes a living person's soul manages to slip through this entrance, and it must be returned before its absence causes great harm. The World River has many rapids, and it is very risky for a shaman to travel alone. When a shaman dies during the retrieval of someone's soul from the Lower World, it is said that the journey was too dangerous and his soul was lost in this world. It’s also possible to enter the Lower World through caves, whirlpools, springs, as well as through one of the numerous tunnels through which the inhabitants of the Lower World enter ours.
