Yer Tanrı is an Earth deity in Turkish and Altaic folk belief and mythology, also called Yertengri or Certenger.
In the Yakut heroic epics, the valiant people who will be invincible in the future are frail and weak in childhood.
This is the meaning of shaking crazy people into wells even today in some regions of Anatolia.
However, sometimes they describe her as a white-haired woman living in the trunk of a large beech tree.
The branches of this tree reach up to the sky, which is owned by the spirit that sends people the most beautiful horses as gifts.
When young girls become brides, they take their baskets (that is, their guardian spirits) with them, and the origin of the concept of dowry is probably based on this practice.
