The Aonikenks believed that the old people were reincarnated into children. When a young person died, his or her soul wandered with no destiny, prisoner on earth, until completing the necessary time to grow old.
Due to this animist worldview, they buried their dead with personal objects, weapons and food. They believed that, to reach the other world, the dead would ride their mares, thus, upon their death, their animals were sacrificed.
The deceased person was introduce by their relatives into a quillango or guanaco cape, along with his or her silver objects and favorite weapons. It was then sealed, sewing the edges together. The person was buried in the fetal position, facing east and covered with heavy rocks.
The Aonikenk preferred to bury their dead far away from the community, on the hilltops or tchengue.
