The Kultrun is the symbolic microcosmo of the Machi and the Mapuche Culture, in which it takes the shape of its particular spiritual conception of the universe.
Its drawn membrane represents the cosmic superstructure and its diverse inmaterial components, representing like the four divisions of the square earth platform, oriented according to the four cardinal points, beginnig in the East, up to the land of the Four Places, or Meli Witran Mapu. On the other side, the wooden pot of the Kultrun, with the symbolic objects introduced in it, represent the cosmic and earthly infrastructure with its diverse material components.

According to the Mapuche belief, from this moment on the voice and the energy of the owner will remain forever inside the Kultrun, creating like an identification of the Machi with the instrument, that will symbolize her own voice and her own shamanic power.
Once completed the introduction of the Machi´s voice, the instrument is closed strongly, tying the edge.
