The eternal voyage of the Sun between the heavens and the underworld.
The Xibalbá or underworld was considered the place where the ancestors live eternally and the place where the Sun descends to every day to fight against the nine Lords of the Night or Bolontiku, commanded by the merciless Ah Puch. But the underworld is not only a place of death, it is the space of the universe where water comes from and where seeds germinate, the elements that give life to the inhabitants of the Earth and, thus, the place of rebirth.
Every day the Sun god wins over the forces of the underworld and the gods of death to rise, again, from the East and do its journey across the thirteen levels of heaven to provide light to mankind. In the same way there are nine Lords for each level of the underworld, the heavens are ruled by Oxlahantiku, which is one and thirteen deities at once. Likewise the thirteen levels, conceived as steps, are ruled by Itzamna, the supreme deity, the Sun at its zenith. The heavens is also the place where the gods of rain and the goddess of the Moon live.
