Sometimes they are seated, surrounded by a sky-band which gives the ruler a halo of celestial authority. Rulers also liked to associate themselves with auspicious gods of the sky such as the Sun God, and Maya rulers and priests in real life often "clothed themselves with the heavens" by dressing in the pelt of the jaguar, whose spots were taken to represent the stars. The Maya believed that the gods guided the Sun and Moon across the sky.
Even in the darkness of night, the Maya believed that the Sun and Moon continued to journey through the Underworld, threatened all the way by evil gods who wanted to stop their progress. For this reason, the Maya believed that the heavenly bodies needed human help, which was provided through sacred rituals such as self-mutilation, torture, and human sacrifice. To the Maya, offering this help was simply the price to be paid for the continued survival of the universe.
Death from such rituals was a privilege, and conferred immortality on those who died, or who offered themselves as victims. The repeating cycles of creation and destruction as described in Maya mythology were a reminder of the consequences if humans neglected their obligations to the gods. Humans had an inherent responsibility to the gods who made humanity's continued existence possible.

This was seen as a frightening time when the gods and other forces of creation and chaos would do battle in the world of mortals, determining the fate of all earthly creatures. The planet Venus was particularly significant to the Maya; the important god Quetzalcoatl, for example, is identified with Venus. The Dresden Codex , one of four surviving Maya chronicles, contains an extensive tabulation of the appearances of Venus, and was used to predict the future.
The Maya also went to war by the sky, again triggered by the planet Venus. Venus war regalia is seen on stelae and other carvings, and raids and captures were timed by appearances of Venus, particularly as an evening "star".
Warfare related to the movements of Venus was, in fact, well established throughout Mesoamerica. Maya calendars, mythology and astrology were integrated into a single system of belief.
