The significance of this day
Aztec facts
Aztecs named a newborn child after its day (tonalli) of birth. The elemental forces ruling over that day strongly characterize a person and its destiny.
Day 1 - Ozomahtli is influenced by the Cihuateteo.
1-Ozomahtli is the first day of eight in a row specially associated with pulque, the alcoholic beverage made from the fermented sap of the maguey (agave) plant (octli).
Day Ozomahtli (Monkey) is governed by Xochipili, the Flower Prince, as its provider of tonalli (Shadow Soul) life energy. Ozomahtli is a day for creating, for play, for celebrating. A good day for lightheartedness, a bad day for seriousness. Ozomahtli is a warning about how easily the noble person can be trapped by the lures of public life.
The thirteen day period (trecena) that starts with day 1-Ozomahtli (Monkey) is ruled by Patecatl. The 13 days of this trecena are influenced by the quest for cures of all the various ills that befall us: the quest to obtain power that can overcome misfortune lies at the heart of the warrior's purpose. The transformation of poison into medicine, and evil into good, is an art whose expression must be tailored to the field of battle. These are good days to fashion a war shield and collect articles for your medicine bundle; bad days to allow infections to fester.
