The significance of this day

Day Cipactli (Crocodile) is governed by Tonacatecuhtli, Lord of Nurturance, as its provider of tonalli (Shadow Soul) life energy. Cipactli is an auspicious day, signifying advancement and honor. It depicts energy and work, rewards and recognition. A good day for beginnings.

The thirteen day period (trecena) that starts with day 1-Malinalli (Grass) is ruled by Mayahuel, Goddess of the Maguey and Pulque. These are 13 days of intoxication, infatuation, excitement and passion: it is a time of excesses, when moderation is impossible, and so is often a time of disastrous consequences. This trecena signifies those times when we are incapable of protecting ourselves from high emotions. It is a time when affairs of war and affairs of the heart are born without thinking. These days are clouded in confusion: only the most self-disciplined warrior can suffer an excess of success without incuring sudden loss. These are good days to bind the community together; bad days to sow discord and discontent.
