Death, Re-birth, Change of Spiritual State. The Underworld. This day brings the energy of life and death - descending into the Underworld, to walk the dark night of the soul so that resolution and transformation can be reached, creating new life. The shadow side of the energy is to become lost in the darkness and wander as a tortured soul trying to find the light again.
This blog gives my own interpretation of the days of the "Tzolkin" Mayan Calendar.
