"Based on the divination tool known to ancient Mesoamerica as the Cross of Quetzalcoatl, or Tonalpohualli, this interactive oracle functions as a sacred mirror for self-exploration and soul transformation. It consists of 20 Tonalpohualli cards, calendar signs that represent archetypal situations in life, 13 Ruler cards depicting the main deities and sacred principles of the Toltec religion, and a book. The artwork is from original 16th-century codices. In addition to card interpretations, the book contains over 200 exercises and practices."
