The Aztec Book of Destiny summarizes traditional Mesoamerican beliefs about the spiritual nature of time and its influence on one's personality and fate. The ancient Aztec, Toltec and Maya believed that the day of birth, as defined in their sacred calendar, affects destiny, and this philosophy has guided their daily lives for more than 3000 years. This book condenses the scattered and disparate literature about these beliefs into a fun and informative narrative, but it goes far beyond what academics and popular authors have published to date. The author presents a unique perspective shaped by the wisdom of a traditional calendar-keeper he met in Mexico in 1973. The book's message is that the calendar is not simply an ancient and forgotten curiosity - it is as relevant today as in ancient times. The majority of the book projects the timeless Mesoamerican philosophy into contemporary Western society encouraging introspection and self-awareness.
