At the dawn of time, when God immolated himself in his own fire to give rise to creation, from the nothingness that contains everything arose the first dual manifestation: Omeyocan. Since then up to the present day, the human species has sought out that original God, and the Aztecs developed a truly profound knowledge about Him, which they bequeathed in their myths. This work of V.M. Samael Aun Weor is a true prodigy of knowledge, both about that sacred people who, in their Golden Age, approached divinity, and about the truths that they expressed in their mythology, in their mystique and in their deep respect and veneration for that Father-Mother God, and which they bequeathed in their texts and carvings in the hard stone. Prepare yourself, reader, for a journey into the past by which you will understand your present and prepare your future.
