Although it's been around for more than 5,500 years, astronomers say that we've learned more than 90 percent of what we know about the universe in just the last 50 years. Of this body of knowledge, a disproportionate amount has been acquired in the past decade, with each new year yielding more information than the last. The Complete Idiot's Guide to Astronomy, Third Edition, covers these new advances and discoveries and is repositioned to focus more on exciting, cutting-edge cosmology topics and less on backyard astronomy.

The Toltecs were an ancient society who lived in the central valley of Mexico. Their knowledge of science, art, and the spirit was amazingly advanced, and it led them to create a system of teaching that required enormous discipline and willpower. Focusing on the mind, the Toltecs developed a spiritual philosophy that incorporated the beauty of many esoteric teachings, forming a perfect model for transcendence. They believed that humans live in a world of dreams, and the way they dream places limitations on their lives. By changing those dreams, and reprogramming our minds, the wisdom of the Toltecs can lead us to the self-love and respect that are the keys to personal freedom. In The Complete Idiot's Guide to Toltec Wisdom, readers can travel through life with the knowledge of the Toltecs, taking charge of their lives and becoming fully aware for the first time.
