The author of The Four Agreements summarizes Toltec knowledge of the future, details the entrance of humanity into the Sixth Sun, and divulges the insights necessary to make the next step in evolution. Ruiz shows that we possess the power to replace fear with a new dream of Heaven on Earth, and that the survival of humanity rests with our Intention. It is in our power, he says, both individually and collectively, to focus our intention to create the future we desire.
