According to the Toltec/Aztec calendar, which describes larger cycles of time or "Suns" than the Mayan calendar, humanity has been in a transition that started in 1991, moving from the 5th to the 6th Sun. During this shift the influence of both Suns is equally present, as is the case when the seasons change. This shift is also a shift in human consciousness, in our understanding of how we relate to the whole of existence. The custodians of this 1,460-year-old uninterrupted oral tradition now reveal this ancient wisdom to the world, in written form, for the very first time. This book contains breathing exercises, poses, and other ancient practices that are based on cosmic mathematics that show us how to realign ourselves with the universe, Earth, and the elements, and with our highest nature so that we can take responsibility for the sacredness of life and move successfully through this transition from one Sun to the next.
