Evolution happens. As the wheel of life turns, experiences shift our consciousness into a whole new way of perceiving the world around us. Most of us can look back and easily see that the person we were 10 years ago is a much different version of who we are now. How does astrology track this? Theoretically, we track it with a progressed chart. For over 350 years there has been one primary method of calculating this chart called Secondary Progressions. Surprisingly, there is a sister method to Secondary Progressions that has been hiding in the shadows all along; enter, Orbital Progressions. Orbital Progressions, the new timing technique defined and illustrated within this book, provide noteworthy data and insight. They are a "mean" calculation, tracking the constant rate of planetary revolution around the Sun, as opposed to Secondary Progressions which track the "true" movement. Whether you are an intermediate astrology hobbyist, or an experienced professional astrologer, Orbital Progressions are sure to pique your curiosity. If you are interested in predictive astrology, or understanding the current expression of your natal chart in greater depth, this book is for you. The celestial alignments within the charts presented exhibit why Orbital Progressions should be an addition to any delineation toolbox.
