ERIN SULLIVAN 
Retrograde Planets [EPUB ebook] 
Traversing the Inner Landscape

"Geocentricity might well be egocentricity"- the phenomenon of retrograde motion is based on our Earth-centered view of the solar system, but the movement and cycles of retrograde planets are based entirely on the apparent motion of the Sun through the zodiac. Sullivan organizes and explains retrograde motion from a systems-viewpoint- the system of the Sun and planets- and interprets retrograde planets natally, by progression, and in transit.
