Retrograde means that, from the Earths viewpoint, the planet in question visually appears to pause, then begin moving backward through its normal path across the sky. Of course, the planets dont actually change direction, but since the Earth is considered to be the center of our universe in geocentric astrology, which is what we use in this guide, we only care about our perspective from here." "When a planet goes retrograde, the issues reflected by that planet as it travels back through the sign (or signs) tend to have you revisiting the experiences you had when it moved across that point in its original forward movement." http://www.inlightimes.com/archives/2008/10/retrograde.htm Read the entire 2nd paragraph at the above link. Very interesting.
