Pluto retrograde represents a conquering of the past and rebirth. As Pluto is retrograde in around half of all birth charts, it is clearly less significant than the retrograde motion of other planets. Nevertheless, here Pluto's transformative power works in reverse by focusing on unseen processes rather than on that which is visible. When this is working well, it provides great energy to the inner dynamics of the personality so that the underlying spirit can express itself more freely. The power of an unbridled Pluto can be challenging for many people, and is often suppressed, only to eventually erupt as anger, self-condemnation and other destructive emotional expressions. Thus the challenge here is to control and focus Pluto's power, and to learn to bend it to one's will and personal progress.
