Pluto’s influence is subtle, yet very very powerful. Pluto represents deep psychological processes that can drive one to control or gain power over some part of her life. These drives are very dangerous when they remain unacknowledged, in the unconscious mind. When this drive is brought into the conscious mind where it can be understood and integrated into the personality, it indicates a healthy self-control and ability to heal others.

Pluto takes 250 years to complete a cycle. The time he spends in each sign varies, because his orbit is elliptical rather than circular. He spends between 12 and 30 years in a single sign.
