There is a reason why Pluto is so feared in many astrology circles: it can do a lot of damage. And having one or more prominent Pluto aspects – meaning having the Sun, Moon, Mercury, Venus, or Mars in major aspect to Pluto (conjunction, square, opposite, sextile, trine) – means that you can potentially do a lot of damage. There is an innate destructiveness to Pluto’s energy. This is where a big part of its tremendous power comes from. When it sets its sight on something, absolutely nothing can stand in its way. With Pluto square my Sun and conjunct my Moon, I should know!
Although I do advise Plutonians to see the light and rise above the lower octave of this energy – the potential obsession with control, manipulation, vindictiveness, paranoia, etc. – I don’t think that this darkness should be discarded altogether. In fact, Pluto’s intense appetite for destruction can be used for good. Negative, toxic, and limiting things can be destroyed as much as things that are lovely and innocent and pure can be destroyed. But, to do both, a certain ruthlessness is needed.
