Those with Sun square Pluto are very passionate, and sometimes dangerously so. And this very very very passionate nature may refer to interests about work, music, literature, religion, politics, for a woman or a man. When they are involved in something there is a great use of emotion, and they become attached to a belief a person or an idea. A lust for something, and usually intense longing for some kind of fulfilment is present. These individuals have a penetrative quality to them and they can truly master themselves. It is rare for these people to make a neutral impression on others, and many of their personal relationships need to contain the big three - passion, intimacy and commitment.
The usual interpretation of Sun square Pluto suggests there will be far reaching changes and the chance for regeneration, transformation and rebirth. And there are some heavy interpretations for the meaning of such crisis and change in the individual's life. For example, Astrologer Lyn Birkbeck has this to say on the meaning of transformation...
" If this seems 'unfair' it is only because you are ignorant of the chain of events, of previous actions or failures that have been amounting to Critical Mass over some time. Sooner or later comes a time and a circumstance where there is no room for equivocation or compromise. It takes concentration of experience to force you to concentrate, and look more deeply into the root causes of things."
Sun Square Pluto - Exposes the Individual to the Darker Aspects of Life
Sun-Pluto people are concerned with the mysteries of existence and they love to look deep for the answers. And usually this very passion for life gives a depth of knowledge. The square aspect formed between the Sun and Pluto creates weighty problems around the Sun principle, ie. identity, the men in the individual's life, and self-expression. The nature of the Sun is to radiate, shine and shed light on all things. The Sun square to Pluto aspect exposes the individual to the darker aspects of life - taboos, abuse, violence, mental illness, power and control.The square aspect is charged with tension and a lot of energy is released.
The square aspect develops and strengthens the personal will, because that is what is needed to meet its demands. Lack of skills or resources to meet any current crisis may be a cause for frustration or concern. The aspect implies direct application of energies to accomplish immediate ends. The energies or types of actions symbolized by the planets involved will be applied forcefully...The square's mode of action is abrupt and creates discomfort, which is a spur to action. The square aspect produces turning points in the life, critical junctures. This aspect is one of obstruction, disruption, imbalance, frustration of desire (or self-realization through heroic struggle) and is the most dynamic of all aspects. It allows for the building of frameworks or structures on which the future will depend. By Wikipedia
Sun square Pluto can remain deceptively self-controlled for long periods of time, and sometimes it can be very difficult to really get know them, and even knowing them intimately doesn't always give complete access as there are doors that will always remain hidden. In fact, these individuals are viewed as extremely complex and difficult to analyse, and they have a fear of not being fully in control. According to astrologer Sue Tompkins these types take great pains to hide themselves.
Sun square Pluto people may be obsessed about achieving their goals, and they can be just as competitive as Sun-Mars types, but they are less open about it. Often the wielding of such a concentrated will-to-power helps them achieve their objective. Sun-Pluto have the feeling that they are invincible and will go to any limits to get what they want. Losing almost feels like a death, they invest everything in winning. The more evolved type of individual usually expresses good sportsmanship.
Getting close to people often brings up some deep complexes about trust issues and forming bonds is sometimes difficult because of the fear of abandonment, death, and destruction. Unresolved feelings of inner turmoil in this personality can result in overreaction, and seemingly trivial events trigger explosiveness. Another issue for these individuals comes in the form of authority. The Sun-Pluto person may have feelings of hatred towards those in positions of power. They may use manipulation and psychological pressure in an effort to gain the upper hand. Many lessons involve that of personal power and this involves the confrontation with one's own darkest shadow. Sun-Pluto types have incredibly strong desires to know themselves and their deepest psychological recesses.
Sun-Pluto people may also struggle with the feeling of being worthy and self hatred may be an issue. Until they are able to accept themselves then they will remain feeling bad, unattractive, unworthy and unlovable at their core. The father often plays a significant role in the individual's solar development. The father may be an overwhelming personality who is able to completely control the child, and they may have felt they had no "space" in childhood or were unable to breathe around this person. The feeling of being invaded is often a common one. A child with this contact may feel helpless and bullied by his sheer presence. The occurence of the death of father, or of a loved one, is another feature. The bond with the father is also often a very close one and he inhabits an important place in the individual's psyche.
