Capricorn may be the most polarized of all the signs, for it rules practicality, which is one of the most loaded words in our language.
Loaded because since we are here to evolve our consciousness, then what is most practical is anything that will support us in that process. The problem is, if the Capricorn individual lacks spiritual awareness, then what seems to be most practical will be such things as amassing as much wealth as possible, meeting the expectations of others so that one may fit in to current social standards and hence use them to further one's materialistic ends, and in general to engage in any activity which both serves the ego and keeps fear at bay.
Capricorn is the sign most aware of what works and what doesn't, as well as the relative degree to which any technique will yield desired results. In short, Capricorn is the sign of manipulation. This is a difficult word for many people because they read negative overtones into it. The fact is that manipulation needn't be sociopathic. It is possibly to manipulate for positive reasons.
When a person has Saturn in Capricorn (one of the signs which it rules)in their natal chart, he or she is highly sensitized to how the world works, the ins and outs of social mores, and what behaviors are considered acceptable and unacceptable in various social groups and sub-cultures. All of these "rules of the game" are experienced as limitations and restrictions that may be oppressive, on the one hand, but on the other creatively worked with for the purpose of getting to wherever one is going.
Aye, there's the rub -- just exactly where is this person going? It all depends on their level of evolution and awareness of the true nature of reality. If their goal is solely to maneuver the labyrinth of the physical world in an attempt to create comfort for themselves while avoiding pain and suffering they may over time become highly adept at this. But there is never going to be true fulfillment for them until they awaken to the true goal of life.
Once they see that evolution is the key to a meaningful physical embodiment then they can access their true power, for Saturn in Capricorn is a potential master of spiritual technologies, of the ability to find and employ techniques that can profoundly further spiritual growth.
Its all about getting on with what is really and truly, in hard core terms, practical.
