Where Jupiter showed process, Saturn shows structure. Saturn is the ruler of Capricorn. Its placement and aspects indicate how structure is perceived either as limitation and restriction that keep you from pursuing your desires or as a container in which you can lead an orderly and productive life. On the whole structure is a good thing. The structure of bones allows us to move about and stand erect. Our skin provides a container without which we would surely die. It is how we perceive the container and what we do with it that makes all the difference.
As Saturn moves through the signs, its cycle defines major life changes. Around age seven you develop a new sense of personal responsibility, at about 15 you become a young adult, able to use abstract thinking in your decision-making process. At age 21 you become an adult in the eyes of the law, and around age 28 to 30 you experience your first Saturn return (It takes Saturn 28 to 30 years to go through all of the signs one time), and you undergo a shift from an extended growth period into an extended productive period. This structure is more or less the same for everyone.
The sign and house placement of Saturn indicate how you can best pursue your career, whatever that career may be. Should you start out owning your own company Leo style, or should you undertake humanitarian goals Aquarius style? By following Saturn’s indicators you can plan a career course that allows a steady development.
Saturn provides a barometer for you in the form of feedback. Sometimes you feel limited in what you can do, and you can use this as feedback about what educational opportunity to pursue. Sometimes you are afraid of the next step, and you can use this fear to show you where to seek emotional support. You will experience authority and responsibility in your life in constructive or destructive ways, based on where Saturn is found. Saturn can become your inner teacher and guide, as well as a timer for major changes throughout your life.
