Every chart is chock full of information. It tells you exactly what energies are present in the person’s life. The sticky part comes when you try to pin down exactly how that energy is going to manifest. You can’t, not exactly. We are all dastardly little snowflakes, playing out our personal dramas in our own unique free-fall to earth.
If we were all good little automatons, chart reading would be a snap and all anyone would need is a good cookbook explanation of each and every aspect. Free will is a bitch. All a person can say with any certainty is that such and such energy is present and a person will tend to be or act in such a way that energy allows. Free will is one complicating factor, interacting with one’s environment, nurture, is another.
Take, for example, a plutonian chart with an emphasis in creativity and spirituality matched with a deep drive to perform. This could be seen in the chart in many ways, many combinations, 8th house, 5th house, 10th house, 12th house, Pluto, Neptune, Mars, the Sun… but much as we would wish otherwise, with only the chart for reference there is no concrete way to predict with certainty whether the individual will be creating the equivalent of the Sistine Chapel or painting themselves with poo in the confessional.
Past behavior is the best predictor for future behavior. Put past behavior together with elements of the chart that help explain motivation (what do they seek? how do they seek it?) and the picture becomes clearer. What you have right there is a model for narrowing down the possibilities of future behavior.
Life is uncertain. People are complicated. Astrology is fantastic for narrowing down what is possible and pinpointing the energies available to any given individual. Look for what is possible in a chart, what is probable. Rather than painting oneself into a corner, start in the corner and paint out.
