It is a blend of art and scientific principles. Astrology does not pretend to be a hard science, like biology. What I have learned is that using astrology to predict the WHAT in your life is not the best application. (What happened, what is happening now and what will happen.)

If you are talking about human beings, my experience suggests that it best suited for revealing the WHY in your life. That is, “why do you draw certain situations and relationships into your life. What are the unconscious beliefs that run your life?” Or, even better, “what is the musical score of your life?”
