Georgia Stathis, a professional astrologer since 1978, demonstrates how to delineate a chart using modern rulerships -- the key to reading a chart accurately. Using the concept of rulerships assists you in refining the smaller, often unseen details in a horoscope.
Georgia taught this course at Kepler College and walks you through the process -- first comparing older rulership ideas to the more modern slant. Neither is wrong nor right. However, modern events often require modern rulerships, particularly when analyzing more mundane events and current affairs.
