Understanding Planetary Rulership

What is planetary rulership?

Planetary rulership is an essential concept in astrology that associates each zodiac sign with a ruling planet. This concept suggests that each planet has a unique influence on specific signs and governs various aspects of an individual’s life. Understanding planetary rulership allows us to gain deeper insight into ourselves and the dynamics of our birth charts.
