What Is A Chart Ruler In Astrology

Astrology lovers often mention a “chart ruler,” but what is it? In astrology, the chart ruler is the planet that oversees the person’s Ascendant or Rising Sign. It has a strong effect on their character traits and how they relate to the world around them.

The chart ruler is the energy and characteristics that the individual embodies at a base level. Everything in their birth chart is expressed through this filter. For example, someone with a Leo Rising sign will have the Sun as their chart ruler. This implies that their self-assurance, inventiveness, and leadership talents are heavily guided by the Sun’s qualities in their birth chart.

Figuring out your chart ruler can give you valuable insight into your powers, weaknesses, and bigger life plan. Analyzing its place in your birth chart can help astrologers get a clearer idea of your core identity and purpose.

It’s noteworthy that the concept of a chart ruler is based on ancient astrology practices and might not be focused on in other astrological systems. However, for those who use it, it can give important information about a person’s psychological makeup and key life themes.

Famous astrologer Robert Hand values the chart ruler in his book “Planets in Transit.” He states that observing transits regarding this ruling planet can provide incredible insight into life-changing events and personal growth possibilities.
