Hi Carol Ann,
I’m so glad you wrote, rulership is so very interesting, even now I continue to
learn new things about it.
Were to begin with rulership?
Make sure you are using a wheel that has the cusps marked with equally spaced lines. There are wheel models that have visually equal houses, the actual number of degrees per house can vary. This is the easiest wheel to use. Visually it is the best to work with, and although the number of degree per house may vary, it is a true representative of the horoscope.
Rulership is really one of the coolest things, and once you get a handle on it it can really change the way you view a horoscope.
