Some of you may have heard the term “Cusp” because you were born at the end of one sign and really close to the beginning of another.
This is NOT what I’m referring to here.
This short article is about the cusps of the houses, which are instrumental in one’s interpretation of the entire birth chart.
As you can see from the chart above the house cusps are circled in red. I use what’s called Whole sign houses, so the cusp is at 0 degrees at the beginning of the house. This is NOT the same in every house system as you’ll see whenever you start to experiment. For example, in the Campanus system of house division, the cusp actually marks the center of the house.
In most house systems, the cusp is viewed as the doorway or entry way into the house, so the sign on the cusp, along with its planetary ruler says a lot about the optimal approach to the affairs of that particular house.
In fact, the planet that rules the sign on the house cusp is known as the “ruler” of that house.
It helps to look at the ruler of a house as being the “landlord” and planets in the houses as being “tenants“.
No matter who that house is occupied by, the ruler sets the terms and conditions of that house and the occupants have to find the most effective strategies that they can, to live in accordance with those terms and conditions.
