A natal chart quadrant is a way of dividing up the sky into four parts. It is used to look at the planets in a birth chart and the way they interact with each other. Each quadrant is divided by two axes, the ascendant and the midheaven. The ascendant is the point of the zodiac that is rising over the eastern horizon at the moment of birth, and the midheaven is the point over the southern horizon.
The four quadrants of a natal chart are the angular houses, which are the 1st, 4th, 7th, and 10th houses. These houses represent the ego, the home, relationships, and career. The other eight houses are known as the succedent houses, and they represent the inner self, finances, health, and spiritual development. By looking at the planets in each quadrant, an astrologer can gain insight into the individual’s personality and life path.
