The Seventh House represents one-on-one relationships, marriage, business partnerships, and significant others. It reveals what you seek in others and how you navigate cooperation versus competition.
In astrology, the Seventh House is sometimes called the house of marriage, but its deeper teaching is more subtle: it is through our primary relationships that we encounter the parts of ourselves we have not yet integrated. The partner, in this sense, is always a mirror. Who we choose and how we love reveals more about our inner world than almost any other factor in the chart.
