The 1st House is Self; the 7th House is Other. These two form the primary axis of your life. The 7th House represents the qualities we disown in ourselves and project onto others—which is why we are attracted to them. We seek in a partner what we lack in ourselves.
The Descendant (DC): The cusp of the 7th House is the Descendant. This point describes exactly what you are looking for in a long-term mate. It is often the opposite energy of your Rising Sign.
Contracts & Enemies: Surprisingly, this house rules both marriage and open enemies (lawsuits, rivals). Why? Because both require an intense one-on-one focus. A spouse and a rival are two sides of the same coin of intimacy.
Angular Power: As an angular house, planets here are highly visible. They show how you relate to the public and how you compromise.
