What Sun in the 7th house means
The Sun represents your essential self, your vitality, and where you seek recognition. The 7th house governs committed relationships, marriage, business partnerships, and open enemies. With the Sun here, you are often drawn to partnership as a primary way to express who you are. Your identity is shaped through interaction, and you learn a great deal about yourself by observing others and how they relate to you. You may feel most alive when you are collaborating or sharing your life with someone important.
