Sun in the 7th House: Meaning and Tendencies
What Sun signifies
Sun is the kāraka of ātma (the soul), vitality, authority, the father, and one's sense of dignity and purpose (BPHS Ch. 3 (Graha significations); Phaladīpika Ch. 2). Sun's signification travels wherever Sun sits. In the 7th house, Sun meets marriage specifically — the pairing this page is about, house by house across every one of Sun's twelve placements. One more constant travels with Sun into every house: classically Sun is a natural malefic (pāpagraha), so a Sun placement is read for the strength and heat it brings, not automatic ease.
What the 7th house governs
The 7th bhāva is classically read as the house of marriage, partnerships, contracts, and public dealings. By quadrant, the 7th house is a kendra (angular) house: BPHS's shadbala gives kendra houses the most of the three classes' positional strength (sthāna bala). That quadrant strength is the 7th house's starting baseline. Its own sign and its lord shape marriage first; anything aspecting the 7th house adds more on top. Sun enters this picture only after that baseline is already set.
Sun in the 7th house
When Sun occupies the 7th house, Sun's significations — ātma (the soul), vitality, authority, the father, and one's sense of dignity and purpose — express through marriage, partnerships, contracts, and public dealings. Because the 7th house is kendra, results here tend to read as outward and prominent — the way kendra results classically show. Sun does not override the 7th house's own quadrant nature; it colours it. The sign the 7th house falls in for you, Sun's own dignity there, and what aspects the 7th house all decide how this actually plays out.
This house's own significator
The 7th house's own naisargika kāraka (BPHS 32.34) is Venus — not Sun. So the 7th house is read through two grahas at once: Sun, sitting here, and Venus, who owns it by nature. Marriage in the 7th house leans on both — Venus's own placement completes what Sun alone cannot say.
How to read this
Sun in the 7th house is a classical tendency, not a verdict — read it that way. What actually decides how marriage plays out: the sign the 7th house falls in for you. Also decisive: what aspects the 7th house, and whether a Sun daśā or antardaśā is running for you right now. A page about the 7th house in general cannot see either of those two things — your own chart, with your real 7th house, can.
