Rahu in the 7th for a Sagittarius Lagna

For a Sagittarius lagna the 7th house is Gemini, so Rahu in the 7th sits in Mercury's sign. Jupiter rules the lagna. Mercury rules the 7th and also the 10th, because Virgo is the 10th from Sagittarius. Rahu in Gemini is therefore disposited by a planet that owns both marriage and public work. The partnership can be tied to a career, a contract, or a person met through speech and trade. Gemini is a dual sign, so more than one serious bond is a theme to watch. It is not a promise of two marriages.

Rahu on the 7th unconventionalizes the spouse or the way the marriage happens: a different background, a foreign place, a sudden start, or a bond that does not match the family's picture. Because the dispositor is the 7th lord itself, Mercury's condition is the whole story's hinge. Mercury exalted in Virgo gives Rahu a precise, capable agent. Mercury debilitated in Pisces gives Rahu a confused one. Venus, the karaka of the wife in a man's chart, still has to be read. In a woman's chart Jupiter is the husband karaka, and here Jupiter is also the lagna lord, so the husband's topic and the native's body share a planet.

The pattern ripens in Rahu's 18-year mahadasha or in Mercury's 17-year mahadasha, and in their antardashas inside other periods. Before that, Rahu in Gemini can sit quietly. Navamsa has to confirm the 7th. If D9 puts the 7th lord in better condition than the birth chart, the lived marriage can be steadier than Rahu's reputation. If Saturn aspects the 7th, add delay. Do not add a breakup unless the 7th lord is also in the 6th, 8th, or 12th or the dasha is separative. Sagittarius rising with Rahu in the 7th is a specific map. It is not a curse on every Dhanu lagna.
