• the 1st house by its 7th aspect: it brings thought and talk into self and body; that house is Sagittarius, ruled by Jupiter, so optimism is what it touches.

Which nakshatra: Gemini in parts

Within Gemini, the exact degree puts Mercury in one of these nakshatras, each with a lord that has its own role in a Sagittarius chart:

• 0°–6°40′ Gemini: Mrigashira, ruled by Mars, lord of the 5th and 12th here, which brings children, intelligence and romance into it; for work it points to research, travel, writing, textiles and searching professions.

• 6°40′–20° Gemini: Ardra, under Rahu, adding a hungry undertone; in love it feels storms of emotion and wants honest, raw connection.

• 20°–30° Gemini: Punarvasu, a Jupiter nakshatra, linking the placement with the 1st and 4th (self and body; home, mother and property); in love it returns to love, forgives and rebuilds relationships.

Love and marriage

In the 7th Mercury brings a youthful, articulate or business-minded partner; communication is the marriage's strength, and keeping promises in writing and in spirit keeps trust. Whatever the house, Mercury in relationships is drawn to wit and good conversation, and keeps a relationship alive through shared curiosity. Because it rules the 7th, marriage in this chart is lived out through marriage and partnership, and the partner often shows something of Gemini: curiosity, wit and a need for variety. Mercury owns the 7th for this ascendant, so where it sits is where marriage is lived out; the Navamsa (D9) confirms it.

Career and money

As 10th lord it is the career planet for Sagittarius rising, so the work itself tends to involve marriage and partnership. Gemini is air: ideas, communication, networks and trade suit it. Mercury rules only angles here, so it carries kendradhipati dosha, the classical caution that a natural benefic owning angles loses some of its gentleness; much depends on its sign and company. As for wealth, income comes through skill, trade and more than one source.

Family and home

Domestically, a lively, talkative household with books, study and younger relatives. The 4th house here is Pisces, ruled by Jupiter, which says more about home than Mercury does.

When it gives results: the Mercury dasha
