Which nakshatra: Leo in parts

The degree matters too: Leo is divided between these nakshatras, whose lords bring their Sagittarius-rising houses into play:

• 0°–13°20′ Leo: Magha, ruled by Ketu, which adds detachment and intuition; for work it points to government, heritage, history, leadership and family business.

• 13°20′–26°40′ Leo: Purva Phalguni, a Venus nakshatra, linking the placement with the 6th and 11th (work, health and rivals; gains and networks); for work it points to entertainment, arts, hospitality, beauty and luxury.

• 26°40′–30° Leo: Uttara Phalguni, ruled by the Sun, lord of the 9th here, which brings fortune, faith and teachers into it; in love it seeks a committed, contractual partnership and keeps its word.

In the 9th Mercury favours a partner met through study, travel or teaching; shared ideas and the freedom to question keep the bond fresh.

Because it rules the 7th, marriage in this chart is lived out through fortune, faith and teachers, and the partner often shows something of Leo: warmth, pride and a desire to be seen. Because Mercury rules the 7th here, its placement is the primary marriage signature, read with Venus and the Navamsa.

Career and money

Mercury in the 9th favours publishing, higher education, law and teaching; learning brings fortune. Typical careers for Mercury, more widely: commerce, writing, analysis, software, accounting and anything that runs on information. Being the 10th lord, it ties profession and reputation to fortune, faith and teachers. Fiery Leo favours work where it can lead. Being lord of the 7th (an angle) placed in the 9th (a trine), Mercury links action with merit. Classical raja yoga needs an angle lord and a trine lord to join, aspect each other or exchange signs, so any planet with Mercury here is worth checking. 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, several streams of income and good bookkeeping are the natural pattern.

Family and home

On the family side, conversation, study and younger relatives keep the household busy. For the home itself, Jupiter (lord of Pisces, the 4th) is the main witness.
