Mula
The root star: digs to the bottom of things, including things better left buried.
What Mula means
Mula means root, and it is investigative to the point of upheaval. It sits at the galactic centre and it has the temperament to match: it will pull a thing up entirely to see what it was growing from. Great for research, medicine, philosophy and healing. Hard on stability.
The work: Dig for the truth. Replant something afterwards.
Your birth star is where the Moon was
A nakshatra is not a sign. The sidereal zodiac is divided two ways at once: into twelve signs of 30 degrees, and into twenty-seven nakshatras of 13 degrees 20 minutes. Your birth star is the nakshatra the Moon occupied at the moment you were born, and jyotish weighs it as heavily as the sign, sometimes more.
Mula occupies 0°00' Sagittarius to 13°20' Sagittarius. Because a nakshatra is narrower than a sign, finding yours needs an exact birth time: the Moon crosses one about every day, so a few hours can move you into the next.
With the Moon in Mula
A Moon here goes to the bottom of a feeling and pulls the root up to look at it. That is genuinely healing and genuinely destabilising, sometimes in the same week.
The four padas of Mula
Every nakshatra divides again into four quarters called padas, of 3°20' each. The pada your Moon falls in refines the reading further and decides its position in the navamsa, the divisional chart jyotish uses for marriage and for the real strength of a planet.
Why Mula being ruled by Ketu matters
Mula is ruled by Ketu. That is not decoration: the nakshatra your Moon sits in decides which planetary period, or dasha, your life opens with. The twenty-seven run three times through the same nine lords, so Ketu rules Mula and two others, and the Vimshottari system uses that to time when things happen rather than only what they mean.
The gana is Rakshasa, which is demonic in the old sense, meaning fierce rather than evil: intense, protective, hard to move. Classical matchmaking still uses it when comparing two charts.
Where the other mirrors say something similar
Six Mirrors reads a birth through six traditions at once, and shows you where they independently agree. The birth star is the finest grain any of them offers, which makes it one of the most useful things to check a convergence against.
Sidereal positions use the Lahiri ayanamsa. Degree spans and ruling planets are derived from the nakshatra's index rather than transcribed, and checked against the engine's own calculation.
