A Nakshatra is one of 27 lunar mansions that divide the sidereal zodiac into equal sections of 13°20′.
In Vedic astrology, or Jyotish, the sky is read through more than the 12 zodiac signs. The Nakshatras add a second layer: 27 equal segments around the same circle. Because the Moon moves quickly, its Nakshatra at birth is often treated as a more precise birth star than a broad Moon-sign label alone.
That birth placement is called the Janma Nakshatra, birth star, or Moon Nakshatra. Traditional interpretation connects it with emotional habit, instinctive response, resilience, and the tone of the mind under pressure. It is also where Vimshottari Dasha timing usually begins.
Each Nakshatra has a ruling planet, deity, symbol, Shakti, Gana, Yoni, and four naming sounds. These are part of the symbolic language of Jyotish: useful for reflection, not a scientific personality test. A fuller reading still looks at the whole chart, including the Ascendant, houses, and current planetary periods.
