Shatabhisha Nakshatra: The Classical Character of the Lunar Mansion
Shatabhisha among the 27 lunar mansions
Shatabhisha is one of the 27 nakshatras — the 13°20′ lunar mansions that form the oldest layer of the tradition. Like each of its siblings, Shatabhisha is described by a presiding deity, a symbol, and a ruling planet — Rahu, whose Vimśottarī daśā a Shatabhisha Moon opens. The Moon's mansion at birth is read as an especially telling marker of temperament and mind; everything on this page is doctrine about Shatabhisha as a placement, never a forecast about a person.
Shatabhisha's daśā arithmetic, and its lord-siblings
A Moon in Shatabhisha opens the 120-year Vimśottarī cycle in Rahu's mahādaśā — 18 years long in full. In full, because the opening period is almost never whole: how far through Shatabhisha's arc the Moon stood at birth decides the balance of Rahu's daśā actually remaining — a precise, computable number, not a vibe. Rahu also rules Ardra and Swati — mansions sharing Shatabhisha's daśā lord while keeping their own deity, symbol, and temperament, which is exactly why lord alone never settles a reading.
What the tradition associates with Shatabhisha
The tradition places Shatabhisha under the presiding deity Varuṇa (the cosmic waters and cosmic law), with the symbol of an empty circle / a hundred healers. Its Vimśottarī daśā lord is Rahu, so the tradition treats Rahu's significations as colouring the mind and life-themes this nakshatra is associated with. Classically it is a Rākṣasa (fierce) nakshatra with the Horse as its yoni (the animal symbol used in classical compatibility matching). Taken together, the texts associate Shatabhisha with healing, mystery, and a solitary, investigative independence. These are tendencies the tradition describes, not fixed traits, and never a prediction.
Shatabhisha on the zodiac: span and padas
Shatabhisha's geometry first, because it is checkable: every mansion is a 13°20′ arc, and Shatabhisha sits entirely inside Aquarius. Shatabhisha divides, like each of the 27, into four padas of 3°20′, and each pada maps to a navāṁśa (D9) sign in the standard 108-fold cycle — for Shatabhisha: pada 1 → Sagittarius, pada 2 → Capricorn, pada 3 → Aquarius, pada 4 → Pisces. The pada is why two people sharing a Shatabhisha Moon can still differ classically: their navāṁśa positions need not match.
How to read this
Treat Shatabhisha as one classical layer, not a verdict. The tradition reads a nakshatra together with which graha actually stands in it, the sign and house it falls in for you, and the running Vimśottarī daśā — Rahu's period, for a Shatabhisha Moon, is where the cycle opens. A generic mansion description can only go so far; your own chart, with your real Moon-nakshatra and pada, says far more.

Common questions
- What does it mean that my Moon is in Shatabhisha?
- Classically, the Moon's nakshatra is read as a marker of temperament and mind — for Shatabhisha, the tradition's associations run toward healing, mystery, and a solitary, investigative independence. It also sets your Vimśottarī daśā clock: a Shatabhisha Moon begins the cycle in Rahu's daśā. Both are tendencies and timing structure, not a fixed portrait.
- Does Shatabhisha matter for anything besides the Moon?
- Yes — every graha stands in some mansion, and Shatabhisha colours any planet placed within its arc (the Moon's position is simply the most weighted). Shatabhisha's gaṇa (Rakshasa) and yoni (Horse) also enter guṇa-milāna matching whenever a partner's Moon falls here. Which of your planets, if any, occupy Shatabhisha is a fact of your chart.
