Jyotisha Chart (Sidereal) · Nakshatra 15 of 27

Swati, Arcturus and the wind

Swati, usually glossed "the independent one", is Arcturus, far north of the ecliptic, and lies wholly in Tula. Vayu, the wind, is its deity in every list; its modern emblem is a young shoot bending in the breeze, and Rahu is its lord.

Meaning

Swati is the star Arcturus, and the name is usually glossed "the independent one". Arcturus lies far north of the Sun's path, so here more than anywhere the nakshatra's name points at a star well away from the band it labels.

Modern readings follow the wind: independence that bends without breaking, grace, a love of freedom and a need for roots. Our chart's text uses the same image of a young shoot swaying, and says that inner roots let such suppleness stand firm when the wind changes.

Rahu is its lord in the Vimshottari order, with eighteen years; it is the middle of Rahu's three nakshatras, between Ardra and Shatabhisha.

Deity and emblem

Vayu, the wind, is Swati's deity in the Taittiriya Samhita and today.

The modern emblem is a young shoot swaying in the wind. The medieval lists give something else entirely, a coral bead, a gem or a pearl, so the shoot is the modern tradition's image.

In the chart

Swati runs from 6°40′ Tula to 20°00′ Tula of the sidereal zodiac, the fifteenth of 27 equal parts of 13°20′. It lies wholly within Tula (Libra). Its four padas of 3°20′ fall in the navamsas of Dhanu, Makara, Kumbha and Meena, so a graha in its first pada stands in Dhanu in the D9.

Its Vimshottari lord is Rahu, whose period is eighteen years. When the Moon stands here at birth, the reckoning opens in Rahu's period and counts only the part still to run, in proportion to the part of Swati the Moon has yet to cross. In 2026 the same stretch of sky is about 0°53′ Scorpio to 14°13′ Scorpio in the tropical zodiac, by the Lahiri measure; another ayanamsa moves the edges, and a Moon or lagna within a few minutes of arc of an edge can fall in the neighbouring nakshatra in another tool.

How the schools read it

The Vedic lists (Taittiriya Samhita iv.4.10, Keith 1914)
Vayu, as today; the Taittiriya list begins with Krittika.
The medieval lists (Burgess and Whitney, 1860)
The figure of the asterism: a coral bead, gem or pearl, after the Ratnamala and the Muhurta Chintamani.
Modern Jyotisha
Adaptable independence: supple, gracious, freedom-loving, bending without breaking; its symbol: young shoot swaying in the wind.
The 28-nakshatra scheme
Abhijit, in the stars of Lyra, stands between Uttara Ashadha and Shravana in the older lists; the equal division into 27 leaves it out.
Western sidereal (Fagan-Bradley)
The same 27 divisions, about 0°53′ further on than Lahiri's; Western siderealists rarely use them.
EsoTerrier
Our chart's text for a Moon here: "Ruled by Rahu, Swati is pictured as a young shoot bending in the breeze, independent yet supple. Its energy is adaptable, gracious and freedom-loving, and developing inner roots helps that flexibility stand firm when the winds change." Our words.

Claims about it

  • Swati's deity and symbol are one fixed set handed down from the Vedas.

    disputed

    What the record shows: The deity, Vayu, is the same in the Taittiriya Samhita (iv.4.10) and today, but five other nakshatras have different deities in different Vedic lists. The symbol, young shoot swaying in the wind, is the modern tradition's and has no dated source we found; the medieval lists give a coral bead, gem or pearl.

  • The nakshatra is a constellation, 13°20′ wide.

    false

    What the record shows: The nakshatras began as star groups of unequal size, 28 in the Atharvaveda with Abhijit. The equal division into 27 parts of 13°20′ is a later convention; the name points at stars, the division is arithmetic.
