स्वाती
Svātī Nakṣatra
Swati's god is Vayu, the wind, and the Rigveda admits something about him that it admits about no one else: you can hear him, but nobody has ever seen him. The star sits alone in Libra under Rahu, and its oldest name was not Swati at all — the Taittiriya Brahmana calls it Nishtya, the outsider, the one that belongs somewhere else.
The Star at a Glance
What the Star Is
Swati sits entirely inside Libra, from 6°40′ to 20°. Most stars straddle two signs and have to be read twice; this one never does, which gives it something unusual — a single owner. Venus rules Libra, so Venus rules every degree a Swati person can possibly be born in, and for the first two and a half padas those degrees also fall inside Venus's mulatrikona, the narrow stretch where a planet stands at its strongest. But Venus does not rule the star itself. Rahu does. So the whole nakshatra is a planet with no body, living inside the sign of the planet that cares most how things look — and that quarrel runs through everything Swati does.
Go outside on a clear night and find it, because the sky explains this star faster than any table will. Almost every other nakshatra is a cluster — a V, a bow, a cart, three in a row. Swati is Arcturus: one star, well north of the path the planets travel, with nothing at all around it. The name is usually read as su-ati, the one that gets across on its own, and the old dictionaries also give it as the sword. Stand under it once and nobody has to explain independence to you.
Dr Aditya Togi, the astronomer on Dr Arjun Pai's panel, gives the way to find it. Follow the curved handle of the Big Dipper, the Saptarishi, and the arc leads to Arcturus; carry on and you reach Spica in Virgo. Arcturus lies about 31 degrees north of the ecliptic. Under Lahiri its longitude is Libra 0°22′, which falls inside Chitra's span, about six degrees before Swati's own span begins. It is an orange giant some 37 light years away, much larger and brighter than the Sun but cooler. It moves fast, and across the plane of the galaxy rather than with it, in a loose group called the Arcturus stream.
The Deity and the Older Name
Vayu is the wind, and the Rigveda treats him as someone you speak to rather than something you describe. He is called by name at the opening of the collection's second hymn, ahead of almost every other god. At the soma pressing his cup is filled first, and he takes the drink unmixed while the rest receive it cut with milk. Yet in the one hymn given over entirely to him, the poet admits outright that no one has ever seen him, and never tries to talk his way around it. A star whose god has no face is going to behave differently from a star whose god has one.
The Taittiriya Brahmana does not call this star Swati. It calls it Nishtya — the strange one, the foreigner, what stands outside the settlement. That is not a scribe slipping, because four other stars carry older names in the same list: Mrigashira is Invaka there, Pushya is Tishya, Jyeshtha is Indra's Rohini, and Mula is the Two Unfasteners. Meanwhile the Atharvaveda's Nakshatra Sukta, which walks through all twenty-seven and asks each to be kind, already says Swati, and asks this one to be pleasant. So the two names come out of two different layers of the tradition, and they are not describing the same thing. One of them is a request. The other is a warning.
The shakti usually attached to this star — pradhvamsa shakti, the power to scatter — is David Frawley's coinage, not a term the Brahmana supplies. The sutra's own pair is vratati above, the spreading of a creeper, and asiddhi below, non-accomplishment; no other star in that list is given a failure as its lower half. Frawley's published above and below for Swati read 'moving in various directions' and 'change of form', which is not the sutra's pair either. His scheme is repeated everywhere as though it were classical, so it is worth knowing where it came from. The star's desire, though, is in the Brahmana. Its offering for this star (3.1.4.13) says Vayu wished for kamachara, the power to go where he liked in all the worlds. That is the line teachers now quote as freedom to move as one wishes.
Dasha and the Solar Transit
A birth under Swati opens the Rahu mahadasha, and it runs eighteen years. Where in the star the Moon falls decides how much of that stretch is still ahead of the child: a Moon near the end of the nakshatra buys only a few months of it, a Moon at the start buys almost the whole thing. Rahu's period has a reputation for setting a person down somewhere they never planned to be, which is a fair description of what wind does to a seed. The Sun crosses Swati every year from about 24 October to 6 November, and that fortnight is when the star's own observances are kept.
