Jyeṣṭhā Nakṣatra

The Star of the Eldest

The Name

Every other nakshatra is named for what it looks like or what lives there — a bed, a bull's head, an anthill, a serpent's coil. Jyeshtha is named for a status. The word is the superlative of jya, 'to overpower,' and it carries both senses at once: the eldest, and the one who prevails. In ordinary Sanskrit it is what an older sibling is called. In the Rigveda it is what Indra is called.

The name also lives on in the calendar. Dr Aditya Togi, the astronomer on Dr Arjun Pai's panel, points out that the lunar months are named for the star near which their full Moon falls. The month Jyeshtha, in early summer, is the month whose full Moon falls near this star.

The star earns the name physically as well. Antares is a red supergiant so large that, placed at the centre of our solar system, its surface would swallow the orbit of Mars. It sits almost exactly on the ecliptic — the Moon passes across it, and can occult it outright — which is why every ancient sky-watching culture fixed on it. The Greeks named it Antares, 'rival of Ares,' for its unmistakable red. The Persians counted it one of the four Royal Stars that guarded the quarters of heaven.

Two astronomical details came up on Dr Pai's panel, and both check out. Santhip gives the sidereal positions as Aldebaran at Taurus 15°56′ and Antares at Scorpio 15°55′. Computed under Lahiri they are Taurus 15°56′ and Scorpio 15°54′, so the two red stars face each other almost to the minute. That also places Antares about 46′ before Jyeshtha's span begins, in the last pada of Anuradha. Santhip also notes that Antares has a small companion, Antares B. Johann Tobias Burg first reported it during a lunar occultation in April 1819. The Scottish astronomer James William Grant then saw it from India on 23 July 1844. The Sun passes Antares each year around 2 December, about a day before it enters Jyeshtha.

The Two Red Stars

The oldest Sanskrit list of the nakshatras does not call this star Jyeshtha at all. In the Nakshatra Sutras of the Taittiriya Brahmana it is rohini — 'the red, growing one' — and it is Indra's Rohini, to distinguish it from Prajapati's Rohini, the star we still call by that name today. The Vedic sky therefore holds two Rohinis, and they are not a duplication or a scribal slip. They are a matched pair: Aldebaran and Antares, both red giants of the first magnitude, standing almost exactly opposite one another on the ecliptic, so that one rises as the other sets. The tradition saw two red eyes at either end of the sky and named them for the same colour.

What separates them is what each does. The Taittiriya Brahmana gives every nakshatra a two-part formula, one force from above and one from below. Prajapati's Rohini receives water from above and plants from below — the whole apparatus of nourishment. Indra's Rohini receives crushing from above and crushing in return from below. The same redness; opposite work. One red star feeds the world and the other fights it. Read together, they are the clearest single statement the Vedic literature makes about what this nakshatra is for.

The Last Star of the Water

Jyeshtha closes Scorpio, and it closes it exactly — its final degree is the sign's final degree. This makes its fourth pada gandanta, the 'knot' where a water sign gives way to a fire sign and the thread of one elemental order is cut before the next begins. There are only three such junctions in the zodiac, and this one, running from the end of Jyeshtha into the beginning of Mula, is the most severe of them in classical reckoning. It is why a birth in Jyeshtha's last degrees is treated with a caution that a birth in its first degrees is not, and why the two facts most often confused about this nakshatra — that it is dangerous, and that it is fearsome — need to be kept apart. The gandanta is a real technical condition affecting a specific arc. The fearsomeness is a temperament, and it belongs to the whole star.

Daśā and the Mercury Cycle

Jyeshtha's dasha lord is Mercury, whose Vimshottari period runs seventeen years — and Mercury sitting on Antares is one of the sharper ironies in the system. Mercury is the youngest of the grahas, the kumara, the one classical iconography draws as a boy. He rules the star called the Eldest. A Jyeshtha native lives inside this contradiction: the intellect is quick, verbal, analytical and young, while the position it is asked to hold is senior, weighty and exposed. The Mercury mahadasha tends to be when the demand arrives — responsibility, rank, a title, the eldest's job — and whether it is carried or merely endured depends almost entirely on whether the person has done the work the previous dashas offered them.
