Mrigashira nakshatra: the deer's head

Mrigashira, "the deer's head", is the fifth nakshatra: it lies in the small stars of Orion's head and spans the end of Vrishabha and the start of Mithuna. Soma, the Moon and its nectar, is its deity, a deer's head its emblem, and Mangala its Vimshottari lord.

Meaning

The name means "the deer's head", and the stars are the faint group at the head of Orion, lambda and phi Orionis.

Modern readings take the deer in the forest as their image: curious, gentle and alert, always looking for something a little further on, sensitive to every sound. In the tradition's reading the search matters more than any one thing found. Our chart's text puts it the same way, as a restless curiosity that settles when the search itself is enough.

Mangala, Mars, is its lord in the Vimshottari order, with seven years. Mrigashira straddles two rashis: its first two padas lie in Vrishabha and its last two in Mithuna, so its reading in a chart is often coloured by the rashi it falls in.

Deity and emblem

Soma, the deified Moon and the nectar pressed for the rites, is Mrigashira's deity in the Taittiriya Samhita (as Mrigashirsha) and in today's books.

The emblem is a deer's head; the medieval lists give an antelope's head, the same idea with another animal.

In the chart

Mrigashira runs from 23°20′ Vrishabha to 6°40′ Mithuna of the sidereal zodiac, the fifth of 27 equal parts of 13°20′. It lies across two rashis: its first two padas in Vrishabha and the rest in Mithuna. Its four padas of 3°20′ fall in the navamsas of Simha, Kanya, Tula and Vrishchika, so a graha in its first pada stands in Simha in the D9.

Its Vimshottari lord is Mangala, whose period is seven years. When the Moon stands here at birth, the reckoning opens in Mangala's period and counts only the part still to run, in proportion to the part of Mrigashira the Moon has yet to cross. In 2026 the same stretch of sky is about 17°33′ Gemini to 0°53′ Cancer 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): Soma, as today; the Taittiriya list begins with Krittika.
The medieval lists (Burgess and Whitney, 1860): The figure of the asterism: an antelope's head, after the Ratnamala and the Muhurta Chintamani.
Modern Jyotisha: Curiosity, gentleness, alertness, a search that always goes a little further; its symbol: deer's head.
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: "Mrigashira, ruled by Mangala, carries the gentle curiosity of a deer searching through the forest. Its energy is inquisitive, sensitive and restless, and discovering that the search itself can be fulfilling helps settle a constant longing for more." Our words.

Claims about it

Mrigashira's deity and symbol are one fixed set handed down from the Vedas.
disputed

What the record shows: The deity, Soma, 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, deer's head, is the modern tradition's; here it matches the figure of the medieval lists, an antelope's head.
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.
