Nakshatras: the 27 lunar mansions

Long before the twelve-sign zodiac became standard in India, sky-watchers tracked the Moon against a ring of star groups. Because the Moon takes about 27.3 days to return to the same position among the stars, it visits a different star group, roughly one each night. These became the nakshatras, often translated as lunar mansions: places where the Moon rests on its monthly journey.

How nakshatras are measured

The 360-degree sidereal zodiac is divided into 27 equal segments of 13 degrees and 20 minutes. The first, Ashwini, begins at 0 degrees sidereal Aries, and the last, Revati, ends at 30 degrees sidereal Pisces. Because 27 nakshatras and 12 signs do not line up evenly, some nakshatras span two signs. For example, Krittika begins in Aries and finishes in Taurus.

Each nakshatra is subdivided into four padas (quarters) of 3 degrees and 20 minutes. The 108 padas across the zodiac are a meaningful number in Indian tradition and are used for detailed interpretation and in the navamsa divisional chart.

The 27 nakshatras

• Aries to Cancer: Ashwini, Bharani, Krittika, Rohini, Mrigashira, Ardra, Punarvasu, Pushya, Ashlesha.
• Leo to Scorpio: Magha, Purva Phalguni, Uttara Phalguni, Hasta, Chitra, Swati, Vishakha, Anuradha, Jyeshtha.
• Sagittarius to Pisces: Mula, Purva Ashadha, Uttara Ashadha, Shravana, Dhanishta, Shatabhisha, Purva Bhadrapada, Uttara Bhadrapada, Revati.

Some traditions add a 28th, Abhijit, a narrow segment within Capricorn used mainly in electional astrology, but the standard system uses 27.

What each nakshatra includes

Every nakshatra carries a cluster of associations used in interpretation:

• A ruling planet (from the Vimshottari dasha sequence).
• A presiding deity from Vedic mythology, which colours its themes.
• A symbol, such as a horse’s head for Ashwini or a chariot for Rohini.
• A gana or temperament: deva (gentle), manushya (human) or rakshasa (intense).
• An animal symbol (yoni), used in compatibility matching.

For example, Ashwini is ruled by Ketu, linked to the twin healers known as the Ashwini Kumaras, and is associated with speed, beginnings and helping others. Rohini, ruled by the Moon, is associated with growth, beauty and fertility.

The planetary rulers

The rulers follow a repeating sequence of nine: Ketu, Venus, Sun, Moon, Mars, Rahu, Jupiter, Saturn and Mercury. The sequence runs three times through the 27 nakshatras. So Ashwini, Magha and Mula are all ruled by Ketu; Bharani, Purva Phalguni and Purva Ashadha by Venus; and so on.

Your birth nakshatra

The nakshatra occupied by your Moon at birth is called your janma nakshatra. In Vedic astrology it is one of the most personal parts of your chart, often considered as revealing as your Moon sign or more so. It is used to describe emotional temperament, to choose the first syllable of a baby’s name in some families, and in several compatibility methods.

Nakshatras and dashas

Your Moon’s nakshatra sets the starting point of your Vimshottari dasha. If your Moon was in a Venus-ruled nakshatra, your life begins in a Venus period. How far the Moon had travelled through the nakshatra determines how much of that first period was already used up at birth. From there, the periods follow the fixed sequence and fixed lengths, totalling 120 years.

Nakshatras in daily life

The Moon passes through each nakshatra in roughly a day, so the current nakshatra is a key element of the daily Panchang, the traditional Hindu almanac. It is consulted when choosing auspicious times for ceremonies, travel and new beginnings. Even if you do not follow these practices, noticing the daily nakshatra can be a thoughtful way to connect with the Moon’s rhythm.

Getting started

To find your birth nakshatra, you need a sidereal chart calculated with an ayanamsa such as Lahiri. Look up your Moon’s sidereal position and see which 13°20′ segment it falls in. Then read about its ruler, deity and symbol, and notice which themes resonate with your experience.
