The lunar mansions
A nakshatra is one of twenty-seven equal segments of the zodiac, each about thirteen degrees wide — the 'lunar mansion' the Moon occupies on a given night. The system is far older than the twelve sun-signs in Indian usage, and the nakshatra of your birth Moon is central to traditional naming, matching, and muhurta.
Long before the twelve zodiac signs entered Indian astronomy, the sky was divided into twenty-seven nakshatras — 'lunar mansions' — each a thirteen-degrees-twenty-minutes slice of the ecliptic. The name means roughly 'that which does not decay', and the scheme appears in some of the oldest Indian texts. Each night the Moon, moving about thirteen degrees a day, rests in roughly one nakshatra, which is how the system maps the lunar journey.
Every nakshatra has a presiding deity, a ruling planet, a symbol, and a temperament — Rohini the red one, Ashwini the swift healers, Magha the throne of ancestors, and so on. The nakshatra in which the Moon sits at birth, the janma nakshatra, is one of the most personal coordinates in a chart and traditionally guides the choice of a child's name and the timing of ceremonies.
The nakshatras also drive the compatibility scoring used in traditional marriage matching and the selection of an auspicious moment, or muhurta, for important acts. Many of the day-to-day judgements in the almanac that look like the zodiac at first glance are in fact nakshatra-based — which is why two systems coexist comfortably in Indian practice.
Your janma nakshatra is a computed fact, read from the Moon's exact position at your moment of birth. It is one of the first things a Vedic reading establishes, and a good place to begin understanding why Indian astrology leans so heavily on the Moon rather than the Sun.
There is a way to act on what you have just read — gently, and on your own terms.
