Mula
The nineteenth of the 27 lunar mansions, the layer of the Vedic sky that Western astrology does not have. Mula is the nakshatra of the root: its deity is Nirriti, who undoes what is finished with, its symbol is a bundle of roots pulled from the ground, and its stars are the sting of the Scorpion, which point at the centre of the galaxy. The name means the root.
What the tradition says
Mula's image is of going to the bottom of things and pulling: the root that is dug up, whether to heal with it or to clear the ground. The classical texts read it as depth of enquiry, a comfort with dismantling what most people would leave standing, and a philosophical fearlessness about endings. Ketu rules the mansion, which gives the digging its strangeness; what is found at the root is not always what was expected.
The honest shadow in the sources is destruction that outruns its purpose: a habit of uprooting what was fine where it was, a bluntness that wounds, and a loss of the ground under one's own feet. The texts treat Mula with respect and with caution, and say its people must learn when the digging is done.
A Mula Moon
A Mula Moon describes a mind that goes to the root: feelings examined to their source, an intolerance of surfaces, and an unsettledness that comes from having questioned the foundations. Anyone born with the Moon here begins life in a Ketu period, and the sequence of their planetary seasons runs from there.
The four padas
All four of Mula's padas fall in sidereal Sagittarius. The navamsa runs Aries, Taurus, Gemini, Cancer across them; the tradition reads the first as the most forceful in its uprooting, and the fourth, in Cancer, as the one where the root is dug up in order to be replanted.
In degrees: pada 1 from 0° Sagittarius to 3°20′ Sagittarius with a Aries navamsa, pada 2 from 3°20′ Sagittarius to 6°40′ Sagittarius with a Taurus navamsa, pada 3 from 6°40′ Sagittarius to 10° Sagittarius with a Gemini navamsa and pada 4 from 10° Sagittarius to 13°20′ Sagittarius with a Cancer navamsa.
Why your Western chart never mentions this
There is no Western equivalent of Mula.
Western astrology divides the sky into twelve signs and stops. The Vedic system lays 27 mansions of 13°20′ over its twelve signs, a finer grain with its own deities, symbols and timing system. There is no Western equivalent of Mula, which is why a person can know their "big three" thoroughly and still meet something new the first time their Vedic chart is calculated. It is not that one system is finer-grained and therefore truer; they are answering different questions, and we show you both so you can see where they agree, and where they argue.
The Sun passes through Mula from about 16 December to 29 December each year, which Western astrology calls Sagittarius and Capricorn. A Moon can be here on any day of the year, since the Moon crosses a mansion in about a day, and it is the Moon the tradition reads first.

Questions people ask
Is Mula a good nakshatra?
The tradition does not rank the mansions as good and bad; each carries a capacity and a cost, and Mula's are the gift of going to the root and the tax of what gets pulled up with it. Readings that call nakshatras lucky or unlucky are selling something.
What if my Moon is at the edge of Mula?
Then your pada matters more than usual, and your birth time matters more than usual, since the Moon moves about 13 degrees a day and crosses from Jyeshtha into Mula and on into Purva Ashadha within two. The calculator shows your exact degree and flags it when a placement sits near an edge.
I am a Sagittarius in Western astrology. Is Mula the same thing?
No. Your Western sign comes from the tropical zodiac; Mula is a sidereal mansion that lies inside sidereal Sagittarius. You can be a Western Sagittarius with no Mula placements at all, and a Western Capricorn with a Mula Moon. The free chart shows your actual pair.
