Mula nakshatra: Ketu's star at the start of Sagittarius, the fears and what the texts actually say

Mula is the nineteenth nakshatra, the first 13°20' of Sagittarius, ruled by Ketu in the Vimshottari scheme. It begins exactly where Scorpio and Jyeshtha end, so its first minutes sit on one of the three Gandanta junctions BPHS names, and Mula births have long attracted worry in popular astrology. This page sets out what the books in this app's library say, including the line in Jyotisha-Siddhanta-Sara that answers the worry directly, and every number on it comes from running the app's engine.

Mula belongs to a 27-page series with one layout, so it can be read beside Jyeshtha before it and Purva Ashadha after it. The sign is described on the Sagittarius (Dhanu) page. The engine's method is on the methodology page and the books on the sources page.

Where Mula sits: the arc, the padas and the engine's facts

Mula is the 19th of the 27 nakshatras. Each nakshatra is 13°20' of the sidereal zodiac, 360 degrees divided by 27, and this app measures them from 0° Aries in the Lahiri (Chitrapaksha) frame. So Mula runs from Sagittarius 0°00' to Sagittarius 13°20', wholly inside Sagittarius. A planet is "in Mula" when its sidereal longitude falls inside that arc. When someone says "my nakshatra is Mula", they mean the Moon was there at birth: the Janma Nakshatra. The Moon moves about 13 degrees a day, so it crosses a nakshatra boundary inside most birth dates, and the nakshatra calculator reports the star at both ends of the birth date when no time is given. The difference between a rashi and a nakshatra is set out separately, as is why two apps can name two different stars for the same birth.

Mula lies wholly in Sagittarius, so a Moon there is a Sagittarius Moon, with Jupiter as sign lord and Ketu as star lord. Its start is the start of the sign, and Mula is therefore one of the three stars that begin a sign at the same instant as the previous star ends one; the others are Ashwini at Aries 0° and Magha at Leo 0°. Those three are also the three Ketu stars in the Vimshottari table, so every Ketu star begins at a sign boundary and every Gandanta junction is crossed into a Ketu period.

Inside the star the engine draws nine unequal sub-divisions, one for each Vimshottari lord, each as wide as that lord's share of the 120-year cycle, and the first belongs to Mula's own lord, Ketu. These sub-lords matter most for points that move fast through the sky, above all the Ascendant, which is why the sub-lord needs a birth time to the minute. The sub-lord calculator prints this same table for your own Moon:

What the classical texts say about Mula

Three books in this app's library speak about Mula directly. Jyotisha-Siddhanta-Sara (Rama R. Rao, 1994) gives every nakshatra a description in Ch. IV; the corpus copy is a scan with no text layer, so the pages cited below were read as images. Brihat Parashara Hora Shastra (BPHS) uses Mula as a counting point and a member of groups rather than describing it. Saravali names Mula in a Raja Yoga for the Sun, and Advanced Predictive Astrology repeats a modern rule about Rahu periods for Mula births. The readings are reported as the texts give them, with the same omissions the engine makes: the caste label each nakshatra carries in Jyotisha-Siddhanta-Sara is not repeated, nor are its predictions about appearance and marriage.

Jyotisha-Siddhanta-Sara, Ch. IV (pp. 87-115)

Entry 19, spelt Moola, describes the star as "in the form of the tail of a lion, composed of nine stars", with Nirrti as presiding deity. The people associated with it "are druggists, those who deal in medicinal plants and herbs, leaders of men and soldiers. They are rich and are associated with gardens, fruits, flowers, roots and seeds."

The prose reading: the person "will be haughty, rich, happy, not disposed to injure other men, of firm views and will live in luxury". The sloka and its translation are the most direct answer any book here gives to the fear around Mula: "The person born in Moola, although believed to bring misfortune to his family, is actually a benefactor to his family. He is prosperous and longlived." The engine's line, "often misjudged at first, but ultimately a steady benefactor to family, prosperous and long-lived", is a close paraphrase.

The same chapter also records the belief the sloka answers. On p. 88 it defines Abhukta Moola as "the last ghati (24 minutes) of Jyeshta and the first two ghatis (48 minutes) of Moola", and on pp. 114-115 its list of birth-star cautions divides Moola into twelve parts and also gives a reading by quarter, each naming a relative or matter affected. The app does not use or repeat predictions of harm to relatives, so the list is named, not reproduced. The book introduces that list with its own limit: "mere birth in these nakshatras cannot be the sole factor; the horoscope as a whole has to be assessed for any untoward happening. For example: if Guru is in the lagna or is aspecting it, it will cancel the ill-effects of the nakshatra."

Moola is one of the chapter's three neuter stars, with Mrigashira and Shathabhisha (p. 87), one of its four hot stars (p. 90), the Sristi member of its triad (p. 88), so no durithamsa caution applies, and one of the nine downward-looking Adhomukha stars (p. 88). On p. 87 it is one of the three gandantha stars that "commence with a rasi", with Aswini and Makha.

BPHS: Mula as a deity, a count and a group

BPHS gives Mula's deity twice, consistently: the nineteenth Saptavimshamsa lord in Ch. 6 Sl. 24-26 is Rakshasa, and Ch. 93 Sl. 1-2 says "the ruling deity of Mula is Rakshasa", opposing it to Jyeshtha's Indra as the reason the junction is feared. Jyotisha-Siddhanta-Sara names Nirrti.

Ch. 92 defines the junction. Sl. 3: the Nakshatra Gandanta includes "the last two Ghatikas of Jyeshtha and first two Ghatikas of Mula". Sl. 4 adds the Lagna Gandanta, "the last half Ghatika of Vrischik and first half Ghatika of Dhanu". Sl. 5: "the last 6 Ghatikas of Jyeshtha and first 8 Ghatikas of Mula are known, as Abhukta Mula." Ch. 92 Sl. 1 attaches a dire warning to births and undertakings in any Gandanta, and Chapters 92 to 94 then prescribe rites; this app prescribes no remedies and repeats neither the warning nor the Ch. 94 Sl. 11-13 marriage warning attached to Mula's first three quarters. The definitions are given here because they are what people are told to check.

Mula is also a counting point. Ch. 46 Sl. 37-39 sets out Dwisaptati-sama Dasha, "suitable in cases, where the Lord of Lagn is in Lagn, or in Yuvati", with the rule "Count from Mul to the Janm Nakshatr and divide the number by 8"; eight lords, nine years each. A Mula Moon counts 1 and starts with the Sun; the engine agrees. In the same chapter Shastihayani (Sl. 40-41) gives "Jyeshtha, Mul, P.Ashadha" to Śukr, and Kalachakra writes "Mul, Purvashadha and Uttarashadha in the Savya" (Sl. 56-58) and lists Mul among the ten stars whose padas are read "as the Padas of Ashvini".

For Ketu as a graha, see the Ketu page; for the Moon, the Moon in Vedic astrology page.

Saravali and Advanced Predictive Astrology

Saravali Ch. 35 Sl. 147: "The sun in Revati, Poorva Phalguni, Uttara Phalguni, or Moola identical with Ascendant will make one the head of a country extending to only hundred yojanas." For Mula that means a Sagittarius Ascendant with the Sun between 0° and 13°20' of Sagittarius, a sunrise-hour birth in that part of the solar year. It is a condition on the Sun's star, not the Moon's.

Advanced Predictive Astrology (Vol. II, pp. 124-125) lists working rules for dashas, several credited to a 1994 magazine, and includes: "Generally Rahu dasa is bad for people born with Asvini, Makha or Moola as Janma Nakshatra." Those are exactly the three Ketu stars. Run through the engine's sequence, a Mula native reaches Rahu after Ketu's balance and the full Venus, Sun, Moon and Mars periods, 43 years, so between 43 and 50 years after birth depending on the Ketu balance. The rule is a modern author's generalisation with no classical citation, and this page reports it as such. The book also places Moola in its Vata humour group (p. 225).

Where the sources disagree

The length of the junction differs: BPHS makes the Nakshatra Gandanta the first two ghatikas of Mula and Abhukta Mula the first eight; Jyotisha-Siddhanta-Sara makes Abhukta Moola the first two ghatis of Moola and its Anthara-ala a twelve-minute span across the boundary. At 24 minutes a ghati, the Mula side of the band is 48 minutes in Jyotisha-Siddhanta-Sara's Abhukta Moola (and in BPHS's narrower Gandanta) and about three hours twelve minutes in BPHS's Abhukta Mula. A reader told simply that a birth "was in Mula Gandanta" should ask which of these definitions was used.

Neither book converts its ghatikas into arc. The ghatika here measures how long the Moon has been in, or has left to run in, the star, which BPHS Ch. 46 Sl. 21-22 calls the Bhayat and Bhabhog when it explains the dasha balance. Because the Moon's speed varies, the same number of ghatikas covers more arc on a fast day than a slow one, so no fixed degree band reproduces any of these definitions exactly.

The deity is Rakshasa in BPHS and Nirrti in Jyotisha-Siddhanta-Sara. And Jyotisha-Siddhanta-Sara disagrees with itself in tone: its caution list treats parts of Moola as harmful to relatives, while its own sloka says the Mula-born person, though "believed to bring misfortune", is "actually a benefactor". The engine follows the sloka. Its Rakshasa gana and Dog yoni for Mula have no source in this library, as its header says.

The four padas of Mula

Each nakshatra splits into four padas of 3°20', and each pada is one navamsa, so the 108 padas of the zodiac walk through the twelve signs nine times. BPHS Ch. 46 Sl. 87-88 gives the rule as arithmetic: take the number of nakshatras already passed, divide by 3, multiply the remainder by 4, add the pada, and count that many signs from Aries. For Mula's first pada: 18 nakshatras have passed, 18 divided by 3 leaves 0, times 4 is 0, plus 1 is 1, and the 1st sign from Aries is Aries. The engine's computeNavamsa, which uses the sign-based rule from Jyotisha-Siddhanta-Sara Ch. II, returns Aries too. The Navamsa calculator shows the whole D9 chart, and the Navamsa article explains why it needs an accurate birth time.

Mula starts a new group of three stars, so its navamsas begin again at Aries: Aries, Taurus, Gemini, Cancer. None is vargottama. The first pada is the one every junction definition touches; at the Moon's average pace of about 13 degrees a day, BPHS's eight ghatikas of Abhukta Mula cover roughly the first degree and three-quarters of the sign, about half of the first pada, while Jyotisha-Siddhanta-Sara's two ghatis cover under half a degree.

The Kalachakra columns are the Ashvini pattern (BPHS Ch. 46 Sl. 60-64): Aries and Sagittarius as Deha and Jiva in the first pada, Capricorn and Gemini in the second, Taurus and Gemini in the third, Cancer and Pisces in the fourth. The app computes Kalachakra from them; for the second pada, which the text gives only as nine signs from Makar to Mithun, it reads Capricorn, Aquarius, Pisces, Scorpio, Libra, Virgo, Cancer, Leo, Gemini, the exact reverse of Mrigashira's third pada, totalling 85 years.

The sub-lord table makes the junction sharper still: Mula's first sub is Ketu's own, only 46.67 arc-minutes wide, followed by Venus's 133.33. A Moon in the first hour and a half of Mula is in Ketu's star and Ketu's sub at once.

Mula and the dasha sequence

BPHS Ch. 46 Sl. 12-14 finds the first Vimshottari dasha by counting from Krittika to the birth star and dividing by nine; the remainder picks a lord from the sequence Sun, Moon, Mars, Rahu, Jupiter, Saturn, Mercury, Ketu, Venus. Counting Krittika as 1, Mula is 17; 17 divided by 9 leaves 8, and that is Ketu. The engine reaches the same lord from its own table. Sl. 15 gives Ketu 7 years. A Moon in Mula therefore starts life in a Ketu Mahadasha, and Sl. 16 says how much of it remains: the part of the nakshatra the Moon has still to cross, as a share of the whole, times 7 years.

Run on a sample birth of 1 January 2000 with the Moon a quarter of the way into Mula, the engine leaves three quarters of the Ketu period, 5.25 years, and dates the next periods from there:

What a Ketu period is classically held to bring is on the Ketu Mahadasha page and the Ketu in Vedic astrology page; the Vimshottari dasha calculator gives your own dates, and the sub-periods article explains why those dates move when the birth time moves. Ketu's period is 7 years, shorter than every other lord's except the Sun's 6, so a Mula Moon always moves into the 20-year Venus period before the age of seven. In the sample above the Venus period begins in April 2005 and the Sun's in April 2025.

Ashtottari is the 108-year system BPHS Ch. 46 Sl. 17-20 offers as an alternative "when Rahu is not in Lagn, in any other Kendr, or Trikon to the Lord of the Lagn". It assigns stars in alternating runs of four and three from Ardra. Ashtottari has no Ketu period at all; Jyotisha-Siddhanta-Sara (p. 120) notes there are "only eight dasas in this system, Ketu being left out". Mula is the last of Mercury's run of three, Anuradha, Jyeshtha and Mula, so a Mula Moon starts in a Mercury period of 17 years, and by Sl. 21-22's one-third share for a benefic, two-thirds of it are taken as over at the very start of Mula. Jyotisha-Siddhanta-Sara Ch. V (p. 120) prints the same grouping as a table. The engine computes Ashtottari in full, so the app shows the Mercury balance and dates every Ashtottari period.

The engine does compute six other nakshatra-based systems from the same chapter, each with its own starting star and condition. For a Moon in Mula (sampled at the middle of the star) the alternate dashas calculator returns:

Dwisaptati-sama is the line that belongs to this star: it is counted from Mula, and for a Mula Moon it begins with the Sun, 9 years. Jyeshtha, a few minutes earlier, is the 27th and last in the same count. Every system in the table changes lord across the Jyeshtha-Mula boundary, which is one more reason the birth time matters at this junction.

Mula in compatibility and muhurat

Ashtakoot matching, the 36-point Guna Milan the match tool runs, reads four of its eight kootas from the two Moon nakshatras: Tara, Yoni, Gana and Nadi. The engine places Mula in the Rakshasa gana, the Aadi nadi and the Dog yoni. Its own header is candid that none of the classical books it works from contains the Ashtakoot rules, no nakshatra gana list and no koota point scale, so these tables are carried as they are rather than cited. One partial anchor exists: Advanced Predictive Astrology (p. 225) prints "Humour Producing Asterisms" in three groups of nine, Vata, Pitta and Kapha, and that grouping coincides star for star with the engine's Aadi, Madhya and Antya nadis. Mula sits in its Vata group. The book does not call this Nadi koota, and this page does not claim it does.

Two people with the Moon in Mula score 28 of 36 in the engine: full marks on seven kootas and 0 of 8 on Nadi, because the same star always means the same nadi. The other stars sharing Mula's Aadi nadi, and so also scoring 0 on Nadi against it, are Ashwini, Ardra, Punarvasu, Uttara Phalguni, Hasta, Jyeshtha, Shatabhisha, Purva Bhadrapada. On Yoni, Ardra shares the Dog and scores the full 4; the engine treats the Deer as the Dog's enemy, so Anuradha and Jyeshtha score 0; every other pairing scores 2.

Tara counts from each partner's star to the other's. The engine marks a count as unfavourable when it leaves 3, 5 or 7 after division by 9, and BPHS Ch. 44 Sl. 15-21 does name the 3rd, 5th and 7th stars from the birth star Vipat, Pratyak and Vadh, though in a chapter on longevity this page does not reproduce. Counted forward from Mula, the unfavourable stars are Krittika (12), Mrigashira (14), Punarvasu (16), Uttara Phalguni (21), Chitra (23), Vishakha (25), Uttara Ashadha (3), Dhanishta (5), Purva Bhadrapada (7). The score is 3 when both directions are clear, 1.5 when one is, and 0 when neither is. The compatibility feature shows every koota with its points, so a low total can be traced to the factor behind it.

For choosing a time, the muhurat feature and the muhurat calculator add 16 points to a window when the transiting Moon is in a star on the activity's list and take 6 away when it is not. Mula is on the Marriage list. Mula is on the engine's Marriage list and on no other; Jyotisha-Siddhanta-Sara classes Mula as hot and lists it among its cautionary birth stars, but neither point is tied to marriage timing in the pages read, so the engine's choice is reported, not judged. Jyotisha-Siddhanta-Sara (p. 89) also calls the 22nd star from one's birth star the vainasika nakshatra, "to be avoided for auspicious events"; for a Mula native that is Hasta. The engine does not apply that rule.

Checking Mula in your own chart

1. 1.Open the nakshatra calculator with your birth date and, if you have it, time and place. It returns the Moon's star, its pada and its lord. Without a time it also shows the star at 00:00 and 23:59, so you can see whether Mula held all day.
2. 2.Check the pada against the table above. The pada fixes the Moon's navamsa, which the Navamsa calculator shows in full.
3. 3.If your Moon is within a few arc-minutes of a sub-lord boundary, the sub-lord calculator prints the distance to the next one. An error of a few minutes in the birth time can move it.
4. 4.Open the Vimshottari dasha calculator to see the Ketu balance at birth and every period after it.
5. 5.Look at the whole chart in the birth chart calculator. A star describes the Moon's placement; the houses, the Ascendant and the other planets are read from the full chart.
6. 6.For matching, enter both birth details in the match tool; it computes both stars itself, so nothing has to be typed in by name.

For a Mula Moon, the first check is the distance from Sagittarius 0°. If it is under two degrees, the definitions above become relevant and the birth time decides which band, if any, applies; the unknown birth time article explains what can be known without it. The kundali feature shows the whole chart, which is what Jyotisha-Siddhanta-Sara says has to be assessed.

Common misreadings of Mula

• "A Mula birth brings misfortune to the family." Jyotisha-Siddhanta-Sara records that belief and then contradicts it in its own sloka: the Mula native "is actually a benefactor to his family".
• "All of Mula is Gandanta." BPHS confines the Nakshatra Gandanta to the first two ghatikas of Mula and Abhukta Mula to the first eight; the rest of the star lies outside every definition in these books.
• Gandanta is defined in ghatikas, units of time. Converting it to a fixed number of degrees assumes an average lunar speed; the real Moon is sometimes faster and sometimes slower.
• The app does not flag Gandanta or Abhukta Mula. Silence on the subject in a reading means the engine does not compute it, not that the birth is outside it.
• The Rahu-dasha rule in Advanced Predictive Astrology is a modern generalisation, credited to a magazine, covering all three Ketu stars. It is not a classical verdict, and it applies, if at all, decades into life.

Questions about Mula

Which sign is Mula nakshatra in?

Sagittarius, entirely: Sagittarius 0°00' to 13°20'. Its start is the start of the sign.

Who is the lord of Mula?

Ketu, with a Vimshottari period of 7 years. The deity is Rakshasa in BPHS and Nirrti in Jyotisha-Siddhanta-Sara. See the Ketu Mahadasha page for what the period is held to bring.

Is a Mula birth inauspicious?

The books disagree with themselves. Jyotisha-Siddhanta-Sara lists cautions for parts of Moola, but its sloka says the Mula native, though "believed to bring misfortune", is "actually a benefactor to his family", prosperous and long-lived, and it says birth star alone "cannot be the sole factor".

What is Abhukta Mula?

A band across the Jyeshtha-Mula boundary: the last 6 ghatikas of Jyeshtha and first 8 of Mula in BPHS Ch. 92 Sl. 5, or the last 1 and first 2 in Jyotisha-Siddhanta-Sara p. 88. The app computes neither.

What are the navamsas of Mula's padas?

Aries, Taurus, Gemini and Cancer. None is vargottama.

What gana, nadi and yoni does the app give Mula?

Rakshasa gana, Aadi nadi and the Dog yoni, shared with Ardra. The engine's header says no classical book in this library contains these tables.

Is Mula good for a wedding muhurat in the app?

Mula is on the engine's Marriage list, so a window with the Moon there gains 16 points on the nakshatra factor. The rest of the score, tithi, weekday, Rahu Kaal and the Moon's house, is computed separately; the muhurat feature shows each reason.

Does any classical text here praise a planet in Mula?

Saravali Ch. 35 Sl. 147 does, for the Sun: the Sun in Moola identical with the Ascendant, that is a Sagittarius Ascendant with the Sun in Mula, makes one "the head of a country extending to only hundred yojanas". It is one of several stars named in that verse.

Which dasha system counts from Mula?

Dwisaptati-sama (BPHS Ch. 46 Sl. 37-39), for charts whose Lagna lord is in the Lagna or the 7th. Eight lords of 9 years each; a Mula Moon starts with the Sun.
