How to read a navamsa chart: calculation, vargottama and the D9 in practice

The navamsa is the divisional chart clients ask about most, usually for marriage. Here is how it is built, what Parashara and Mantreswara use it for, and how to use it without overreading it.

Short answer

To read a navamsa chart, first build it correctly. Each sign splits into nine parts of 3 degrees 20 minutes, counted from the sign itself if movable, from its 9th if fixed and from its 5th if dual ¹. Parashara reads spouse matters and the strength of planets in the D9 ². Then look for vargottama planets, which hold the same sign in both charts, since their periods read as favourable ^3,4. Read the birth chart first and use the D9 to confirm it. On Kismo, the application reading is one chat of about 10 minutes, read in full by a person, so one clear D9 point shows depth.

One navamsa: 3 degrees 20 minutes, a ninth of a sign: 108 in the zodiac (calculated)
Counting rule: Movable sign from itself, fixed from its 9th, dual from its 5th ¹
What Parashara reads in it: Matters of the spouse, and the strength or weakness of planets ²
Vargottama: A planet whose navamsa sign is the same as its birth-chart sign ³
Vargottama degrees: 0 to 3°20' in movable signs, 13°20' to 16°40' in fixed, 26°40' to 30° in dual (calculated)
Birth-time sensitivity: The lagna changes navamsa about every 13 minutes on average (calculated)

What it is

What is the navamsa chart, and what did Parashara use it for?

The navamsa, or D9, is the divisional chart made by splitting every sign into nine equal parts. It is one of the sixteen divisional charts Parashara lists ¹.

Parashara gives it two jobs: matters of the spouse are judged from the navamsa, and the strength and weakness of planets are seen in it ². Mantreswara records that some astrologers give a navamsa the same weight as the sign and house itself ³.

Each navamsa is 3 degrees 20 minutes, which is also the length of one nakshatra pada. So the 108 navamsas of the zodiac match the 108 padas one for one.

Calculation

How do you calculate a planet's navamsa?

A planet's navamsa is found by counting its ninth-part within the sign from a fixed starting sign. Parashara starts from the sign itself for movable signs, from its 9th for fixed signs and from its 5th for dual signs ¹.

Birth sign	First navamsa starts in
Aries, Leo, Sagittarius	Aries ³
Taurus, Virgo, Capricorn	Capricorn ³
Gemini, Libra, Aquarius	Libra ³
Cancer, Scorpio, Pisces	Cancer ³

Mantreswara's shortcut in this table gives the same answer as Parashara's rule ^1,3. A worked example: the Moon at 17 degrees Taurus is in the 6th ninth of the sign. Counting six signs from Capricorn gives a Gemini navamsa.

Vargottama

What is vargottama, and why does it matter?

Vargottama is the name for a navamsa that bears the same sign as the planet's birth-chart sign ³. By the counting rule this happens in the first ninth of movable signs, the middle ninth of fixed signs and the last ninth of dual signs.

Mantreswara says the dasha of a planet in vargottama gives favourable results, and mixed ones if that planet is also combust or debilitated ⁴. Parashara even uses it to choose a dasha system: a vargottama lagna calls for the 100-year dasha ⁵.

Parashara ties two more dasha systems to the navamsa. Birth in a Venus navamsa calls for Dvadashottari, and a Cancer lagna in the Sun's navamsa for Panchottari ⁵.

Reading order

In what order should you read the D9?

Check the birth time. The lagna moves through a sign in about two hours on average, so it changes navamsa every 13 minutes or so.
Read the birth chart's promise first; see how to read a kundli.
Mark every vargottama planet.
Note planets that gain or lose dignity in the D9, since Parashara reads strength there ².
Find the D9 lagna and its lord; Mantreswara says a strong lord of the rising navamsa brings happiness and comfort ³.
Only then answer the client's question, starting from the birth-chart house it belongs to.

Marriage questions

How do you use the D9 in a marriage question?

In a marriage question the D9 confirms or qualifies what the birth chart's 7th house already shows. Parashara assigns spouse matters to the navamsa ², so read the 7th house and its lord in the birth chart first; see how to read the 7th house.

Then check how the 7th lord and Venus fare in the D9: stronger, weaker or vargottama. Timing comes from the dasha, not from the D9; see marriage timing and kundli matching.

In the chat

How do you explain the navamsa to a client in chat?

Most clients have never heard of the navamsa, so describe it as a closer look at the same chart. One sentence of method, then the finding.

Client (example)
Someone told me my D9 is bad, so my marriage will fail. Is that true?
Astrologer (example)
No chart can say that. The D9 is a closer look at your birth chart. Your Venus keeps the same sign in both charts, which the old texts count as a strength.
Client (example)
Then why do I fight with my husband?
Astrologer (example)
Your 7th house shows two strong personalities. Shall we look at the period you are in now and what it asks of both of you?

This exchange is a made-up example, not a real client.

Never tell a client a marriage will fail, a spouse will cheat or a partner will die. Nothing about a pregnancy's outcome or an unborn child's gender, and no legal advice on divorce: that belongs with a lawyer.

On Kismo

How does Kismo's application reading reward this kind of depth?

Kismo's application includes one reading in chat with a client, about 10 minutes long, in Hinglish or English. For astrologers, the client's card shows the birth details and chart, so a precise D9 point is possible in that time.

Answers must be typed by you; pasted answers are sent back, and there is one try.
A person reads every reading in full, and the decision comes by email within 2 days.
Practices, languages and years of experience cannot be changed after you submit.
The app's short course for astrologers opens with an episode called People pay for depth.

Questions

What do astrologers ask about this?

Is the navamsa more important than the birth chart?

No, read the birth chart first. Parashara uses the navamsa for spouse matters and for planetary strength ², and Mantreswara notes that only some astrologers give it the same weight as the sign itself ³. Use it to confirm or qualify what the birth chart promises.

What does vargottama mean in a navamsa chart?

Vargottama means a planet's navamsa sign is the same as its birth-chart sign ³. It happens in the first ninth of movable signs, the middle ninth of fixed signs and the last ninth of dual signs. Mantreswara reads such a planet's dasha as favourable ⁴.

How exact does the birth time need to be for the D9?

Quite exact for the lagna. A sign rises in about two hours on average, so the navamsa lagna changes roughly every 13 minutes. In the Kismo application reading, work from the birth time on the client's card and say how sure the D9 lagna is.

Can the navamsa show when a client will marry?

Not on its own. Parashara assigns spouse matters to the navamsa ², but timing comes from the dasha and transits. Read the D9 for the quality of the promise, then the running periods for the window.

Should I mention the D9 in my Kismo application reading?

Only if it answers the client's question. Kismo's reviewers read the whole chat, and one clear, typed point tied to the question shows more skill than a list of charts.

Why does my software show a different D9 from the client's app?

Usually a different birth time, place or ayanamsa. A small shift moves the navamsa lagna, and a planet near a ninth-part boundary can change its navamsa. Check those three settings first.
