The Navamsa (D9) divides each sign into nine parts of 3°20', the same span as a nakshatra pada. Astrologers read it beside the rashi chart (D1) to test how well a planet can deliver its D1 promise, to judge marriage and the spouse, and to spot vargottama planets, which occupy the same sign in D1 and D9 and are generally considered strengthened.
Why D9 sits next to D1
A planet exalted in D1 can still struggle to deliver if it falls debilitated in the Navamsha. A modest D1 placement can work better than expected when the D9 is strong. That is why most Parashari astrologers never read a significant planet in D1 without a glance at D9, and why a consultation desk should show them side by side.
How the Navamsha is calculated
Each sign of 30° is divided into nine navamshas of 3°20'. The first navamsha of a sign begins from:
- Movable (chara) signs (Mesha, Karka, Tula, Makara): the same sign.
- Fixed (sthira) signs (Vrishabha, Simha, Vrishchika, Kumbha): the 9th sign from it.
- Dual (dvisvabhava) signs (Mithuna, Kanya, Dhanu, Meena): the 5th sign from it.
An equivalent rule by element: fire signs begin from Mesha, earth signs from Makara, air signs from Tula and water signs from Karka. Because 3°20' is exactly one nakshatra pada, the 108 padas of the zodiac map onto the navamshas in order. Mesha 0° to 3°20' (Ashwini pada 1) is Mesha navamsha; Mesha 3°20' to 6°40' is Vrishabha navamsha, and so on.
Worked example: Shukra at 18° Simha. Simha is fixed, so its navamshas start from the 9th sign, Mesha. 18° falls in the sixth navamsha (16°40' to 20°00'), which is the sixth sign from Mesha: Kanya. Shukra is debilitated in Kanya, so a Simha Shukra at 18° sits in its sign of debilitation in D9.
Vargottama
A planet in the same sign in D1 and D9 is called vargottama. It occurs in the first navamsha of movable signs, the middle (fifth) navamsha of fixed signs and the last navamsha of dual signs. Vargottama planets, and a vargottama lagna, are generally read as strengthened and consistent in their results.
Reading D9 in practice
A working order many practitioners follow:
- Dignity check. For each planet that matters to the question, compare its dignity in D1 and D9: exalted, own sign, friendly, enemy or debilitated. A planet that improves in D9 tends to deliver more over time; one that weakens tends to deliver less than D1 suggests.
- D9 lagna and its lord. The Navamsha lagna and its lord describe the inner strength of the chart and are read carefully for marriage questions.
- Marriage and partnership. Read the 7th house of D9, its lord, and the condition of Shukra (and Guru, in many traditions, for a woman's chart). D9 is weighed with the D1 7th house, never alone.
- Dasha lords. A mahadasha lord well placed in D9 tends to give steadier results in its period.
- Neecha bhanga and dignity changes. Note where a debilitated D1 planet gains dignity in D9; many teachers count this among the supports for cancellation of debilitation.
Birth-time sensitivity
The Navamsha lagna changes roughly every 12 to 13 minutes, so D9 is more sensitive to birth time than D1. If the D9 lagna sits near a navamsha boundary, say so in the reading and treat lagna-based D9 conclusions with care. Planet positions in D9 are far less sensitive, except for the Moon near a boundary.
Seeing it on the desk
On Bodhlok, D9 opens beside D1 by default in the divisional charts view, with vargottama planets marked. The full Shodashavarga is one click away when the question calls for D10, D7 or D60. Calculations use the Swiss Ephemeris with your chosen ayanamsa.

Frequently asked questions
What is the Navamsa chart?
The Navamsa (D9) is the ninth divisional chart. It divides each sign into nine parts of 3°20' and is read beside D1 to judge planetary strength, marriage and the spouse.
How is the Navamsa calculated?
Each sign is split into nine 3°20' parts. Counting starts from the same sign for movable signs, the 9th sign for fixed signs and the 5th sign for dual signs.
What does vargottama mean?
A planet is vargottama when it occupies the same sign in D1 and D9. It is generally considered strengthened and consistent in its results.
Is D9 more important than D1?
D1 shows the promise of the chart and D9 shows how well planets can deliver it. Practitioners read them together; D9 is not a substitute for D1.
Why does my Navamsa lagna change between software?
The D9 lagna changes every 12 to 13 minutes, so small differences in birth time or ayanamsa can move it. Check both settings before comparing.
