Divisional Charts (Vargas)

Building the Navamsa

Nine parts to a sign, 108 to the zodiac — and you already know the arc.

3°20′, and where you've seen it

The navamsa divides each sign into nine. 30° ÷ 9 = 3°20′ per part.

That number should look familiar. A nakshatra pada is also 3°20′ — a nakshatra (13°20′) divided by four.

That is not a coincidence. A navamsa and a nakshatra pada are the same arc. Both grids start at 0° Aries and step by 3°20′, so they line up exactly, all the way round.

108, from both directions

Count them either way and you land in the same place:

• 12 signs × 9 navamsas = 108
• 27 nakshatras × 4 padas = 108

The Nakshatras track told you "pada is the doorway into the navamsa" and left it there. This is the door: a graha's nakshatra pada tells you its navamsa sign directly. If you know the pada, you know the D9 placement — no further arithmetic.

The rule that makes the grid uniform

Classically the rule is stated by modality — the navamsa count starts from the same sign for a movable sign, the 9th for a fixed sign, and the 5th for a dual sign.

Those three separate-sounding rules are one rule in disguise. Lay the 108 navamsas end to end from 0° Aries and just count: the n-th navamsa is simply sign number n mod 12. The movable/fixed/dual offsets fall out automatically, because the grid is uniform.

That's exactly how the engine computes it: find which of the 108 arcs the longitude falls in, then take that index modulo 12.

Worked example

The Moon at 8° Taurus.

Taurus is a fixed sign, so its navamsa count starts from the 9th sign from Taurus — Capricorn.

8° into the sign, at 3°20′ per navamsa: 8 ÷ 3⅓ = 2.4, so we're in the 3rd navamsa of Taurus.

Counting three from Capricorn: Capricorn (1), Aquarius (2), Pisces (3).

So a Moon at 8° Taurus sits in Pisces navamsa. Cross-check by pada if you like — 8° Taurus is in Krittika pada 4, whose navamsa is Pisces. Same answer, two routes.

The D9 lagna

The ascendant is divided the same way as everything else. Whatever navamsa the rasi lagna's degree falls in becomes the D9 lagna — and from that, the D9's houses are counted exactly as usual.

This is why the D9 needs a good birth time twice over: the lagna moves about 1° every four minutes, so four minutes of error can shift both the lagna's navamsa and every house in the chart.

Remember it

A navamsa is a pada is 3°20′; 12 × 9 = 27 × 4 = 108. Know the pada, know the D9 sign — the two grids are the same grid.

Terms introduced here

How the navamsa is built

Each sign splits into 9 parts of 3°20′ — the same span as a nakshatra pada. 12 × 9 = 108 navamsas around the zodiac.

Padas are the doorway

A nakshatra pada and a navamsa are the same 3°20′ arc, which is why pada tables give the D9 sign directly.

What the D9 shows

Marriage and partnership, dharma, and a graha's inner strength — the promise behind the rasi chart's appearance.
