Vargas and the Navamsa chart
Sixteen charts from one birth moment — and the arithmetic problem that creates.

The short answer
Vargas are divisional charts, produced by subdividing each 30-degree sign into equal parts and mapping those parts onto a new chart. The Navamsa or D-9 divides each sign into nine parts of 3°20' and is by far the most used, consulted for marriage and for the underlying strength of planets. Sixteen standard vargas exist, each addressing a different area of life, and each is derived from the same birth moment rather than from new information.
How a divisional chart is made
Take the Navamsa. Each 30-degree sign divides into nine parts of 3°20' each. A planet's position within its sign determines which of those nine parts it falls in, and each part maps to a sign in the new chart by a fixed rule.
So a planet at 5° of a sign falls in the second navamsa; one at 25° falls in the eighth. Both are in the same sign in the main chart and in different signs in the D-9.
This is why divisional charts are so sensitive to birth time. A small error in the birth moment moves planets slightly in the main chart and can move them an entire sign in the D-9 — and further still in higher divisions.
The main vargas
| Chart | Divides each sign into | Traditionally read for |
|---|---|---|
| D-1 Rashi | 1 — the main chart | Everything; the basis of all the rest |
| D-2 Hora | 2 | Wealth |
| D-3 Drekkana | 3 | Siblings |
| D-4 Chaturthamsa | 4 | Property and fortune |
| D-7 Saptamsa | 7 | Children |
| D-9 Navamsa | 9 | Marriage, and underlying planetary strength |
| D-10 Dasamsa | 10 | Career and public standing |
| D-12 Dwadasamsa | 12 | Parents |
| D-16 Shodasamsa | 16 | Vehicles, comforts |
| D-20 Vimsamsa | 20 | Spiritual practice |
| D-24 Chaturvimsamsa | 24 | Education and learning |
| D-30 Trimsamsa | 30 | Misfortune and difficulty |
| D-60 Shashtiamsa | 60 | Everything, at the finest resolution |
Sixteen vargas are standard, and the list above covers the ones most commonly used. Practitioners vary in how many they consult; many work primarily with D-1, D-9 and D-10.
Why the Navamsa is special
Two reasons it outranks the other divisions.
It is read for marriage, which is the single most common reason people consult a Jyotisha practitioner in traditional contexts. The D-9 is examined alongside the main chart in match-making.
It is read for underlying strength. A planet that looks weak in the main chart but strong in the Navamsa is described as vargottama when it occupies the same sign in both — a condition treated as a significant strengthening.
Some practitioners describe the D-9 as showing the chart's inner reality against the D-1's outer one, and treat a substantial divergence between them as itself informative.
The combinatorial problem
This is the honest difficulty and it is worth stating plainly.
Sixteen divisional charts, each with nine planets across twelve signs and twelve houses, generated from a single birth moment. That is a very large number of placements, and none of them contains information that was not already in the original chart — they are all arithmetic transformations of the same degrees.
With that many derived placements, a practitioner can find support for almost any reading. If the main chart does not show what is expected, a varga will. This is the same structural problem as yogas — an apparatus elaborate enough that something always fits.
It compounds with the precision issue above. The higher divisions demand a birth time accuracy that most people simply do not have, so the finest distinctions are frequently being drawn from rounded data.
The defence, fairly stated
Practitioners would say the vargas are not independent evidence but magnification — a way of examining one area of life at higher resolution, in the same way you might read a Western chart's fifth house closely when asking about creativity.
That is a reasonable framing, and it makes the vargas a lens rather than a second opinion. Under it, a D-9 that disagrees with the D-1 is not two conflicting readings but one reading examined at two scales.
AsterNym does not compute vargas, because it does not compute sidereal charts at all. For those you want a Jyotisha tool — see Far Far Away astrology, which produces D-9 and D-10 among others.
Common questions
- What is a Navamsa chart?
- The D-9 divisional chart, produced by dividing each 30-degree sign into nine parts of 3°20' and mapping each to a sign in a new chart. It is the most used varga, consulted for marriage and for the underlying strength of planets.
- What are vargas in Vedic astrology?
- Divisional charts derived from the main chart by subdividing each sign into equal parts. Sixteen are standard, each traditionally read for a different area — D-7 for children, D-10 for career, D-24 for education — and all are arithmetic transformations of the same birth positions.
- What does vargottama mean?
- A planet occupying the same sign in both the main chart and the Navamsa. It is treated as a significant strengthening, indicating consistency between the outer chart and the underlying one.
- Do divisional charts need a precise birth time?
- Increasingly so as the division rises. The D-9 amplifies birth time errors ninefold, and the D-60 divides each sign into thirty-arcminute segments, where a two-minute error can change a planet's sign — finer than most recorded birth times can support.
