What is a Divisional Chart?

A divisional chart, called a varga or amsa chart in Sanskrit, is a secondary chart produced by cutting each of the twelve signs of the birth chart into a fixed number of equal parts and mapping those parts onto a new set of twelve signs. The birth chart itself — the D1 or rashi chart — remains the foundation. Everything else is derived from it by arithmetic, not by any additional observation of the sky.

The convention for naming them is simple. The number after the letter D states how many parts each sign is cut into: D9 divides each sign into nine parts of 3 degrees 20 minutes, D10 into ten parts of 3 degrees, D60 into sixty parts of 30 minutes each. The higher the number, the finer the slice and the more sensitive the resulting chart is to the recorded birth time.

Why the Same Birth Data Yields Many Charts

A planet sitting at 12 degrees of Taurus and another at 27 degrees of Taurus share the same sign in the rashi chart, and a purely sign-based reading treats them as broadly alike. The divisional scheme refuses that flattening. Because the divisions cut across the sign, those two planets land in different amsas and therefore in different signs of the D9, the D10 and every other varga. The exact degree, which the rashi chart records but does not otherwise exploit, becomes the deciding factor.

This is why classical texts treat the vargas as a magnifying instrument rather than as independent horoscopes. In Vedic each divisional chart is computed from the same underlying planetary longitudes as the D1, so nothing new is introduced — the same positions are simply read at a finer resolution. Astrologers of the Brihat Parashara Hora Shastra tradition hold that a planet strong in the rashi chart but weak across the vargas gives less than its position promises, while one that repeats well across several divisions is considered genuinely capable of delivering results.

The Shodashavarga: Sixteen Divisions

Parashara enumerates a canonical set of sixteen divisional charts known as the Shodashavarga. Each is assigned a domain of life, and the tradition holds that questions belonging to that domain are examined in the corresponding varga rather than in the rashi chart alone.

D1 Rashi — the birth chart itself; body, overall life and the frame for everything else.
D2 Hora — wealth and accumulated resources.
D3 Drekkana — siblings, courage and initiative.
D4 Chaturthamsa — property, fixed assets and domestic fortune.
D7 Saptamsa — children and progeny.
D9 Navamsa — marriage, the spouse and dharma; the most consulted varga after the D1.
D10 Dasamsa — career, profession and standing in public life.
D12 Dwadasamsa — parents and ancestry.
D16 Shodasamsa — vehicles, comforts and general happiness.
D20 Vimsamsa — spiritual practice, worship and devotion.
D24 Chaturvimsamsa — education, learning and scholarship.
D27 Bhamsa — inherent strengths and weaknesses; also called Nakshatramsa.
D30 Trimsamsa — misfortune, adversity and moral character.
D40 Khavedamsa — auspicious and inauspicious effects, traditionally read for the maternal line.
D45 Akshavedamsa — conduct and character, traditionally read for the paternal line.
D60 Shashtiamsa — the finest division, treated as a summary of accumulated past merit.

Smaller working sets are also standard. The Shadvarga uses six divisions, the Saptavarga seven and the Dashavarga ten, each a subset of the sixteen. Practitioners who do not use the full sixteen typically settle on the D1, D9 and D10 for everyday work and reach for the remainder when a specific question calls for one.

How Divisional Charts are Read

Establish the rashi chart first. A promise absent from the D1 is not created by a varga.
Move to the varga governing the question — the D10 for a career question, the D7 for children.
Examine the lord of the relevant house in the D1 and see where it lands in the varga.
Note planets that hold the same sign in both charts, called vargottama, considered a mark of consistency.
Bring in timing through the dasha periods, since a varga describes quality but not the moment of a result.

Because the finer divisions slice a sign into very small arcs, an error of a few minutes in the recorded birth time can move a planet from one amsa to the next. This sensitivity increases with the divisor, which is why the D60 is regarded as demanding an unusually accurate birth time. It also means the choice of ayanamsha matters more here than in the rashi chart; you can compare the values on the ayanamsha calculator. To generate a chart and its divisions, use the Kundali section.

Frequently Asked Questions

Are divisional charts separate horoscopes?

No. They are derived arithmetically from the same planetary longitudes as the birth chart and carry no independent data. The tradition treats them as a closer view of the rashi chart rather than as alternative charts, which is why a reading normally begins with the D1 and moves outward.

How many divisional charts should be used?

There is no fixed rule. Classical texts describe the full Shodashavarga of sixteen, but most practising astrologers work primarily with the D1, D9 and D10 and consult others as the question requires. In Vedic the full set is available so a chart can be examined at whatever depth is wanted.

Why do my divisional charts change with a small change in birth time?

Because each division cuts a 30-degree sign into equal parts, and the finer the division the smaller each part. In the D60 each part spans only 30 minutes of arc, so a birth time out by a few minutes can shift several planets. Coarser divisions such as the D2 and D3 are far more tolerant.

What does vargottama mean?

A planet is vargottama when it occupies the same sign in a divisional chart as it does in the rashi chart. The term is used most often for the D9. Tradition regards it as a sign of stability and strength, since the planet's expression does not change character between the two levels of view.
