The Sixteen Divisions: What a Varga Chart Actually Measures

Most students hit the same wall at the same point. You have learned the twelve bhavas, the seven grahas and the two nodes, the aspects, the lordships. You can look at a rasi chart and say something true about a person. Then somebody opens a navamsa beside it and the floor tilts. The planets and the lagna are in different signs. Jupiter, so nicely placed a moment ago, is now in the eighth. Someone tells you this is the marriage chart, and you are holding two charts that seem to disagree with no rule for which one wins.

The divisions are not the cause of that confusion. The cause is a bad mental model that spreads faster than the correct one, because it fits in a sentence while the corrective takes a paragraph. This article is that paragraph.

A varga magnifies one department of the same chart

The rasi chart, the D1, is the whole map. Every promise a nativity contains is already written there. The sixteen vargas do not add promises. They resolve them.

Consider what a division does arithmetically. A sign is thirty degrees wide. Cut it into nine equal parts and re-project each onto a full sign, and you have stretched a three degree twenty minute slice of sky across thirty degrees. Nothing new entered the system; you changed the scale. Two people born eleven minutes apart can share every rasi placement and diverge completely in the navamsa, and the navamsa is not inventing that difference, it is exposing one the coarser scale could not represent.

So the working principle I teach is this: a planet's rasi position is its cause, its varga position is its expression inside a named department of life. Saturn in the rasi tells you what Saturn is and where it stands in the life as a whole. Saturn in the dasamsa tells you how that same Saturn behaves in work and public position. The graha did not move. Your question got narrower, and the chart answered at the required resolution.

The texts assume this rather than announcing it. Through the dasa chapters of Brihat Parashara Hora Shastra one pattern repeats: Parashara states the result of a period, then attaches conditions, and among them is almost always whether the planet sits in its own or exalted navamsa. The condition never stands alone. It is a qualifier stacked on a rasi statement, which is exactly how a magnification is used.

A varga also cannot manufacture what the rasi does not promise. If the fifth house, its lord and Jupiter are all wrecked in the D1, a beautiful saptamsa does not deliver children. It says only that whatever progeny karma exists will meet less obstruction. The varga modulates. The rasi originates.

The sixteen divisions and the department each one measures

Parashara names sixteen divisions and calls the set the Shodasavarga. Several carry more than one name in the literature, a real source of confusion when you move between books and software.

Two entries need an honest footnote. Parashara assigns the khavedamsa to auspicious and inauspicious effects generally, and gives the akshavedamsa and shashtiamsa jointly to all general indications. The now common attribution of D40 to the maternal line and D45 to the paternal line is not in the plain text. It is a later refinement, reading the two as the karmic inheritance received from the mother's side and from the father's side. I use it, because it holds up in practice, but I tell students plainly that it is a modern emphasis, not a Parashari sutra. Knowing which of your rules came from where is the difference between a practitioner and a repeater.

The shashtiamsa deserves separate comment. Each division is thirty minutes of arc, and Parashara attaches sixty named characters to them, some benevolent and some frankly terrible, running in one order for odd signs and reversed for even. He gives the working rule directly: a house whose lord falls in a malefic shashtiamsa is diminished in what it signifies, illustrated with cases as specific as a tenth lord in the Bhrashta shashtiamsa producing a wretched working life.

How each division is actually cut

The classical texts give a general rule that collapses most of the arithmetic into one line. Express the planet's longitude within its sign in minutes of arc, a value between zero and 1800. Multiply by the divisor, divide by 1800, and the whole number part plus one tells you which amsa the planet occupies.

That gives the index. Where the count begins is a separate rule, different for almost every varga. Here is the Parashari set.

Hora splits the sign in half: in an odd sign the first fifteen degrees belong to the Sun and the second fifteen to the Moon, reversed in an even sign. Drekkana takes ten degree thirds, ruled by the lords of the first, fifth and ninth signs from the sign itself. Chaturthamsa takes seven and a half degree quarters, counted from the sign itself, then the fourth, seventh and tenth from it. Saptamsa counts from the sign itself in an odd sign and from the seventh in an even one. Navamsa counts from the sign itself for a movable sign, from the ninth for a fixed sign and from the fifth for a dual sign. Dasamsa counts from the sign itself in odd signs and from the ninth in even ones. Dwadasamsa always counts from the sign itself.

Beyond the twelfth the rules switch to fixed anchor points. Shodasamsa begins from Aries for movable signs, Leo for fixed and Sagittarius for dual. Vimsamsa begins from Aries for movable, Sagittarius for fixed and Leo for dual, a different pairing from the shodasamsa and a common place for a silent error. Chaturvimsamsa begins from Leo in odd signs and Cancer in even. Bhamsa begins from Aries for fiery signs, Cancer for earthy, Libra for airy and Capricorn for watery. Khavedamsa begins from Aries in odd signs and Libra in even. Akshavedamsa begins from Aries for movable, Leo for fixed and Sagittarius for dual.

Two divisions break the pattern. The trimsamsa does not divide equally: in an odd sign the thirty degrees go as five to Mars, five to Saturn, eight to Jupiter, seven to Mercury and five to Venus, and in an even sign the same allotments run in reverse from Venus. The luminaries own no trimsamsa, a deliberate statement about what this division measures. Parashara does not leave you stranded there, and this is the part summaries drop: for trimsamsa purposes he reads the Sun as Mars behaves and the Moon as Venus behaves, and he allows both an exaltation trimsamsa, the Sun in Aries and the Moon in Taurus. The shashtiamsa has its own recipe: multiply the degrees traversed inside the sign by two, divide by twelve, keep the remainder, add one, and count that many signs forward from the planet's sign.

The size of an amsa sets your birth time tolerance, which deserves an engineer's attention. The ascendant moves roughly one degree every four minutes, though the real rate swings widely with latitude and rising sign. A navamsa is three degrees twenty minutes wide, so the navamsa lagna changes about every thirteen minutes. A chaturvimsamsa is one degree fifteen minutes, about five minutes of clock time. A shashtiamsa is thirty minutes of arc, roughly two. If a birth time is recorded to the nearest quarter hour, as most Indian birth times before the nineteen nineties are, your D60 lagna is noise. Reading past the limit of your instrument costs the client.

The navamsa is the chart of dharma, and the spouse lives there for a reason

The single most repeated error I meet is calling the D9 the marriage chart. I hear it from students in their first week and from working astrologers who have been charging for readings for a decade, and it has produced an enormous amount of bad counsel, because it inverts cause and effect.

Navamsa means ninth part, and the ninth is dharma bhava, the house of dharma and fortune with Jupiter as its karaka. The ninth division carries that meaning up to the level of a whole chart. The navamsa shows what sustains you: the strength that holds the life upright, the fruit that ripens from what the rasi promised. That is why the dasa rules keep asking whether a planet is in its own or exalted navamsa. They are asking whether it has anything sustaining it when its period arrives.

The spouse appears there because in the classical scheme the spouse is a dharma partner. Marriage is a samskara that makes dharma possible, and the person you marry sustains, or fails to sustain, the life you are meant to be living. Read the D9 as the chart of sustenance and the spouse falls out of it as one of the things sustained.

The practical difference is immediate. If a client asks about a career decision and their navamsa lagna lord is broken, that matters, though the question has nothing to do with marriage. It says they will lack the support to hold the position once they have it. The rasi grants the job; the navamsa refuses to hold it. Filed under marriage, the D9 would have told you nothing.

There is a classification inside the navamsa that almost nobody runs. Parashara labels the nine amsas of every sign Deva, Manushya and Rakshasa, divine, human and demonic, cycling three times through the sign, movable signs beginning at Deva, fixed at Manushya, dual at Rakshasa. A planet's navamsa therefore carries a temperament as well as a sign, and a Rakshasa navamsa colours how the planet takes what it wants. Texture rather than verdict, but when two charts look alike and behave differently, it is one of the first places I look.

Vargottama placements, chara karaka positions and the karakamsa all live here too. The karakamsa is the navamsa sign occupied by the atmakaraka, the planet at the highest degree, and Parashara treats it as a lagna in its own right, reading houses from it and testing raja yogas against it as he does from the birth lagna. That method has no relationship to marriage. I have set out the karaka scheme in the soul's agenda as the chara karakas describe it.

Modern practice puts far more weight on the vargas than most classical commentators did, reading the navamsa as a full chart of the fruit of karma with its own lagna, kendras, trikonas and arudhas. The older commentarial habit is thinner, treating it as a strength modifier attached to a rasi statement and nothing more. I sit closer to Rath, because a structured D9 produces claims specific enough to be wrong, and they have held up when I tested them against dated events. What I will not do is read the navamsa as if the D1 were not there. The navamsa answers a question the rasi asked. It does not ask its own.

Vargottama, and the grades of delivery

A planet is vargottama when it occupies the same sign in the rasi and in the navamsa. The older material states it positionally, a useful way to hold it: the first navamsa of a movable sign, the fifth of a fixed sign, the ninth of a dual sign.

Vargottama removes a mismatch. Ordinarily a planet's rasi sign and its navamsa sign differ, so cause and sustaining condition speak two languages and something is lost between them. A vargottama planet has no translation loss, and it delivers cleanly. The longevity mathematics agrees: in Amsayurdaya a planet's contribution is doubled when it is vargottama, alongside own sign, own drekkana and own navamsa. A multiplier, applied to whatever the planet already was.

Two separate three step gradings sit near this doctrine and are constantly confused, including by me for longer than I would like to admit. The first is a dignity ladder. The classical texts state it of the Moon: the effect is full when it is vargottama, medium in its own navamsa, slight in another's. That grades whose amsa the planet landed in.

The second is positional. Parashara says the effect of a hora is full at its beginning, middling in its middle and absent at its end, and that the same holds for the drekkana, the chaturthamsa and the navamsa. That grades where inside the amsa's span the planet sits. The two rules are independent and they stack, so a planet in its own navamsa but sitting in the last few minutes of that navamsa's arc is a weaker claim than the dignity alone suggests. It is the most useful classical rule I know that almost no software surfaces, and it puts a floor under the birth time argument: if your time is soft by ten minutes you cannot tell the start of a navamsa from its end, so the positional grading is unavailable to you.

Now the correction that keeps people from misusing vargottama. It is an amplifier, not a blessing. A planet debilitated in the rasi and vargottama is debilitated twice, cleanly, with nothing lost. One line of practice holds that vargottama cancels debility outright. I do not follow that reading, and I have not seen it hold in the charts I have run. What I have seen is a difficulty produced with unusual consistency, which is different from cancellation and occasionally more workable, since a consistent difficulty can be diagnosed. Neechabhanga is a separate doctrine with its own conditions, and folding vargottama into it muddies both.

The texts back the amplifier reading and they also record its failure mode. Parashara says a lagna lord in vargottama gives a body that resists disease, and that a strong vargottama Moon receiving four or more aspects raises a person to rulership. Another classical treatment states that rule differently, extending it to the lagna as well as the Moon and asking for five or six aspects, worth knowing if you quote a number to a student. And the classical texts add the exception that settles the argument: a vargottama lagna that no planet aspects causes the chart's raja yogas to fail. Vargottama amplifies what arrives, and if nothing arrives it amplifies nothing.

Vimsopaka Bala: putting a number on consistency across the divisions

Parashara gives a scoring method that converts a planet's performance across a set of divisions into one number out of twenty. Vimsopaka Bala is among the more genuinely quantitative instruments in classical Jyotish. It needs a weighting for each division and a score for the planet's relationship with the lord of the sign it lands in there.

That relationship score, the varga viswa, runs out of twenty. Own sign, moolatrikona or exaltation scores the full twenty. A great friend's sign scores eighteen, a friend's fifteen, a neutral's ten, an enemy's seven and a bitter enemy's five. Those five grades are the compound relationship, natural friendship combined with temporary, and you read them from the rasi chart rather than recomputing them inside each division, a convention Parashara states plainly when he sets up the saptavargaja component of Shadbala. Get that one wrong and every number you produce is quietly different from everyone else's, which is the sort of detail that silently divides two implementations while both look correct.

Parashara defines four groupings. The shadvarga is the set of six: rasi, hora, drekkana, navamsa, dwadasamsa and trimsamsa, weighted six, two, four, five, two and one. The saptavarga adds the saptamsa. The dasavarga adds dasamsa, shodasamsa and shashtiamsa to those seven, weighted three for the rasi, five for the shashtiamsa, one and a half for each remaining eight. The shodasavarga is all sixteen, weighted three and a half for the rasi, four for the shashtiamsa, three for the navamsa, two for the shodasamsa, one each for hora, drekkana and trimsamsa, half a point for each remaining nine. Every set sums to twenty.

The saptavarga weights are where I have to stop and admit a textual problem. Adding the saptamsa forces the other six down, and printed editions disagree about how. Santhanam's English Parashara, the copy most Indian students own, gives rasi five, hora two, drekkana three, dwadasamsa two, trimsamsa one, saptamsa four and a half and navamsa two and a half. Other printings and several software packages swap the last two, putting four and a half on the navamsa. Both total twenty and both are in circulation.

I argued for years that the navamsa must take the higher weight, on the grounds that Parashara never promotes a newly added division above the navamsa. That argument is wrong, and I dropped it once I checked the other schemes: in the dasavarga the newly added shashtiamsa takes five while the navamsa falls to one and a half, and five is above even the rasi. All that survives is a preference for the gentler degradation from the shadvarga, thin evidence to hang a rule on. So compute both. The two readings move two points of weight between two divisions, which bounds the disagreement exactly: the totals can differ by at most one and a half points out of twenty, and only when the planet sits at opposite extremes in those divisions, own sign in one and a bitter enemy's in the other. That matters only near a band boundary, and there you quote a range rather than a number.

The computation itself is simple. For each division, multiply its weight by the varga viswa the planet earned there and divide by twenty, then sum. Parashara's bands: below five the planet gives no good result worth naming, five to ten partial, ten to fifteen moderate, above fifteen it delivers fully. A parallel scheme instead counts how many good vargas a planet occupies, climbing in the dasavarga from Parijata at two up to Sridhama at ten.

Which divisions count as good is defined precisely. Exaltation, moolatrikona and own sign qualify. So do divisions owned by the lords of the four kendras from the arudha lagna, tying a strength calculation to the chart of appearance rather than the lagna alone. I have written about the gap between what you are and what the world perceives, and this is one of the places Parashara quietly builds the arudha into a computation most people run without it.

The counterweight is stated just as firmly. The divisions of a combust planet, one defeated in graha yuddha, a weak planet or one in a poor avastha do not count as auspicious, and such placements can destroy yogas that would otherwise have delivered. A high Vimsopaka score sitting on a combustion is a number that lies, the same failure Shadbala produces when read carelessly, which I have taken apart in the difference between a strong planet and a capable one.

The reading method: start in the rasi, finish in the varga

The sequence I teach is deliberately rigid, because the discipline is the point.

Fix the question first, and from the question fix the house. Career means the tenth, children the fifth, property the fourth. Formal education means the fourth and fifth together, one the schooling and the other the intelligence. Spiritual practice means the ninth and twelfth, with the fifth for mantra. Naming the house in advance also stops you opening division after division until one says yes.

Read that house fully in the rasi: its occupants, its lord and where the lord sits, the karaka for the matter and its condition, the aspects arriving, the argala and its obstruction. This is the cause layer, and everything you conclude later must stay consistent with it.

Now open the varga and find the same lord in it. Not a new planet, the same one. Ask four things. What sign has it landed in, its own, a friend's or an enemy's. Where does it sit from the varga lagna. What is it with, and what aspects it. And is it vargottama. Then read the varga lagna and its lord as the person's own position inside that department: in the dasamsa the native as a working professional, in the saptamsa the native as a parent. That is a different object from the rasi lagna lord and may be in a different state.

Only after all of that should you look at the varga's own tenth, or fifth, or whichever house is natural to the matter. Treating the tenth of the dasamsa as the main career signal is the commonest way to get a career reading badly wrong, because it detaches the division from the chart that generated it.

Then grade the outcome. Rasi promises and varga confirms: expect delivery. Rasi promises and varga refuses: expect something that arrives late, arrives smaller, or fails to hold.

One timing refinement lives in the vargas and is almost never used. Parashara says a planet in the first drekkana of its sign gives its dasa results at the beginning of the period, in the second toward the middle, in the third toward the end. For a retrograde planet the order reverses, so its third drekkana results arrive first, and since Rahu and Ketu count as permanently retrograde they always run in reverse. That rule sharpens a great many period readings and costs nothing to check. It belongs with the material on how to read a period rather than merely name it.

Where practitioners go wrong

The first failure is confusing varga dignity with strength. A planet exalted in the dasamsa is well disposed inside the career department, which speaks to the quality of its expression there rather than to its capacity to act. The two behave differently in the life, and I see them conflated constantly, in software summaries and in consultations both. Dignity tells you how the thing goes when it goes. Strength tells you whether it moves at all.

The second is a software problem rather than a doctrinal one. The trimsamsa's unequal division and the shashtiamsa's parity rule are handled inconsistently across programs, and the vimsamsa and shodasamsa starting signs are easy to transpose, since they use the same three anchor signs in a different order. Before building a judgement on a D20 or D30, verify one placement by hand.

The third is treating the D2 as a twelve sign chart when the Parashari hora does not produce one. There are twenty four horas across the zodiac but only two lords, so every planet lands in Leo or Cancer and the hora is a two bucket sort read by rule, not by house. The rules are specific: the Sun, Mars and Jupiter do well in the Sun's hora, every planet except Mercury does well in the Moon's hora, and Mercury does well in both, with a parity refinement that the male grahas gain in the Sun's hora especially in odd signs while the Moon, Venus and Saturn gain in the Moon's hora especially in even signs. That is the whole instrument, and it speaks to the source of sustenance rather than to the amount of it. Modern practice also runs an expanded hora that spreads the planets across all twelve signs and can be read as a proper chart with houses and lords. The classical text does not go that far, and I keep the two apart in my own work instead of blending them, because a rule proved on one of them does not transfer to the other. Two instruments, one name. Know which one your software drew before you say anything about wealth.

What to look at in your own chart this week

Start with one thing, not sixteen. Find your navamsa lagna and its lord, then locate that lord in your rasi chart. That pairing will tell you more about what sustains your life than any list of varga placements, because it links the sustaining condition to a concrete cause.

Then check whether any planet is vargottama. Note its rasi condition honestly, including when that condition is poor, and note whether anything aspects it, since an unaspected vargottama is the sealed case the classical texts warn about. A vargottama planet is unusually consistent, and consistency is the easiest thing to verify in your own life, which makes it the best place to test a doctrine rather than believe it.

Third, take one department that matters to you now, name its house, find that house's lord, and follow that single lord into the one relevant division. One lord, one division. Write down what you expect before events arrive, and date the note. Prediction written after the fact is not prediction.

If your birth time is uncertain, write down how wide the uncertainty is and decide which divisions that permits. A time good to five minutes supports the navamsa and the dasamsa. A time good to half an hour supports neither, and the honest move is to rectify before going further. Knowing the limit of your instrument is the first discipline of this practice, and the one that keeps the shastra clean.
