Ashtakavarga: SAV, BAV and What Bindus Mean

Most chart reading is qualitative. A planet is called strong or weak, a house well placed or afflicted, and two astrologers can look at the same chart and grade it differently. Ashtakavarga is the classical answer to that problem: it turns the chart into numbers. Parashara devotes five chapters to it (BPHS 66-70), and one of its rules — how to grade a transit — is among the most used techniques in all of Jyotish.

What Ashtakavarga actually is

The name means "eight divisions", and the eight are the seven visible planets plus the Ascendant. Each of those eight looks at every sign of your chart and votes: supportive, or not. A supportive vote is a bindu (a dot or point); the absence of one is marked as a rekha (a line). Count the votes and every sign in your chart carries a number instead of an adjective.

The votes are not opinions. Each contributor gives its bindu in a fixed list of houses counted from itself, laid down in BPHS chapter 66. In the Sun's own Ashtakavarga, for example, the Sun contributes a point in the 1st, 2nd, 4th, 7th, 8th, 9th, 10th and 11th from itself, and the Moon contributes in the 3rd, 6th, 10th and 11th from the Moon. Every planet has its own such table for every contributor.

Bhinnashtakavarga (BAV): one planet's own scorecard

A Bhinnashtakavarga is the bindu chart of a single planet. Because eight contributors each vote once per sign, a sign can hold at most 8 bindus in any one planet's BAV, and at minimum 0. Read across the twelve signs, a BAV tells you where in the zodiac that particular planet is supported — and, as we'll see, where its transits tend to land well.

Sarvashtakavarga (SAV): the 337-point picture

Add the seven planetary BAVs together sign by sign and you get the Sarvashtakavarga. The totals are fixed by the tables themselves, which is a useful check on any calculator:

Those 337 points spread across 12 signs, so the average sign holds about 28. If your calculator's SAV does not total exactly 337, its tables are wrong.

How to read a sign's SAV score

Against that average of 28, the convention in common use runs:

• Above 30 — a well-supported sign, and the house it occupies tends to carry its matters more easily.
• 25 to 29 — ordinary; results follow the rest of the chart and the running period.
• Below 25, and especially below 20 — a sign that asks for more effort than it gives back.

Treat these bands as a reading convention rather than a verse: the classical chapters give effects house by house rather than a numeric scale. What the numbers do reliably is rank — they tell you which areas of your chart are best and least supported relative to each other.

Signs, houses, and which one you are reading

Bindus attach to signs. The house they represent depends on your ascendant. If Libra holds 34 bindus and Libra is your 7th house, it is partnership that carries the support. This is why two people with identical SAV numbers can read completely differently, and why a bindu count means nothing until you lay it over a chart. Our free Ashtakavarga calculator does both: the SAV grid by sign and the house each sign rules for you.

The transit rule Ashtakavarga is famous for

This is the technique that keeps the system alive in daily practice. When a planet transits a sign, you look up that sign in that planet's own BAV. Parashara states it as the inverse — the marked (dotless) houses are where the planet's transit yields unfavourable results, and the rest do not (BPHS 66). In working terms:

• 5 or more bindus — the transit tends to deliver on that planet's significations.
• 3 to 4 — mixed, decided by the rest of the chart.
• 0 to 2 — the transit tends to strain or under-deliver.

It matters most for the slow movers, because they sit in a sign long enough for the difference to be felt: see Saturn's transit and Jupiter's transit for how each is read.

Trikona Shodhana: the first reduction

Before using the numbers for finer work, classical practice applies two reductions. The first, trikona shodhana, works on the four triangles of signs: Aries-Leo-Sagittarius, Taurus-Virgo-Capricorn, Gemini-Libra-Aquarius and Cancer-Scorpio-Pisces (BPHS 67). Within each triangle, the lowest figure is subtracted from all three — so three equal figures all become zero. Where one of the three already holds nothing, no reduction is made at all. The effect is to strip out the support a chart holds in common across a triangle and leave what is distinctive.

Ekadhipatya Shodhana: the second reduction

The second, ekadhipatya shodhana, handles the fact that five of the seven planets rule two signs each (BPHS 68). Where one planet owns two signs, the two figures are reduced against each other, and the treatment depends on whether each sign is occupied by a planet or empty — six cases in all. It is skipped when one of the two signs has already been reduced to nothing, and it does not apply to the Sun and Moon, which own one sign each. Both reductions feed the longevity and finer predictive methods rather than everyday reading — most practical work, including transit grading, uses the unreduced figures.

Kaksha: the finest transit division

A later refinement, widely used in transit work but not part of Parashara's chapters, divides each 30° sign into eight kakshas of 3°45', one for each contributor in a fixed order. As a planet crosses a sign it passes through all eight in turn, and each kaksha either holds that contributor's bindu or does not. The claim is that results within a single sign rise and fall as the planet moves between marked and unmarked kakshas. Treat it as what it is: a refinement of the tradition rather than a rule from BPHS.

Ashtakavarga is not Shadbala

The two get confused because both produce numbers. They measure different things. Shadbala (BPHS 33) grades a planet: six sources of strength — positional, directional, temporal, motional, natural and aspectual — added up in units called rupas. Ashtakavarga grades a sign, by counting how many of the eight contributors support it. A planet can be strong in Shadbala while sitting in a sign with few bindus, and the two readings are both true: the planet has power, the ground it stands on offers little help. Our free Shadbala calculator produces the other half of that picture.

What we measured — and where the numbers stop

We tested Ashtakavarga's predictive claims against our own validation set of birth charts with confirmed birth times and dated life events. Three separate claims, three results:

These are our own measurements, not published studies, and they test one specific question: does Ashtakavarga pick when something happens? It does not, on our data. What it does well is what the numbers were built for — ranking. It tells you, in a figure rather than an adjective, which parts of a chart carry support and which do not, and it grades a long transit far more concretely than "Saturn is difficult". That is a real contribution, and it is how we use it.

Using it in practice

1. Compute your SAV and note the three highest and three lowest signs. Convert them to houses using your ascendant.
2. Read the extremes, not the middle. A 34 and a 19 tell you something; 27 versus 29 does not.
3. Grade the slow transits. Find where Saturn and Jupiter are now, and look up those signs in Saturn's and Jupiter's own BAVs.
4. Combine with the running period. Bindus say how much support a matter has; the dasha says which matter is active now. Neither replaces the other.
5. Don't treat a low count as a verdict. It marks a harder area, not a closed one.

Our free Ashtakavarga calculator produces the SAV grid, all seven BAVs and today's transit grading in one pass, with no sign-up.

Common questions

How many bindus is a good Ashtakavarga score?

In the Sarvashtakavarga the 12 signs share exactly 337 points, so the average sign holds about 28. As a working convention, above 30 is well supported, 25 to 29 is ordinary, and below 25 — especially below 20 — marks an area that asks for more effort. In a single planet's Bhinnashtakavarga, where the maximum is 8, five or more is favourable and two or fewer is weak.

Why does Sarvashtakavarga always total 337?

Because the contributions are fixed. Each of the eight contributors gives its bindus in a set list of houses counted from itself, so each planet's own chart has a fixed total: Sun 48, Moon 49, Mars 39, Mercury 54, Jupiter 56, Venus 52 and Saturn 39. Those add to 337 in every chart ever cast. Only their distribution across the signs changes. If a calculator's SAV does not total 337, its tables are wrong.

What is the difference between SAV and BAV?

Bhinnashtakavarga (BAV) is one planet's own bindu chart, with a maximum of 8 points per sign. Sarvashtakavarga (SAV) is the sum of all seven planetary BAVs, distributing 337 points across the 12 signs. Use SAV to rank how well supported each house is, and a planet's own BAV to grade that planet's transit through a sign.

What are trikona and ekadhipatya shodhana?

The two classical reductions. Trikona shodhana (BPHS 67) works within the four triangles of signs, subtracting the lowest figure from all three — though no reduction is made when one of the three already holds nothing. Ekadhipatya shodhana (BPHS 68) adjusts for the five planets that rule two signs each, reducing the two figures against each other according to whether each sign is occupied or empty; the Sun and Moon are exempt, owning one sign each. Both feed longevity and finer predictive methods; everyday transit reading uses the unreduced figures.

Is Ashtakavarga the same as Shadbala?

No. Shadbala (BPHS 33) measures the strength of a planet from six sources — positional, directional, temporal, motional, natural and aspectual — expressed in rupas. Ashtakavarga measures how well supported a sign is, by counting bindus from the seven planets and the Ascendant. One grades the planet, the other grades the ground it stands on, and a chart can easily show a strong planet in a low-bindu sign.

Can Ashtakavarga predict when an event will happen?

Not in our testing. On our own validation set of charts with confirmed birth times and dated life events we checked three claims — natal SAV strength, sign-level transit grading and kaksha — and none picked the timing of events better than chance. What Ashtakavarga does well is rank: it shows which areas of a chart carry support and grades how a long transit sits, in numbers rather than adjectives.
