Ashtakoota Guna Milan: The 36-Point Kundali Matching System
Eight classical tests, thirty-six points, one traditional screen — not a verdict on a marriage.
The short answer
Ashtakoota guna milan compares two people's Moon sign and nakshatra across eight kootas worth 1, 2, 3, 4, 5, 6, 7 and 8 points (36 total). Eighteen is the traditional passing mark, but classical practice also checks specific doshas and their cancellations before reading the total as anything more than an opening conversation.
What ashtakoota actually compares
Ashtakoota (ashta meaning eight, koota meaning a test or grouping) is the classical Vedic system for screening a proposed marriage match, still widely used across India today. It does not look at the whole of either birth chart. It looks at exactly one placement in each: the Moon's sign and nakshatra — the position classical texts treat as the seat of mind and temperament, and therefore the most direct proxy for how two people will get along day to day.
Kootaone of eight compatibility tests that compare two people's Moon positions, each worth a different maximum score
Each of the eight kootas asks a narrower question — temperament, instinct, friendship between planetary lords, and so on — and each carries a different maximum, from 1 point up to 8. The weights are not arbitrary: they ascend toward the tests classical astrologers considered deepest, so a single low-scoring early koota matters far less than a shared problem in the last two.
The eight kootas and their exact point values
Here is what each koota measures and how many points it can contribute, adding to a maximum of 36:
| # | Koota | Max points | What it reads |
|---|---|---|---|
| 1 | Varna | 1 | Temperamental class — a basic seniority grouping of the two Moon signs |
| 2 | Vashya | 2 | Mutual sway — which nature tends to influence which |
| 3 | Tara | 3 | Birth-star distance, counted both ways, read for wellbeing |
| 4 | Yoni | 4 | Instinctive and physical nature, via each nakshatra's symbolic animal |
| 5 | Graha Maitri | 5 | Friendship between the planetary lords of the two Moon signs |
| 6 | Gana | 6 | Temperament group — deva, manushya, or rakshasa nature |
| 7 | Bhakoot | 7 | Distance between the two Moon signs, read for prosperity and family harmony |
| 8 | Nadi | 8 | Constitutional channel — the single heaviest-weighted koota |
The eight kootas, one by one
Varna: 1 point
Varna sorts each Moon sign into one of four classes — Brahmin, Kshatriya, Vaishya, or Shudra — a temperamental ranking rather than a social one in this context. Classical practice checks the point in one direction only: it is granted when the first chart's class ranks equal to or senior to the second's, and withheld (not reversed) otherwise. It is the lightest koota in the system, a coarse first filter rather than a real signal on its own.
Vashya: 2 points
Vashya groups the twelve signs into five natures — quadruped, human, water-dwelling, wild, and insect — and scores how much one nature can be expected to sway the other. Same group scores the full 2. A few pairings are read as one nature having little natural pull on the other and score 0; most graded pairings fall at 0.5 or 1. Sagittarius and Capricorn are treated as dual-natured in classical texts; most matching software, including this app, resolves them with a fixed whole-sign convention rather than splitting by degree.
Tara: 3 points
Tara counts the distance from one person's birth star to the other's, in both directions, around the 27-nakshatra wheel. Each count is reduced to a position 1 through 9 in a repeating cycle; positions 3, 5, and 7 in that cycle are the "testing" taras and score 0 for that direction, the rest score 1.5. Because it is checked both ways, the maximum is 1.5 + 1.5 = 3.
Yoni: 4 points
Every nakshatra carries a symbolic animal — horse, elephant, serpent, cow, and so on — representing an instinctive, almost physical layer of nature. Identical yoni scores the full 4. A short list of classical enemy pairs (horse–buffalo, elephant–lion, cat–rat, cow–tiger, and a few others) scores 0. Every other pairing sits on a graded friendliness table between 1 and 3.
Graha Maitri: 5 points
This koota looks past the Moon sign itself to that sign's ruling planet, and asks whether the two rulers are classical friends. Planetary friendship in Vedic astrology is not always mutual — Mars counts Mercury an enemy, but Mercury does not return the feeling — so this koota checks both directions and scores the combination: 5 when both count each other a friend (or it's the same planet ruling both signs), 4 when one is friendly and the other neutral, 3 when both are neutral, dropping to 1 or 0.5 where one side is openly hostile.
Gana: 6 points
Gana sorts all 27 nakshatras into three temperament groups: deva (refined), manushya (ordinary human), and rakshasa (intense, driven). Same gana scores the full 6. Deva paired with manushya scores 5 — a mild, workable difference. Deva paired with rakshasa scores only 1, and manushya paired with rakshasa scores 0 — the combination classical texts flag as the most temperamentally friction-prone of the three pairings.
Bhakoot: 7 points, and Bhakoot dosha
Bhakoot measures the raw sign distance between the two Moons — how many signs apart they sit, counted both ways. Most distances score the full 7 outright. Three specific distance pairs are withheld entirely and score 0: signs 2 and 12 apart, 5 and 9 apart, and 6 and 8 apart. When a match falls into one of these, it is called Bhakoot dosha — traditionally read as a caution around shared prosperity and family harmony between the two households, not between the two people's affection for each other.
Nadi: 8 points, and Nadi dosha
Nadi groups the 27 nakshatras into three constitutional channels — adi, madhya, and antya — an idea classical texts tie to physiological and temperamental compatibility, and by extension to healthy offspring. It is scored as a straight pass/fail: different nadi scores the full 8, and identical nadi scores 0 outright — the only koota the tradition withholds completely rather than grading. Because it also carries the single heaviest weight of the eight, a same-nadi pairing is usually the deciding factor in a low total.
Nadi dosha and the idea of cancellation
A same-nadi pairing, called Nadi dosha, is the most feared result in popular ashtakoota discussion — but classical texts have always paired it with conditions under which the dosha is considered cancelled and no longer weighs against the match. Traditionally cited cancellations include the two Moons sharing the same nakshatra but different padas, sitting in different signs entirely despite the shared nadi, or one of several other configurations named across different texts. Traditions genuinely disagree on exactly which conditions count, and on how many of them apply at once — this app reports the plain nadi result and leaves cancellation judgment to a knowledgeable reader rather than asserting one convention as final.
What the total traditionally means
Summing all eight kootas gives a score out of 36. Eighteen is the classical passing threshold, but the bands below are read as degrees, not a single cliff:
- 28 to 36 — traditionally read as an excellent match in this system
- 24 to 27 — traditionally read as a very good match in this system
- 18 to 23 — traditionally read as an average, workable match in this system
- Below 18 — traditionally read as a below-average score in this system, prompting a closer look at which specific kootas failed and why
A low score is a prompt to look closer, not a verdict. Classical practice never stopped at the sum: it asks which kootas failed, whether Nadi or Bhakoot dosha is present and whether a recognised cancellation applies, and it weighs the rest of both birth charts — dashas, house lords, and general strength — alongside the number. Plenty of long, happy marriages sit below eighteen; the score is a traditional opening conversation within this system, never a prediction that a marriage will or will not succeed.
Common mistakes and where traditions differ
The most common misreading is treating 36 as a percentage of "how compatible" two people are, or worse, as a prediction of a marriage's outcome. It is neither. It is a fixed-format screen of one placement — the Moon — designed centuries ago to standardize an otherwise very subjective judgment, and it was always meant to be one input among several, alongside Manglik status, the strength of both charts overall, and a family's own values.
A second common mistake is treating Nadi or Bhakoot dosha as automatically disqualifying, without checking for a cancellation, and without asking how the rest of the two charts look. Classical practice was always more nuanced than the pass/fail headline suggests, and most traditional astrologers historically read a single dosha in context rather than in isolation.
Where practitioners genuinely differ: the exact Yoni and Vashya grading tables at their edges, whether Sagittarius and Capricorn's dual nature should be split by degree rather than treated as one whole sign, and — most consequentially — exactly which conditions cancel Nadi dosha. None of these disagreements are errors; they are live differences between schools and regional practices, and worth naming rather than smoothing over with false precision.
Questions people ask
What is a good ashtakoota score for marriage?
Eighteen out of 36 is the traditional passing mark, and 24 or above is traditionally read as a very good match. But classical practice never reads the number alone — it checks for Nadi and Bhakoot dosha specifically and looks at the rest of both charts. A score below 18 is a prompt to look closer, not a verdict against the match.
What is Nadi dosha and can it be cancelled?
Nadi dosha occurs when both people's birth stars fall in the same one of the three nadis (adi, madhya, antya), scoring 0 of the 8 available points — the only koota scored as a strict pass/fail. Classical texts describe several traditional cancellation conditions, such as the same nakshatra with different padas, though traditions differ on exactly which conditions apply.
What is Bhakoot dosha?
Bhakoot dosha occurs when the two Moon signs sit 2/12, 5/9, or 6/8 signs apart, scoring 0 of the 7 Bhakoot points. It is traditionally associated with concerns around shared prosperity and family harmony rather than the couple's own compatibility, and like Nadi dosha, classical practice checks for recognised cancellations before weighing it heavily.
Why does ashtakoota only use the Moon sign?
Classical Vedic astrology treats the Moon as the seat of mind and emotional temperament, making it the most direct single placement for judging day-to-day compatibility. Ashtakoota was designed as a fast, standardised screen using that one placement — not as a substitute for reading the rest of both charts.
Can two people marry with a low guna milan score?
Yes. A low score means several of the eight tests disagree, which classical practice reads as worth a closer look at doshas and the wider charts — not as a rule against marriage. Many traditions and families treat 18 as a soft minimum rather than a hard cutoff, and plenty of long marriages exist below it.
Is 36/36 a perfect ashtakoota match?
A 36 means every one of the eight tests scored its maximum on this one placement — the Moon. It is a strong result within this specific system, but ashtakoota still says nothing about the Sun signs, ascendants, or the rest of either birth chart, which classical practice would still want to check separately.
Do all matching platforms score ashtakoota the same way?
The core structure — eight kootas summing to 36 — is standard, and this app follows the widely used Parashari point tables. But a few regional traditions vary at the edges, particularly in the Yoni and Vashya grids, so small point differences between platforms on the same two charts are not unusual.
