Kundli Matching: The 36 Gunas of Ashtakoota, Explained Test by Test
By Team Astro Acharya · 12 June 2026 · 10 min read
When two families in India sit down with horoscopes, the first number spoken aloud is the guna score — "28 out of 36", "saade attharah". That number comes from Ashtakoota Milan, the eight-fold matching of the partners' Moon positions. Here is what each test actually measures, in plain words, and what the score does not tell you.
The system in brief
Ashtakoota compares the janma nakshatra and Moon sign of both partners across eight kootas (tests). Each koota carries a weight, the weights total 36 gunas, and tradition reads the sum as a first gate:
| Score | Traditional verdict |
|---|---|
| 18–24 | Acceptable |
| 25–32 | Good |
| 33–36 | Excellent |
| Below 18 | Match needs deeper review |
The eight kootas, test by test
1. Varna (1 guna) — temperament class
Matches the partners' elemental "work-style" categories. The smallest weight; a mismatch costs little.
2. Vashya (2 gunas) — mutual influence
Measures natural amenability between the two Moon signs — who sways whom, and whether influence flows both ways.
3. Tara (3 gunas) — star compatibility
Counts the distance between the two birth stars in the 27-nakshatra wheel and checks whether each partner's star falls in an auspicious tara (group) from the other's. It speaks to mutual fortune and wellbeing.
4. Yoni (4 gunas) — instinctive compatibility
Each nakshatra carries an animal symbol; Yoni matches their instinctive, physical natures — same or friendly animals score high, hostile pairs (cat–rat, snake–mongoose) score zero. The classical proxy for physical and instinctual harmony.
5. Graha Maitri (5 gunas) — mental friendship
Compares the lords of the two Moon signs through the classical planetary friendship table. High scores mean the two minds default to understanding each other; low scores mean translation work.
6. Gana (6 gunas) — temperament group
Nakshatras divide into Deva (gentle), Manushya (balanced), and Rakshasa (intense) ganas. Like-with-like scores full; Deva–Rakshasa scores zero. This koota flags day-to-day temperamental friction.
7. Bhakoot (7 gunas) — the Moon-sign pair
Looks at the mutual house positions of the two Moon signs. Certain pairs — 6/8, 2/12, 5/9 — score zero as Bhakoot dosha, classically linked to health, finance, and family-line strains. Because the weight is 7, a Bhakoot failure drags the total hard.
8. Nadi (8 gunas) — constitution
The heaviest test. Nakshatras map to three nadis — Adi (Vata), Madhya (Pitta), Antya (Kapha). Same nadi = Nadi dosha = 0/8, traditionally read as risk to progeny and health of the couple. Different nadis score the full 8.
The doshas — and their cancellations
A low total is rarely the end of the discussion, because the tradition itself provides cancellations (dosha bhanga): Nadi dosha is classically neutralised when the partners share a Moon sign with different nakshatras (and in several other listed cases); Bhakoot dosha softens when the two sign lords are friends or the same planet. A matching report that stops at "Nadi dosha — reject" without checking cancellations is incomplete by the tradition's own rules.
Why 36/36 is not the whole story
Guna milan reads only the two Moons. It says nothing about:
- Mangal dosha — Mars placement, checked separately for both charts;
- The 7th house and its lord in each chart — the actual house of marriage;
- Venus and Jupiter — the karakas (significators) of relationship;
- The Navamsa — the marriage chart proper;
- Dasha timing — whether the marriage-giving periods of the two lives align.
This is why a 30-guna match can struggle while a 22-guna match thrives: the Moon-compatibility layer was never designed to carry the whole judgement alone. Treat Ashtakoota as the screening test and the full-chart analysis as the diagnosis.
Match your kundlis properly
Astro Acharya's free kundli matching computes both charts with Swiss-Ephemeris precision and reads the match the classical way — gunas first, then Mangal dosha, the 7th houses, and the Navamsas — explained in plain language rather than a bare score.
A good match is a door, not a destiny. The texts grade compatibility; the couple writes the marriage.
