The framework
Two Moons, eight kootas, out of 36
Ashtakoota matches the two natal MOONS across eight kootas, each worth a fixed maximum: Varna 1, Vashya 2, Tara 3, Yoni 4, Graha-maitri 5, Gana 6, Bhakoota 7, Nadi 8 — totalling 36. Varna, Vashya, and Gana are scored directionally (groom's group against bride's); the rest are symmetric. It is a MOON-to-Moon compatibility screen, nothing wider.
Varna 1 · Vashya 2 · Tara 3 · Yoni 4 · Graha-maitri 5 · Gana 6 · Bhakoota 7 · Nadi 8 = 36.
Reference tables
The three you'll compute with most
BHAKOOTA (mutual sign distance): a dosha at 2/12 (dwirdwadasha), 5/9 (navapanchama), or 6/8 (shadashtaka); every other distance scores the full 7. NADI cycles across the 27 nakshatras as Adi, Madhya, Antya, Antya, Madhya, Adi — repeating; the SAME nadi is nadi dosha (0). GANA: Deva, Manushya, or Rakshasa per nakshatra — best matched like-with-like, worst Manushya-groom with Rakshasa-bride (0).
Rohini is Manushya gana and Antya nadi; Hasta is Deva gana and Adi nadi.

Rohini/Taurus × Hasta/Virgo — first four kootas
VARNA: both signs are earth (Vaishya); the groom is not below the bride, so 1/1. VASHYA: Taurus is Chatushpada, Virgo is Manava — the table gives 1/2. TARA: counting nakshatra-to-nakshatra both ways lands on auspicious taras, so 3/3. YONI: Rohini's animal is Serpent, Hasta's is Buffalo — a low-affinity pair on the matrix, 1/4. Running subtotal: 6.
Varna 1 + Vashya 1 + Tara 3 + Yoni 1 = 6 of a possible 10 so far.

The last four kootas, and the total
GRAHA-MAITRI: Taurus's lord Venus and Virgo's lord Mercury are mutual friends — a full 5/5. GANA: Manushya groom with Deva bride scores 5/6. BHAKOOTA: Taurus to Virgo is the 5th (and Virgo to Taurus the 9th) — a 5/9 navapanchama, so a DOSHA, 0/7. NADI: Antya versus Adi — different, so clear, 8/8. Total: 6 + 5 + 5 + 0 + 8 = 24/36, with a Bhakoota dosha and Nadi clear.
Graha-maitri 5 + Gana 5 + Bhakoota 0 + Nadi 8 = 18; plus the earlier 6 = 24/36.
The thresholds
Read the total against working bands: below 18 is generally not recommended; 18–24 is average and acceptable; 24–32 is good; above 32 is excellent. Our couple's 24 sits right at the good boundary — a solid Moon-match. But a total near a threshold is a prompt to look deeper, never a pass/fail switch on a marriage.
24/36 is a genuinely good koota score — and still only a partial picture.
The Nadi override
Not all kootas weigh the same when they FAIL. A Nadi dosha (same nadi, 0/8) is the classically overriding defect — traditionally serious enough to question even a high total, on grounds of genetic-symbolism and progeny. Bhakoota (0/7) is the next-weightiest. Our couple carries the Bhakoota dosha but NOT the Nadi one, which is why 24 reads as a workable match rather than a vetoed one.
Same score, two stories: a 24 with Nadi dosha is shakier than a 24 with only Bhakoota missing.
What the number does NOT measure
The essential honesty. Ashtakoota reads Moon-to-Moon ONLY. It says nothing about either chart's strength, the dashas they're running, their 7th houses, the Kuja dosha (a separate check, n97), or their emotional maturity, love, and choice. A high score is not a happy marriage promised, nor a low score a doom — it is one witness among many.
Two 30-scoring Moons can belong to two afflicted 7th houses running hard dashas — the koota total never saw them.
The one idea to keep
Score it, bound it, never let it judge
Hand-score the eight kootas to a total out of 36, read it against the 18/24/32 bands, respect the Nadi override, and then say plainly what it cannot see — chart strength, dashas, the 7th houses, Kuja dosha, love, and choice. The number is a Moon-compatibility screen, not a verdict on two lives.
