Guna Milan: The 36-Point Ashtakoota Kundli Matching System

Guna Milan (गुण मिलन), the Ashtakoota (“eight-fold”) system, is the most familiar method of matching two charts for marriage in North Indian tradition. It compares the Moon’s Nakshatra and sign of the prospective partners across eight factors (kootas) and produces a score out of 36 points. It is quick, structured, and widely used — and it is best understood as a first screen, not the whole compatibility reading.

This guide walks through all eight kootas, what the score means, and the two doshas that deserve the most care.

The eight kootas and their points

Each koota tests a different layer of harmony and carries a different maximum score. They add up to 36:

Koota	Points	What it tests
Varna	1	Spiritual/temperamental compatibility (work-nature)
Vashya	2	Mutual attraction and control in the relationship
Tara (Dina)	3	Health and wellbeing (birth-star harmony)
Yoni	4	Physical and sexual compatibility (animal symbol)
Graha Maitri	5	Mental and psychological friendship (sign-lords)
Gana	6	Temperament — Deva, Manushya or Rakshasa nature
Bhakoot	7	Family welfare, prosperity, emotional bond (Moon signs)
Nadi	8	Health and progeny (constitution / Ayurvedic Nadi)
Total	36

The scores are derived entirely from each person’s Janma Nakshatra (Moon’s lunar mansion) and Janma Rashi (Moon sign) — which is exactly why an accurate Moon position, and therefore an accurate birth time, matters.

What the score means

The convention most astrologers use:

• Below 18 — generally considered an unfavourable match; reconsider or examine closely.
• 18–24 — acceptable; marriage is permitted.
• 25–32 — a very good match.
• 32–36 — excellent.

A perfect 36 is rare and not actually required. Many lasting marriages sit comfortably in the low-to-mid 20s. The number is a starting filter, not a measure of love.

The two doshas that matter most

Two kootas carry the heaviest weight because a zero in them raises specific classical concerns:

Nadi dosha (Nadi koota, 8 points). Nadi reflects constitution (Aadi/Vata, Madhya/Pitta, Antya/Kapha). If both partners share the same Nadi, the koota scores 0, traditionally linked to concerns about health and progeny. It is the most weighted single factor — and it has well-known cancellations: same Nakshatra but different pada, the same sign with different Nakshatras in some readings, and strong benefic support are all checked before the dosha is treated as serious.

Bhakoot dosha (Bhakoot koota, 7 points). Based on the distance between the two Moon signs. Certain relationships (notably 6–8 and 2–12 between the signs) score 0 and are flagged for prosperity and emotional friction. Bhakoot dosha is also cancelled under classical rules — for example when the sign-lords are friends or the same planet rules both signs.

The lesson is the same as with Mangal Dosha: a zero in a koota is a prompt to investigate cancellations, not an automatic rejection.

Where Guna Milan stops — and what completes it

Guna Milan only ever compares the Moon. It says nothing directly about the house of marriage itself. A complete compatibility reading goes further:

• The 7th house and its lord in each chart, and the natural karaka Venus.
• Mangal Dosha in both charts and whether it is cancelled or mutual.
• The Navamsa (D9) — the divisional chart of marriage and dharma — for both partners.
• The Dashas each person is running, since timing shapes how a marriage begins and matures.

A high Ashtakoota score on a chart with a damaged 7th house and an uncancelled marriage affliction is not the clean signal the number suggests. Conversely, a moderate score with strong 7th-house and Navamsa support can be an excellent match.

A note on the South Indian method

South Indian tradition uses a different framework — 10 Porutham (Dina, Gana, Mahendra, Stree-Dheerga, Yoni, Rasi, Rajju, Vedha, Vasya, Nadi) — rather than the 36-point Ashtakoota. The two systems overlap in spirit but differ in calculation, and a thorough match can be read both ways.

Match two charts properly

Acharya Jyotish computes the full 36-point Ashtakoota Guna Milan — every koota scored and explained — alongside the South Indian 10 Porutham, so you can see the match through both traditions, with the dosha cancellations checked rather than assumed.

Match two Kundlis free to get the koota-by-koota breakdown, then read Mangal Dosha to understand the marriage factor it sits beside — or start with What is a Kundli if you are new to the chart.
