When two families come together to discuss a marriage alliance, the first thing a traditional Hindu family typically does is compare the horoscopes. At the heart of this process is Ashta Koota matching — an ancient Vedic system that evaluates marriage compatibility across eight different parameters.
The word “Ashta” means eight, and “Koota” means group or point. Together, Ashta Koota matching is a structured scoring system that assigns points to eight areas of compatibility between two birth charts. The maximum possible score is 36 Gunas, and the system is designed to assess whether two individuals are well-matched for a long, harmonious marriage.
What is the Ashta Koota System?
Ashta Koota matching is based on the Nakshatra (birth star) of both the bride and groom. The Nakshatra is determined from the Moon’s position at the time of birth. This is why kundali matching for marriage is sometimes called Nakshatra porutham in South India. Each of the eight kootas tests a specific dimension of compatibility — from basic temperament to sexual harmony, financial stability, and health of children.
The 8 Kootas — Complete Breakdown
| # | Koota Name | Max Points | What It Measures |
|---|---|---|---|
| 1 | Varna | 1 | Spiritual compatibility and ego levels |
| 2 | Vashya | 2 | Mutual control, attraction, and dominance |
| 3 | Tara | 3 | Destiny compatibility and long-term health/fortune |
| 4 | Yoni | 4 | Physical and sexual compatibility |
| 5 | Graha Maitri | 5 | Mental compatibility and friendship between Moon signs |
| 6 | Gana | 6 | Temperament and nature (Deva, Manushya, or Rakshasa) |
| 7 | Bhakut | 7 | Emotional compatibility and family well-being |
| 8 | Nadi | 8 | Health compatibility and progeny (childbearing) |
| Total | 36 |
1. Varna (1 point)
Varna represents the spiritual or psychological nature of a person based on their Nakshatra. There are four Varna types — Brahmin, Kshatriya, Vaishya, and Shudra — which in this context represent levels of spiritual development. The groom’s Varna should ideally be equal to or higher than the bride’s for full points.
2. Vashya (2 points)
Vashya tests the natural affinity and mutual influence between two partners. The 12 Rashis are grouped into five categories: Manav, Chatushpad, Jalachara, Vanchar, and Keeta. Full points (2) are scored when the signs have strong mutual control; partial points (1) for one-sided influence; 0 for no connection.
3. Tara (3 points)
Tara (or Dina) koota examines the relationship between the Nakshatras in terms of long-term fortune and health. The Nakshatra of the groom is counted from the bride’s Nakshatra, and the result (divided by 9) determines the Tara score. Odd remainders are auspicious; even ones inauspicious.
4. Yoni (4 points)
Yoni koota assesses physical and sexual compatibility. Each Nakshatra is assigned a symbolic animal, and compatibility is determined by how these animals relate in nature. Friendly animals score 4 points; hostile pairings score 0–1.
5. Graha Maitri (5 points)
This koota measures the compatibility of the ruling planets (lords) of the Moon signs of both partners. If the two planetary lords are natural friends, the couple is likely to have a harmonious mental connection. Friendly lord pairs score 5 points; enemy pairs score 0–1. Graha Maitri is considered one of the most important kootas for a successful long-term marriage.
6. Gana (6 points)
Gana koota classifies each Nakshatra into one of three categories — Deva (divine), Manushya (human), and Rakshasa (fierce). Both partners in the same Gana score 6 points. Deva and Rakshasa is generally considered an incompatible match and scores 0.
7. Bhakut (7 points)
Bhakut is one of the highest-weighted kootas at 7 points. It tests emotional and relational compatibility between the Moon signs. Certain combinations — like 6-8 (Shad-Ashtaka) or 2-12 positions — are considered inauspicious and may indicate emotional distance, financial troubles, or conflict.
8. Nadi (8 points)
Nadi carries the maximum weight — 8 points — making it the most important koota. Each Nakshatra belongs to one of three Nadis: Aadi (Vata), Madhya (Pitta), or Antya (Kapha). If both partners belong to the same Nadi, it is called Nadi Dosha and scores 0 points. Different Nadis score the full 8 points.
What Does Your Total Guna Score Mean?
| Score Range | Interpretation | Recommendation |
|---|---|---|
| 0 – 17 | Poor compatibility | Marriage generally not recommended without deeper analysis |
| 18 – 24 | Acceptable compatibility | Proceed with caution; check for Doshas |
| 25 – 32 | Good compatibility | Recommended; strong foundation for marriage |
| 33 – 36 | Excellent compatibility | Ideal match; very auspicious |
