Why Kundli matching is done

In the Vedic tradition marriage is the most important relationship of a lifetime. It is seen as a karmic partnership that shapes both personal happiness and spiritual growth. Kundli matching, also called Horoscope Matching, Gun Milan or Ashtakoota matching, compares two birth charts to judge compatibility across eight areas of life.

Ashtakoota is the most widely used framework for this, and experienced astrologers go well beyond it. They look at the 7th house, Venus, Mangal Dosha, the Navamsha chart and Dasha compatibility. The 36-point score is where the reading starts. It is only a part of the full picture.

The 8 factors of Ashtakoota

Ashtakoota means "eight indicators". Each factor looks at a different side of compatibility and carries its own maximum points, and the total is 36.

  • Varna (1 point): spiritual compatibility and ego harmony, based on the fourfold grouping of Moon signs. A mismatch suggests minor friction in how the two of you approach spiritual life day to day.
  • Vashya (2 points): mutual influence and the pull or dominance between partners. It shows who tends to lead and whether both are comfortable with that balance.
  • Tara (3 points): birth star compatibility, worked out by counting Nakshatra positions from each person's Janma Nakshatra. It points to the general health and wellbeing of the relationship.
  • Yoni (4 points): physical and sexual compatibility. Each Nakshatra has an animal symbol (Yoni). Compatible Yonis suggest natural physical harmony, and incompatible ones suggest an area that needs conscious effort.
  • Graha Maitri (5 points): the friendship between the ruling planets of the two Moon signs. It reflects mental harmony, mutual respect and whether a deep friendship can last within the marriage.
  • Gana (6 points): compatibility of temperament. Each Nakshatra belongs to one of three Ganas: Deva (divine), Manava (human) or Rakshasa (fierce). The best match is the same Gana, or Ganas that suit each other.
  • Bhakoot (7 points): the relationship between the two Moon signs, judged by the count between them. It carries a lot of weight for emotional harmony and marital happiness.
  • Nadi (8 points): the factor with the highest weight. Each Nakshatra belongs to one of three Nadis: Aadi (Vata), Madhya (Pitta) or Antya (Kapha). The two partners should have different Nadis. A shared Nadi is called Nadi Dosha, and it is treated with caution in the tradition. The tradition also lists cancellations that vary between schools, so it calls for an astrologer's judgement, not an automatic verdict.

How to read the score

The maximum is 36 points. The usual guidelines are: below 18 is not advised without further study, 18 to 24 is acceptable if both sides bring effort and awareness, 25 to 32 is good and a solid base for a lasting partnership, and above 32 is excellent. These ranges are guidelines and carry no final verdict. A couple scoring 28 with a Nadi Dosha may have a harder time than a couple scoring 22 with no significant doshas. The score has to be read together with the full chart analysis.

What astrologers look at beyond the score

Experienced astrologers check several things that sit outside the 36-point score. The first is the strength of the 7th house in each chart: its lord, the planets in it and its overall condition are the first things looked at for marriage. Venus is the natural significator of relationships for men and Jupiter for women, so their placement and strength matter too. The Navamsha (D9 chart) is the divisional chart that speaks most directly about marriage, and a strong Navamsha is read as support for a marriage that deepens with time.

Then there is Mangal Dosha, the placement of Mars in the 1st, 2nd, 4th, 7th, 8th or 12th house. This is the commonly used list, though schools differ on the houses, and it can be judged from the Lagna, the Moon and Venus. The tradition describes several cancellations, including both partners having Mangal Dosha, so it is judged with the whole chart and never from one rule. Finally, an astrologer compares the Dashas. If both partners are in a difficult Dasha at once, or both are in Sade Sati at the same time, the marriage meets more outside pressure than when their cycles are staggered.
