Kundli Matching โ Marriage Compatibility Analysis
In Vedic tradition, Kundli matching (Guna Milan or Melapaka) is the structured way to check whether two charts will support a stable, harmonious marriage. The most widely used method is the Ashta Koota system from classical texts like Brihat Parashara Hora Shastra and Muhurta Chintamani โ eight separate compatibility factors, each scored independently, then summed into a single Guna score out of 36.
The Ashta Koota score is a screening filter, not a final verdict. It captures temperament markers, biological compatibility, and family-life factors. A complete assessment also looks at Mars positions in both charts (Manglik dosha), 7th house condition, Venus and Jupiter strength, dasha alignment at the time of marriage, and longevity factors. This tool computes the full Ashta Koota and provides flags for the additional factors that a knowledgeable practitioner would always check.
The Ashta Koota โ 8 Compatibility Factors (36 points total)
Varna
1 ptSpiritual development and ego compatibility. Based on Moon sign category โ Brahmin, Kshatriya, Vaishya, Shudra. Indicates whether partners can grow together at a similar pace.
Vasya
2 ptMutual influence and dominance. Determined by Moon sign group โ quadruped, biped, aquatic, jungle, or insect. Reflects who naturally leads in the relationship dynamic.
Tara
3 ptBirth star compatibility โ emotional and physical wellbeing. Counted from one Nakshatra to another in groups of 9. Shows how the relationship affects each partner's stability.
Yoni
4 ptSexual and instinctive compatibility. Each Nakshatra has an animal symbol (14 yonis total). Strong Yoni match often indicates physical comfort; hostile Yonis can mean friction.
Graha Maitri
5 ptFriendship between Moon sign lords. The most important psychological compatibility factor โ whether the two minds naturally understand and respect each other.
Gana
6 ptTemperamental category โ Deva (divine), Manushya (human), or Rakshasa (demonic). Same Gana matches favour harmony; Deva-Rakshasa pairings often need conscious effort.
Bhakoot
7 ptMoon sign relationship for finances, family welfare, and longevity. Certain count distances (6-8, 2-12) are considered Doshas requiring careful evaluation and possible cancellation.
Nadi
8 ptHealth, genetic, and progeny compatibility. Three categories โ Adi, Madhya, Antya โ derived from Nakshatra. Same Nadi is traditionally avoided unless cancellation conditions apply.
Score Interpretation Bands
Generally not recommended. Significant compatibility gaps that need detailed chart-level investigation and corrective context before considering further.
Workable with stronger chart support. Other factors โ 7th house, Venus, Jupiter โ must clearly compensate for the lower Guna score.
Considered stable in practice. Most traditional astrologers regard this as a confident match, subject to standard chart review.
Strong compatibility on Guna factors. Still requires full chart review for Mangal Dosha, longevity, and dasha alignment before finalizing.
Beyond the Score โ What Else Matters
- Manglik (Mangal Dosha): Mars in the 1st, 4th, 7th, 8th, or 12th house can stress marriage. Cancellation rules apply when both partners are Manglik or specific aspects relieve the dosha.
- 7th house and 7th lord: The quality, dignity, and aspects of each partner's 7th house and its lord predict long-term marriage harmony better than any score alone.
- Venus (men) and Jupiter (women): Venus indicates spouse for men; Jupiter indicates husband for women. Their condition in each chart explains how the partner experience unfolds in practice.
- Dasha at marriage time: Even compatible charts can face stress if marriage starts in a conflicting Dasha period. Timing alignment improves the first few years dramatically.
Tip: Use the score to ask better questions, not to make instant decisions. Even a high Guna score deserves full chart review; even a low score may have valid cancellation conditions. Read the full Guna Milan score guide โ
