Kundli Milan Explained: How 36-Gun (Ashtakoota) Matching Works

Gun milan is the systematic compatibility scoring method of Vedic astrology, rooted in the Ashtakoota (eight-factor) framework. Each factor — called a koota — measures a specific dimension of two people's potential for harmony, drawing information from their birth nakshatras and moon signs. The maximum total is 36 points; the method originates in classical texts including Brihat Parashara Hora Shastra and Muhurta Chintamani.

• Varna (1 pt): Spiritual temperament and social harmony — Brahmin, Kshatriya, Vaishya, Shudra classification based on nakshatra. The bride's varna should not exceed the groom's for full points.
• Vashya (2 pts): Mutual attraction, influence, and loyalty dynamics between the two moon signs.
• Tara (3 pts): Star-based auspiciousness — the birth star of the groom counted from the bride's and vice versa; certain counts are auspicious, others neutral or inauspicious.
• Yoni (4 pts): Each nakshatra is assigned an animal symbol (14 pairs); points based on animal compatibility ranging from 4 (same yoni) to 0 (enemy yoni).
• Graha Maitri (5 pts): Mental wavelength — assessed by the friendship between the lords of both moon signs.
• Gana (6 pts): Basic nature — Deva (divine), Manushya (human), or Rakshasa (fierce). Same gana = full 6 pts; Deva–Manushya = 5 pts; incompatible combinations = 0 pts.
• Bhakoot (7 pts): Moon sign relationship — full 7 for harmonious positions; 0 for 2/12, 5/9, or 6/8 configurations (unless cancelled by Graha Maitri).
• Nadi (8 pts): Constitutional harmony — different nadis score full 8; same nadi scores 0 (unless cancelled).

ShubhLekha computes all eight kootas using precise nakshatra positions, applies classical cancellation rules for Nadi and Bhakoot doshas, and presents both the raw score and the interpreted score with dosha status clearly distinguished. The report also flags any major strengths or concerns in individual kootas rather than relying solely on the aggregate number.
