नाड़ी दोष: विवाह अनुकूलता का निर्णायक तत्त्व

Nadi Dosha Within the Ashtakoot Milan Compatibility System

The Ashtakoot Milan system — the classical eight-factor Vedic marriage compatibility framework — assigns a total of 36 Guna points across eight categories of comparison: Varna (1 point), Vasya (2), Tara (3), Yoni (4), Graha Maitri (5), Gana (6), Bhakoot (7), and Nadi (8). Nadi carries the maximum weight — 8 points — making it the single most significant factor in classical Ashtakoot analysis. The Nadi category tests the Ayurvedic constitutional compatibility (Prakriti) of the prospective partners as revealed through the Moon's nakshatra position. All 27 nakshatras are divided into three Nadi groups of nine nakshatras each: Adi Nadi (associated with Vata constitution), Madhya Nadi (associated with Pitta constitution), and Antya Nadi (associated with Kapha constitution). Nadi Dosha arises when both partners' Moon nakshatras fall in the same Nadi group — both Adi, both Madhya, or both Antya. The Ayurvedic logic is grounded in the principle of constitutional complementarity: in Prakriti science, like constitutions amplify each other's imbalances rather than creating equilibrium. Two Vata individuals in sustained intimate union intensify each other's Vata tendencies — anxiety, dryness, inconsistency — rather than moderating them. Two Pitta individuals together amplify heat, competition, and inflammatory tendencies. Constitutional complementarity requires difference, not sameness, in the Nadi domain, making same-Nadi matching the most serious of the eight compatibility deficits.
