Nadi Dosha & Chart MatchingIn Vedic astrology marriage match is done primarily by matching the Nakshatra of a body and a girl. In North India this Nakshatra based matchis called Ashtakuta Guna Milap or 36 point match. Following eight (Ashta in Sanskrit) agreements are generally observed -

1. Varna (for Work compatibility, point allotted - 1)2. Vashya (for Dominance compatibility, point allotted - 2)3. Tara (for Destiny compatibility, point allotted - 3)4. Yoni (for Mentality compatibility, point allotted - 4)5. Graha Maitri (for General compatibility, point allotted - 5)6. Gana (for Guna-level compatibility, point allotted - 6)7. Bhakoota (for Love compatibility, point allotted - 7)8. Nadi (for Health compatibility, point allotted - 8)

The above compatibility is based on the Nakshatra occupied by Moon in proposed husband's and wife's chart. This test takes a deeper look at thecompatibility between two psychological, spiritual, physical and sub-conscious level. As you can see from the above table, Nadi has given themost points and hence regarded as the most important factor by astrologers. The Nadi disagreement between two is also called Nadi Dosha andgenerally regarded as the strict no for the marriage.

There are three different Nadis Adi (start), Madhya (middle) and Antya (end) and they represent "Prakriti" of an individual that is his/her bodyconstitution. As per Ayurveda there are three different Prakritis, vz Kaph, Vaat and Pita and Adi, Madhya and Antya Nadi are equivalent to thatonly. The exact Nakshatra based classification is as follows

Antya Nadi (Kapha) Madhya Nadi (Pitta) Adi Nadi (Vata)

Kritika Bharani Aswini

Rohini Mrigasira Ardra

Aslesha Pushya Punarvasu

Magha Poorvaphalguni Uttaraphalguni

Swati Chitra Hasta

Visakha Anuradha Jyehsta

Uttarashadha Poorvashadha Moola

Sravana Dhanshita Satabisha

Revati Uttarabhadrapada Poorvabhadrapada

Nadi Dosha exists if proposed husband and wife are having same Nadi. Scientifically speaking having same Prakriti means their offspring willbe physically weaker. If Nadis of proposed husband and wife are different it is only then marriage is recommended so they may have physicallystronger children.
