What is Kundli Matching?
Kundli Matching (Kundli Milan) is the traditional comparison of two birth charts before a marriage. In most Indian families it begins with Guna Milan, the method called Ashtakoota: eight tests, the kootas, which compare the Moon of one partner with the Moon of the other.
Each koota is worth a fixed number of points, from 1 for Varna to 8 for Nadi, for 36 points in all. The total is the Guna Milan score. Tradition treats 18 as the minimum for a match to be considered, and looks closely at two doshas, Nadi and Bhakoot, whatever the total.
Guna Milan is a starting point, not a verdict. It compares only the two Moons, the mind and the emotions in Jyotisha. An astrologer also reads both full charts: the seventh house of marriage, Venus, Jupiter, the Manglik placement and the periods each person is running.
