The adage seems truer when two people, as different as chalk and cheese, end up spending a lifetime with one another — and happily so. This is also why Hindu astrology lays emphasis on matching of their respective Kundalis before a couple ties the knot. Kundali matching is based on the age-old Ashtakuta method and is done to determine the compatibility of two people. In Hindu tradition, Kundali matching is a key ritual ahead of solemnizing a marriage. It is the process of matching horoscopes birth-charts of the bride and the groom to determine whether their stars are in harmony for a successful and happy marriage. Many factors come into play to determine the same, including the number of Gunas.
