Nadi is one of the important Kootas in matching making for the purpose of marriage in Vedic Astrology . Nadi Koota indicate whether the couple's ethereal vibrations will compliment each other or not. While matching horoscopes both of the partners should not have same nadis. When they have same nadis they have nadi dosha and this is not considered good for health and progeny point of view. It can cause health problems, ailments, affect life and longevity.
There is no cancellation of nadi dosha. But if the partners have same constellation but born in the different quadrant of that constellation than there is possibility of marriage.
