Your Birth star gets determined as per the date and time of your birth. Each birth star is divided into three different nadis: 1. Aadi or First Nadi 2. Madhya or Middle Nadi 3. Antar or Last Nadi To ensure that there’s no disruption in a marriage, and the relationship stays intact, the couple must be born in different nadis. If that’s not the case, it leads to Nadi Dosha and difficulties in a marital relationship. One possible Nadi dosh remedy many astrologers suggest doing is – recital of the Mahamrityunjaya Mantra, the prescribed number of times and donating cloth, some grains, etc. to your local priest.
