What is Nadi dosha?
Nadi dosha arises in Gun Milan when both partners share the same Nadi (Aadi, Madhya or Antya), scoring 0 of the 8 points for the Nadi koota — the highest-weighted factor.
It is traditionally taken seriously for health and progeny, but several cancellations (Nadi dosha parihara) exist — for example when the couple share a Moon sign but different nakshatras, or the same nakshatra but different padas.
