Where is the best place to perform Narayan Bali?

Trimbakeshwar in Nashik is the most scripturally authoritative location for Nagbali specifically, as designated by the Dharma Sindhu and Skanda Purana. Prayagraj at the Triveni Sangam is equally authoritative for the broader Narayan Bali ritual and is preferred for families in North India given the power of the Ganga-Yamuna-Saraswati confluence. Haridwar and Gaya are also authoritative locations. The key is ensuring pandits at the chosen site are fully trained in the complete ritual sequence including all five suktas.
