Which location is most auspicious for Purnima Shradh?

The most auspicious locations are the Triveni Sangam at Prayagraj, the ghats at Varanasi (especially Manikarnika and Pishachmochan), and Vishnupad Gaya. Among these, the Triveni Sangam holds special status because the confluence of three sacred rivers — Ganga, Yamuna, and the invisible Saraswati — creates an energy field of exceptional spiritual potency.
