Why is Prayagraj particularly important for Sarva Pitru Amavasya Shraddha?

Prayagraj is uniquely suited for Sarva Pitru Amavasya because of the Triveni Sangam — the confluence of Ganga, Yamuna, and the mystical Saraswati. Scriptures state that offerings made at a Sangam (river confluence) carry seven times the merit of offerings made at a single river. Additionally, Prayagraj is one of the few tirthas where the Pitri Sukta mantra resonates through all three rivers simultaneously, reaching ancestors in all three loka realms. Maha Kumbh Mela has been held at Prayagraj precisely because of this cosmic confluence. Performing Sarva Pitru Amavasya Shraddha at Arail Ghat or Sangam Bhata during the Aparahna Kaal is considered one of the most spiritually powerful acts a descendant can perform.
