Is Asthi Visarjan at Prayagraj more significant than at other holy places?

According to Hindu scriptures, particularly the Prayaga Mahatmya and the Matsya Purana, Triveni Sangam at Prayagraj is the foremost Tirth Sthal for ancestral liberation. Immersing the ashes at the confluence of Ganga, Yamuna, and Saraswati confers Moksha not only upon the departed soul but also liberates ancestors across fourteen generations. While Varanasi (Kashi) and Haridwar are also revered, the scriptural emphasis on Prayagraj for ancestral liberation is especially strong.
