Tarpan is the sacred Hindu ritual of offering water, typically mixed with black sesame seeds (til) and barley (jau), to gratify deities, sages, and primarily, departed ancestors (Pitrus). Performing Tarpan in Prayagraj holds exceptional significance because it is done at the Triveni Sangam, the holy confluence of the Ganga, Yamuna, and the mystical Saraswati rivers. This location is revered as ‘Tirtharaj’ (King of Pilgrimage Sites), making the offerings immensely potent for ancestral peace and liberation (Moksha).
