Gaya-ji is unparalleled! Lord Rama himself performed Shraddh for his father, Dasharatha, here. The Gaya Mahatmya and Puranas declare Gaya as the Moksha Bhumi specifically for Pitrs. The key reason is the presence of Lord Vishnu’s footprint (Vishnupad) enshrined in the main temple here in Gaya. It is believed that offering Pindas at Vishnupad ensures the ancestors attain liberation directly.
Furthermore, the Phalgu River in Gaya, though often appearing dry on the surface, flows underground and is considered sacred. Offerings made on its banks or at the designated vedis (altars) throughout Gaya reach the ancestors without fail, granting them complete satisfaction (tripti), which is the unique power of Shraddh in Gaya.
