The primary and most sacred location for the Tarpan in Gaya is the banks of the Phalgu River. Specific ghats (steps leading to the river) are designated for these rituals. Tarpan is often performed standing in pits dug into the sandy riverbed to reach the underground water. It’s also integral to the broader Shraddha/Pind Daan ceremonies, which involve rites at the Vishnupad Temple and Akshayavat (the immortal banyan tree).
