What is Tarpan in the context of Gaya?

Tarpan, derived from the Sanskrit root ‘Trup’ (to satisfy), is the Hindu ritual of offering water, often mixed with black sesame seeds (til) and barley (jau), to deities, sages, and especially to deceased ancestors (Pitrus). In Gaya, performing Tarpan holds supreme significance as it’s believed this specific location provides unparalleled spiritual merit, satisfying the ancestors and aiding their journey towards liberation (Moksha).
