Why is Gaya considered the most important place for Tarpan?

Gaya’s paramount importance stems from Hindu mythology, particularly the story of Gayasur, a pious demon. Lord Vishnu subdued him by placing his foot on his chest, transforming him into the sacred landscape of Gaya. Gayasur was granted a boon that anyone performing ancestral rites like Pind Daan and Tarpan here would ensure the liberation of their ancestors. Lord Vishnu’s presence (as Pitrudev) and the historical performance of rites by figures like Lord Rama make Gaya uniquely potent for Tarpan
