While both Pind Daan and Tarpan are ancestral rites performed at Brahmakapal, they serve distinct purposes. Pind Daan involves offering physical nourishment in the form of rice/barley balls (Pindas) to provide substance and liberation to the departed souls (Pitr). It’s a more substantial offering aimed at freeing them from the subtle body and helping their passage. Tarpan, on the other hand, is primarily an offering of water mixed with sesame seeds, aimed at quenching the thirst and satisfying not just ancestors (Pitr), but also gods (Devas) and sages (Rishis). Both are often performed together at Brahmakapal for comprehensive ancestral appeasement, but Pind Daan is specifically focused on offering food sustenance for liberation.
