The procedure typically involves taking a purifying bath in the nearby Tapt Kund or the Alaknanda river. Under the guidance of a Pandit at Brahmakapal ghat, you’ll face south and offer water mixed with black sesame seeds (til), barley (jau), and Kusha grass. Chanting specific mantras, you invoke your ancestors by name and lineage, offering the water mixture from your palms (anjali) to satisfy their souls. The Pandit guides the specific sequence, offerings, and mantras according to your family traditions and the scriptures.
