The Pratiprasthâtri sits down, after taking the two offering-spoons in his hand. The Adhvaryu then proceeds with those oblations,--viz. Agni's cake on eight potsherds, Soma's pap, Savitri's cake on twelve or eight potsherds, Sarasvatî's pap, Pûshan's pap, and Indra and Agni's cake on twelve potsherds.
