"Having next recited the prayer for the discomfiture of malignant spirits, and scattered sesamum-seeds upon the ground, the Brahmans who have been fed are to be addressed, in common with the ancestors of the sacrificer, in this manner: 'May my father, grandfather, and great grandfather, in the persons of these Brahmans, receive satisfaction! May my father, grandfather, and great grandfather derive nutriment from these oblations to fire! May my father, grandfather, and great grandfather derive satisfaction from the balls of food placed by me upon the ground! May my father, grandfather, and great grandfather be pleased with what I have this day offered them in faith! May my maternal grandfather, his father, and his father, also enjoy contentment from my offerings! May all the gods experience gratification, and all evil beings perish! May the lord of sacrifice, the imperishable deity Hari, be the acceptor of all oblations made to the manes or the gods! and may all malignant spirits, and enemies of the deities, depart from the rite.'
