Pārvaṇaśrāddha is an important rite performed during ‘parvans’ i.e., amāvāsyās or new moon days with a view to propitiating the departed forefathers, up to the third generation. On such days, worthy brāhmaṇas are invited for dinner. A portion of the food prepared for the same is taken out in a vessel and seven āhutis or libations are cast into the homa fire with seven appropriate mantras. Two offerings each are made for the father, the grand-father and the great-grand-father and one for all the other pitṛs (forefathers) combined. This rite is known as agnaukaraṇa.
