"Om, today, in this region, in such-and-such month, when the sun has entered such-and-such zodiacal sign, on such-and-such lunar day, I shall perform the śrāddha preceded by the Viśvedevas for our fathers, grandfathers, and great-grandfathers of such-and-such gotras and names! Om, svāhā to the Viśvedevas! Om, I shall invoke the Viśvedevas!" / When it is replied, "Invoke [them]," [he recites:] "Om, Viśvedevas, come together, hear this invocation of mine; / sit down upon this sacred grass. Om, Viśvedevas, hear this of mine, you who are in the atmosphere, you who dwell in heaven; / you whose tongue is fire, and you worthy of sacrifice, having sat down upon this sacred grass, rejoice! / Om, the medicinal herbs converse together with King Soma: / 'For whomever a brāhmaṇa prepares [us], him, O King, do we save!' / Om, may the fortunate Viśvedevas of great power come; / may those who are appointed here in this śrāddha be attentive! / Om, driven away are the asuras, the rakṣasas that dwell around the altar"—thus barley is scattered three times.
