Having called for the sraushat (and been responded to by the Âgnîdhra), he thus addresses (the Hotri), 'The divine Hotris are summoned--,' the divine Hotris, namely, are (represented by) these enclosing-sticks, since these are Agnis (fires). When he says, 'the divine Hotris are summoned (ishita),' he means to say, 'the divine Hotris are wished for (ishta).' [He continues], '--for the proclamation of success,'--for on this the gods themselves are indeed intent, to wit, that they should speak what is favourable (conducive to success, sâdhu), that they should do what is favourable: hence he says 'for the proclamation of success.'--'The human one is called upon for the song of praise (sûktavâka)!' by these words he urges on this human Hotri to singing praises.
