'The Fathers who are here and who are not here, and whom we know and whom we do not know: Agni, to thee they are known, how many they are, Gâtavedas. May they enjoy what thou givest them in our oblation. Svadhâ! Adoration!
'Your limb that this flesh-devouring (Agni) has burnt, leading you to the worlds (of the Fathers), Gâtavedas, that I restore to you again. Unviolated with all your limbs arise, O Fathers! Svadhâ! Adoration!
'Carry the Âgya, Gâtavedas, to the Fathers, where thou knowest them resting afar. May streams of Âgya flow to them; may their wishes with all their desires be fulfilled! Svadhâ! Adoration!'
In the same way a second and a third verse with the alteration of the Mantra, 'to the grandfathers,' 'to the great-grandfathers.'
