He then takes (the rice), with the text (Vâg. S. I, 10 a, b): 'At the impulse (prasavana) of the divine Savitri, I take thee with the arms of the Asvins, with the hands of Pûshan, thee, agreeable to Agni!' For Savitri is the impeller (prasavitri) of the gods: therefore he takes this as one impelled by Savitri. 'With the arms of the Asvins,' he says, because the two Asvins are the Adhvaryu priests (of the gods). 'With the hands of Pûshan,' he says, because Pûshan is distributer of portions (to the gods), who with his own hands places the food before them. The gods are the truth, and men are the untruth: thus he thereby takes (the rice) by means of the truth.
