i. 18 (iv. 1). The sacrifice went away from the gods (saying), 'I shall not be your food.' 'No', replied the gods, 'Verily thou shalt be our food.' The gods crushed it; it being taken apart was not sufficient for them. The gods said 'It will not be sufficient for us, being taken apart; come, let us gather together the sacrifice.' (They replied) 'Be it so'. They gathered it together; having gathered it together they said to the Açvins, 'Do ye two heal it', the Açvins are the physicians of the gods, the Açvins the Adhvaryus; therefore the two Adhvaryus gather together the cauldron. Having gathered it together they say, 'O Brahman, we shall proceed with the Pravargya offering; O Hotṛ, do thou recite.'
