2.2.1.6

sa vā agnaye pavamānāya nirvapati | prāṇo vai pavamānaḥ prāṇamevāsminnetaddadhāti tadvetayaivāsmiṃstaddadhātyannaṃ hi prāṇo 'nnameṣāhutiḥ

He takes out (material for an oblation) to Agni Pavamâna (the Blowing). Now the blowing one is the breath, so that he thereby puts breath into him (the sacrificer). And this he puts into him by means of this (offering); for breath means food, and this offering also is food.
