Kauṣītaki (Śāṅkhāyana) Brāhmaṇa 6.p27

6.p27

vii. 1. The consecration is speech, for by speech is he consecrated. The consecrated is breath; by the consecration as speech, by the consecrated as breath, the gods, having encompassed all desires on both sides, conferred them upon themselves. So verily also the sacrificer, by the consecration as speech, by the consecrated as breath, having encompassed all desires on both sides, confers them upon himself. He offers a cake on eleven potsherds to Agni and Viṣṇu; Agni is of the lower end of the gods, Viṣṇu of the upper end; verily through the two who are of the lower end and the upper end of the gods having encompassed the gods, he obtains identity of world with them. Therefore he who first has consecrated himself will attain his desire, for by him first are the gods encompassed. He consecrates himself with incorporeal breath consecrations; the fore-offerings are expirations, the after-offerings inspirations. In that they proceed with the fore-offerings and the after-offerings, thus expirations and inspirations are consecrated; in that (they proceed) with an oblation, thus the body (is consecrated). He with the body being consecrated obtains all desires; with expirations and inspirations being consecrated, identity of world and union with all the deities.
