17.5.15

tasya mana eva brahmā prāṇa udgātā apānaḥ prastotā vyānaḥ pratihartā vāg ghotā.(.hotā.).cakṣur adhvaryuḥ prajātiḥ sadasya ātmā yajamānaḥ / (soma: sodaśin & atiratra)

generation, the sacrificer the body, the Hotrāçaṅsins the limbs. In that the Adhvaryu starts the Stotra, verily thus he unites the eye with the breaths; moreover, verily thus he connects inspiration with the mind. In that the Prastotṛ addresses the Brahman with ‘O Brahman, shall we begin the praise, O Praçāstṛ?’ (it is because they think), ‘Mind is the leader of these breaths; impelled by mind let us sing the Stoma’; moreover, verily thus he connects inspiration with the mind. In that the Brahman approves the Stotra, verily thus he unites the mind with the breaths; moreover, verily thus he connects inspiration with the mind. In that the Prastotṛ begins the praise, verily thus he places inspiration in expiration. In that the Udgātṛ sings, verily thus he places expiration in cross-breathing. In that the Pratihartṛ utters his part, verily thus he places cross-breathing in expiration. So all these deities find support in expiration. In that the Hotṛ connects the Çastra with the Sāman, and the Hotṛ is speech, verily thus he unites speech with the breaths; moreover, verily thus he connects inspiration with mind. In that the Hotrāçaṅsins make a continuity with the Sāman, verily thus they connect the limbs with the breaths. In that the sacrificer sings in accompaniment to the Stotra, and the singers are the breaths, verily thus he places the breaths in himself. Therefore the sun should not set on him outside the altar place, nor should it rise on him, nor should he make preparations, nor utter the invitation, nor say the vaṣaṭ, nor should (the sun) heat (him) when in what is not an altar, (thinking) ‘Let me not sever the body from the breaths.’

xvii. 7. The sacrifice is a man; of him the oblation holders are the head, the Āhavanīya the face, the Sadas the stomach, the litanies the food, the Mārjālīya and the Āgnīdhriya the arms, the altars within the Sadas the internal divinities; the Gārhapatya and (the fire) for cooking the fast milk the support. Again, of him the Brahman priest is the mind, the Udgātṛ the expiration, the Prastotṛ the inspiration, the Pratihartṛ the cross-breathing, the Hotṛ the speech, the Adhvaryu the eye, the Sadasya
