paryagnaye kriyamāṇāyānubrūhīty āhādhvaryur
agnir hotā no adhvara iti
tṛicam āgneyaṃ gāyatram anvāha paryagni kriyamāṇe,
svayaivainaṃ tad devatayā svena chandasā samardhayati
vājī san pari ṇīyata iti.
vājinam iva hy enaṃ santam pariṇayanti
pari triviṣṭy adhvaraṃ yāty agnī rathīr ivety.
eṣa hi rathīr ivādhvaram pariyāti
pari vājapatiḥ kavir ity. eṣa hi vājanam= patir
ata upapreṣya hotar havyā devebhya ity āhādhvaryur
ajaid agnir asanad vājam iti maitrāvaruṇa upapraiṣam pratipadyate
tad āhur: yad adhvaryur hotāram upapreṣyaty,
atha kasmān maitrāvaruṇa upapraiṣam pratipadyata iti
mano vai yajñasya maitrāvaruṇo, vāg yajñasya hotā.
manasā vā iṣita vāg vadati.
yāṃ hy anyamanā vācaṃ vadaty, asuryā vai sā vāg adevajuṣṭā.
tad yan maitrāvaruṇa upapraiṣam pratipadyate manasaiva tad vācam īrayati,
tan manaseritayā vācā devebhyo havyaṃ sampādayati

ii. 5 (vi. 5). ‘Recite for the carrying round of fire’ the Adhvaryu says. ‘Agni, the Hotṛ, at our sacrifice’, this triplet to Agni in Gāyatrī he recites when the carrying round of fire is being performed; verily thus with his own deity, his own metre, he makes him prosper. ‘Being a steed he is carried round’ (he says), for him being as it were a steed they carry round. ‘Thrice round the sacrifice Agni goeth like a charioteer’ (he says), for he like a charioteer goes round the sacrifice. ‘The lord of strength, the sage’ (he says), for he is the lord of strength. ‘Do thou give the supplementary direction, O Hotṛ, for the oblations for the gods’ the Adhvaryu says. ‘Agni hath conquered, he hath won strength’, thus the Maitrāvaruṇa begins the supplementary direction. They say, ‘Since the Adhvaryu gives the order for supplementary directions to the Hotṛ, then why does the Maitrāvaruṇa begin the supplementary direction?’ The Maitrāvaruṇa is the mind of the sacrifice; the Hotṛ is the voice of the sacrifice; instigated by mind voice speaks, for the speech which one speaks with his mind elsewhere, that speech is demoniacal and not acceptable to the gods. In that the Maitrāvaruṇa begins the supplementary direction, verily thus with mind he sets speech in motion; with speech set in motion by mind he provides the oblation for the gods.
