Śatapatha Brāhmaṇa ("of a hundred paths") 5.1.5

Now when they run a race, he thereby wins this same (terrestrial) world. And when the Brahman sings a Sâman on the cart-wheel set up on (a post) reaching to his navel, he thereby wins the air-world. And when he erects the sacrificial post, he thereby wins the world of the gods. Hence that threefold performance.

The Brahman mounts a cart-wheel, set up on (a post) as high as his navel, with (Vâg. S. IX, 10), 'At the impulse (sava) of the god Savitri, of true impulsion, may I ascend unto the highest heaven of Brihaspati!' thus, if a Brâhmana sacrifices; for Brihaspati is the Brahman (priesthood, or sanctity), and the Brâhmana is the Brahman.

And if a Râganya sacrifices, (he does so) with, 'At the impulse of the divine Savitri, of true impulsion, may I ascend unto the highest heaven of Indra!' for Indra is the Kshatra (nobility, or power), and the Râganya is the Kshatra.

Thrice he sings the Sâman. Having thrice sung it, he descends with, 'At the impulse of the divine Savitri, of true impulsion, I have ascended unto the highest heaven of Brihaspati!'--thus, if a Brâhmana sacrifices, for Brihaspati is the Brahman, and the Brâhmana is the Brahman.

And if a Râganya sacrifices,--with, 'At the impulse of the divine Savitri, of true impulsion, I have ascended unto the highest heaven of Indra!' for Indra is the Kshatra, and the Râganya is the Kshatra.

They put up seventeen drums along the edge of the altar, from the Âgnîdhra backwards (towards the west); for he who offers the Vâgapeya wins Pragâpati; but Pragâpati is speech, and that doubtless is the supreme speech which is (the outcome) of seventeen drums: he thus wins the supreme speech, the supreme Pragâpati. Seventeen there are, because Pragâpati is seventeenfold: he thus wins Pragâpati.

One of these drums he (the Brahman) beats (while praying) with a sacrificial formula: thereby all of them become beaten with a sacrificial formula.

He beats it with (Vâg. S. IX, 11), 'O Brihaspati, win the race! lift ye up your voice unto Brihaspati: make ye Brihaspati win the race!' thus, if a Brâhmana sacrifices; for Brihaspati is the Brahman, and the Brâhmana is the Brahman.

And if a Râganya sacrifices, (he does so) with, 'O Indra, win the race! lift ye up your voice unto Indra: make ye Indra win the race!' for Indra is the Kshatra, and the Râganya is the Kshatra.

And when those race-running chariots have come up again, he takes down one of those drums with a sacrificial formula; whereby they all become taken down with a formula.

He takes it down, with (Vâg. S. I X, 12), 'This hath been your true concord whereby ye (drums) have caused Brihaspati to win the race;--Brihaspati ye have caused to win the race: be released, ye wood-lords!' thus, if a Brâhmana sacrifices; for Brihaspati is the Brahman, and the Brâhmana is the Brahman.

And if a Râganya sacrifices, with, 'This hath been your true concord whereby ye have caused Indra to twin the race;--Indra ye have caused to win the race: be released, ye wood-lords!' for Indra is the Kshatra, and the Râganya is the Kshatra.

A Râganya then shoots seventeen arrow's ranges northwards from the edge of the altar; for as much as is one arrow's range, so much is Pragâpati crosswise; and as much as are seventeen arrow's ranges, so much is Pragâpati lengthwise.

And as to why a Râganya shoots,--he, the Râganya is most manifestly of Pragâpati (the lord of creatures): hence, while being one, he rules over many; and because 'pragâpati' has four syllables, and 'râganya ' also has four syllables, therefore a Râganya shoots. He shoots seventeen arrow's ranges, because Pragâpati is seventeenfold: he thereby wins Pragâpati.

And whichever (horse) he yokes with a formula, up to that the Sacrificer now steps, with (Vâg. S. IX, 13), 'At the impulse of the divine Savitri, of true impulsion, may I win the race of the race-winning Brihaspati!'

And even as then Brihaspati hasted up to Savitri for his impulsion,--Savitri being the impeller among the gods--saying, 'Impel this for me: impelled by thee, may I win this!' and Savitri, as the impeller, impelled it for him, and impelled by Savitri, he won; in like manner does he thereby haste up to Savitri for his impulsion,--Savitri being the impeller among the gods,--saying, 'Impel this for me: impelled by thee, may I win!' and Savitri, as the impeller, impels it for him, and impelled by Savitri he wins.

And if a pupil of the Adhvaryu's or some (other) theological student were to know that prayer, stepping up he makes (the Sacrificer) say, 'O coursers!'--for horses are indeed coursers: therefore he says, 'O coursers'--'wealth-winners!' for wealth is food: 'food-winners' he thereby says;--'keeping the roads,' for they indeed run keeping (within) the roads;--'measuring the stages;' for measuring the stages they run over the course;--'go ye to the winning-post!' In order that the evil-doers, the Rakshas, may not hurt them midways, he thus says this.--They run the race, they beat the drums, and he (the Brahman) sings the Sâman.

He (the Adhvaryu) then either offers or addresses (the horses) with those two gagatî-verses: whether he offers, or whether he addresses (the horses), the significance (of the performance) is the same.

He offers, with (Vâg. S. IX, 14; Rik S. IV, 40, 4), 'That courser speedeth after the whip, fettered at the neck and shoulder and mouth: may Dadhikrâ win according to his power; may he run along the windings of the roads, hail!'

[Vâg. S. IX, 15; Rik S. IV, 40, 3], 'And of him, the running, speeding, there fanneth like the wing of the eager bird,--as of the gliding eagle,--about the breast of Dadhikrâvan passing along with might, hail!'

He then either offers or addresses (the horses) with the following tristich: this is twofold, because he either offers or addresses. Whether he offers, or addresses (the horses), the significance is the same: he thereby speeds those running horses, imbues them with energy. There are here three earths, namely this one, and two beyond it: these he thereby wins.

He addresses (the horses, with Vâg. S. IX, 16; Rik S. VII, 38, 7), 'Auspicious be the coursers unto us at the invocations in the divine service, running their measured course, with beautiful song; swallowing the dragon, the wolf, the evil spirits: may they ever keep away from us affliction!'

[Vâg. S. IX, 17; Rik S. X, 64, 6], 'Those racers, wont to hear the calls, may they all hear our call, the coursers running their measured course: they, the winners of thousands, eager to win at the winning of oblations, who have carried off great gain in the contests.'

[Vâg. S. IX, 18; Rik S. VII, 38, 8], 'In every race, help us, ye racers, at the prizes, ye wise, immortal knowers of the divine law: drink of this mead, be gladdened, and satisfied walk ye on the paths trodden by the gods!'

He then steps over against (the horses) with the Bârhaspatya pap, and touches it; for he who offers the Vâgapeya wins food, since 'vâga-peya' is the same as 'anna-peya:' whatever food he has thus gained that he now, having reached that goal, brings in contact with himself, puts within himself.

He touches it, with (Vâg. S. IX, 19), 'May gain of wealth come to me!' wealth means food: he thus says, 'May gain of food come (accrue) to me;'--'May these two, Heaven and Earth, the all-shaped, come to me!' for Pragâpati is Heaven and Earth;--'May father and mother come to me!' for Pragâpati is both father and mother;--'May Soma come to me with immortality!' for Pragâpati is Soma.

He makes the horses smell it, with, 'Ye coursers!' for horses are coursers: therefore he says, 'Ye coursers! wealth-winners!' wealth is food: 'food-winners' he thereby says;--'having run the course--' for 'starting (upon the course)' he said before, as then they were indeed starting; but now he says, 'having run,' for they indeed have run (the race): therefore he says, 'having run;'--'smell ye Brihaspati's portion--' for this is Brihaspati's portion: therefore he says, 'Smell ye Brihaspati's portion;'--'taking (it) in!' whereby. he imbues the Sacrificer with energy. And as to why he makes the horses smell,--he made them smell before, thinking, 'May I win this (world);' and now (he does so) thinking, 'I have won this (world) that is why he makes the horses smell.
