v. 4. 12.

'Be 'pure for the winning of strength', this is the Anustubh strophe; three Anustubhs make four Gayatris; in that there are three Anustubhs, therefore the horse when standing stands on three feet; in that there are four Gayatri is, therefore he goes putting down all four feet. The Anustubh is the highest of metres, the fourfold Stoma is the highest of Stomas, the three-night sacrifice the highest of sacrifices, the horse the highest of animals; verily by the highest he makes him go to the highest state. It is the twenty-onefold day [1], on which the horse is slain, there are twelve months, five seasons; these worlds are three; the twenty-onefold (Stoma) is yonder sun; this is Prajapati, the horse is connected with Prajapati; verily he wins it straightway. The Prstha (Stotra) is of Çakvari verses to make the horse complete, there are various metres, different sets of animals are offered, both domesticated and wild; in that the Prstha is of Çakvari verses, (it is) to complete the horse. The Saman of the Brahman is that of Prthuraçmi; by the rein the horse is restrained [2], a horse unrestrained and unsupported is liable to go to the furthest distance; (verily it serves) to restrain and support the horse. The Achavaka's Saman is the Samkrti; the horse sacrifice is an extensive sacrifice; 'who knows', they say, 'if all of it is done or not?' In that the Achavaka's Saman is the Samkrti, (it serves) to make the horse whole, to win it entirely, to prevent interference. The last day is an Atiratra with all the Stomas, to obtain all, to conquer all; verily he obtains all, he conquers all with it.
