XIII, 51), 'Verily, the he-goat was produced from Agni's heat;'--that which was produced from Pragâpati's heat, was indeed produced from Agni's heat;--'he saw the progenitor at first,' the progenitor doubtless is Pragâpati: thus, 'he saw Pragâpati at first;'--'thereby the gods at first (agre) went to the godhead;' the he-goat doubtless is speech; and from speech the gods doubtless first went to the godhead, to the summit (agram);--'thereby they went to the height, the wise;' the height doubtless is the heavenly world: thus, 'thereby they went to the heavenly world, the wise;'--'The wild sarabha do I assign unto thee,'--he thereby assigns the wild sarabha to him;--'building up therewith thy forms, get thee settled!' that is, 'building up therewith, perfect thyself!'--'Let thy burning heat reach the sarabha! let thy burning heat reach him whom we hate!' he thereby lays burning heat into the sarabha, and into him whom he hates.
