Kauṣītaki (Śāṅkhāyana) Brāhmaṇa 18.p7

18.p7

seventy Anuṣṭubh and seventy Paṅkti verses are one hundred and forty Bṛhatī verses; deducting a hundred Gāyatrī from three hundred Triṣṭubh verses there are three hundred Bṛhatī verses; the hundred Gāyatrī verses and a hundred Jagatī verses are two hundred Bṛhatī verses; fifty Triṣṭubh and fifty Uṣṇih verses make up a hundred Bṛhatī verses; then there are fifty-seven Bṛhatī verses actually found; the fifty-first and fifty-second Triṣṭubh verses and (the verse) of two Padas are three Bṛhatī verses; thus a thousand Bṛhatīs are made up from a thousand of varied metres. ‘He should not recite over a thousand, nor less than a thousand’ is the rule; the expansion of the Āçvina is however conspicuous. This is a service for Agni; verily he should not fall away from the service for Agni; if he should pass over the service for Agni before the due time, he should apply there whatever in the Āçvina is addressed to two gods in the Ṛcs; in the service for Sūrya (he should use) (the verses) for Soma, the purifying, according to metre, Gāyatrī in Gāyatrī, Triṣṭubh in Triṣṭubh, Jagatī in Jagatī; all that is connected with Sūrya in the place of (the service) for Sūrya; all Pragāthas to Indra in the place of the Pragātha; all to sky and earth in the place of (the hymn) to sky and earth; all (verses) of two Padas in the place of (the verse) of two Padas; all addressed to Bṛhaspati before the final verse. That is whatever of the Ṛcs is not set forth.
