Kauṣītaki (Śāṅkhāyana) Brāhmaṇa 29.3.12

29.3.12

atha etānt sāma pragāthān anuśaṃsanti /

the Pragāthas of the Sāman; thus they depart not from the Hotṛ's rule. The beginnings of the litanies of the Maitrāvaruṇa and Achāvāka are of five verses, the conclusions are of eleven verses; verily thus they make the two ends alike. The Maitrāvaruṇa recites (verses) by Viçvāmitra and Vāmadeva, for his conclusion is by Vāmadeva. The Brāhmaṇācchaṅsin recites (verses) by Viçvāmitra and Vasiṣṭha, for his conclusion is by Vasiṣṭha. The Achāvāka recites (verses) by Bharadvāja and Viçvāmitra, for his conclusion is by Viçvāmitra. They recite (verses) by four Ṛṣis; up to four (degrees) are pairing, union, propagation; (they serve) for generation. The beginnings of the litanies of the Maitrāvaruṇa and Brāhmaṇācchaṅsin are by Viçvāmitra, and so is the conclusion of the Achāvāka; Viçvāmitra is speech; verily thus with speech on all sides they extend the sacrifice. This is the explanation of the introductory and concluding rites and of the one day form.
