Kauṣītaki (Śāṅkhāyana) Brāhmaṇa 30.2.10

30.2.10

carṣaṇī dhṛtam maghavānam ukthyam iti maitrāvaruṇas tasya uktam brāhmaṇam / (soma: hotraka śastrāṇi(tṛtīya savanam))

xxx. 3. 'Holder of the people, the generous, worthy of praise' the Maitrāvaruṇa (says); the explanation of this has been given. The conclusion is by Vasiṣṭha day by day; Vasiṣṭha saw the third pressing for the Maitrāvaruṇa's function; therefore day by day the conclusion is by Vasiṣṭha. In Kakubh verses they give the lead to the Maitrāvaruṇa on the third day; thereby he falls into the power of the Brāhmaṇācchaṅsin. On the fourth day they give the lead to each in his own metre; verily thus each in his own metre they continue finding support. In Gāyatrī verses they give the lead to the Maitrāvaruṇa, in Uṣṇih verses to the Brāhmaṇācchaṅsin, in Anuṣṭubh verses to the Achāvāka, to secure a progressive increase. So their metres increase with four syllables each. In Paṅkti verses they give the lead to the Maitrāvaruṇa on the fifth day, for the fifth day is connected with the Paṅkti; in (verses) of two Padas they give the lead on the sixth day, for the sixth day is connected with (verses) of two Padas. Moreover they perform the Sāmans, Gūrda, Bhadra, Udvaṅcaputra; moreover the Çilpas are accompanied by (verses) of two feet; therefore here the Çilpas are recited, (thinking) 'Let us not depart from the Çilpas.'
