27.2.13

tad āhur na anuṣṭubha āyatanam riñcyāt / (soma: daśamam ahah)

They say, 'He should not abandon the abode of the Anuṣṭubh; there should he recite Virāj verses; the Virāj and the Anuṣṭubh are the same metre, for not by one syllable is a metre made different, nor yet by two.' Of these two triplets there are six syllables over, and six of the strophe and antistrophe of the Agniṣṭoma Sāman; these twelve syllables the Hotṛ should make up in the morning litany. He need not trouble as to this; it is made up here. 'There is an Uṣṇih additional,' we hold, 'or a Gāyatrī; that he should make up at the morning litany.' He need not trouble about this; it is made up here.
