11.5.2.9

tadāhuḥ svargāyatraṃ vaiśvadevaṃ haviḥ syātsarvatraiṣṭubhaṃ varuṇapraghāsāḥ sarvajāgatam mahāhaviḥ sarvānuṣṭubhaṃ śunāsīrīyaṃ catuṣṭomasyāpsyā iti tadu tathā na kuryādyattvā etānyabhisampadyante tenaivāsya sa kāma upāpto bhavati

As to this they say, 'The Vaisvadeva oblation (should have) all (its formulas) in the Gâyatrî, the Varunapraghâsâh all in the Trishtubh, the Great Oblation all in the Gagatî, and the Sunâsîrîya all in the Anushtubh metre, so as to yield a Katushtoma.' But let him not do this, for inasmuch as (his formulas) amount to these (metres) even thereby that wish is obtained.
