vii. 5. 5.

If two libations are offered simultaneously, then one should perform the early litany in the advanced part of the night. He who does it first wins the speech, the gods, and the metres (of the others). The strophe should contain the word 'strong (vrsan)'; verily he takes Indra away from their morning pressing. Or rather they say, 'The strophe at the beginning of each pressing should be of this kind'; verily he takes Indra away from each of their pressings.
For entry, for rest, for the overcoming, of the Gayatri, of the Tristubh, of the Jagati, of the Anustubh, of the Pankti, hail!
Entry and rest are the metres; verily by the metres [1], he takes away their metres. One should recite the Sajaniya hymn; one should recite the Vihavya hymn; one should recite the Kayaçubhiya hymn of Agastya. This indeed is so much as that, verily he takes away so much as is theirs. If at the early pressing the bowl is broken, they should sing verses addressed to Visnu and containing the epithet Çipivista. Whatever in the sacrifice is redundant, is redundant with regard to Visnu Çipivista; verily Visnu Çipivista places the redundant in the redundant. Verily having obtained the redundant by the redundant, they win it. If it is broken at the midday pressing, they should make the Saman have the Vasatkara as its finale. The support of the sacrifice is the Vasatkara; verily they make the Saman obtain support. If it breaks at the third pressing, the same thing (should be done).
