' In that (the cups) are drawn in one vessel, therefore there is one breath within; they are offered in two vessels, therefore the breaths outside are in pairs. Those that are for two deities are the breaths, the Ida is cattle; if he should summon the Ida before those that are for two deities [3], he would obstruct his breaths by cattle, he would be likely to perish. Having eaten those for two deities, he summons the Ida; verily having placed the breaths in himself he summons the Ida. (The cup) for Indra and Vayu is speech, that for Mitra and Varuna is the eye, that for the Açvins is the ear; he eats in front that for Indra and Vayu, therefore in front he speaks with speech; in front that for Mitra and Varuna, therefore in front he sees with the eye; moving all round, that for the Açvins; therefore on all sides he hears with the ear. Those for two deities are the breaths [4], he sets down full vessels; therefore the breaths are full within; wherever in the performance of the sacrifice nothing is done, in that place the Raksases attack the sacrifice; in that he sets down full vessels the part of the sacrifice being performed is deposited to prevent the entry of the Raksases. He sets down in the north track of the southern oblation-cart; verily he places speech in speech. They lie (there) until the third pressing, for the continuity of the sacrifice.

For them they drew these cups for Çukra and Manthin; then did the gods prosper, the Asuras were defeated. He for whom knowing thus these Çukra and Manthin (cups) are drawn, prospers himself, his foe [1] is defeated. Having driven away these two, the gods offered to themselves,' to Indra.
