Now when, by means of the Sâkamedhâh, the gods were gaining that universal conquest, which now is theirs, they said, 'Verily the fiends, the Rakshas, suck out these (creatures) in the (four) quarters: come, let us throw the thunderbolt at them!' Now the ghee is a thunderbolt: with that thunderbolt, the ghee, they smote the fiends, the Rakshas, in the (four) quarters, and gained that universal conquest which now is theirs. And in like manner does this (Sacrificer) smite the fiends, the Rakshas, in the quarters, by that thunderbolt, the ghee; and thus he gains the victory, thinking, 'May I be consecrated, when safety and security have been gained!'
