oblation to the Rudras and the third (i.e. evening)
oblation to the Adityas and the Visve-devas, "Where,

when this life is over. Svaha!" Afterwards the sacrificer
chants: "Cast away the bolt of the earth-world." Having
said this, he rises. To him the Vasus offer the world
connected with the morning oblation.
