These two animal victims, whilst being such, are seized (by some) in a different way. The one that is seized for Aditi, (some) seize for the Âdityas,--the Âdityas being the All, he (the priest) thereby makes him the embryo of the All (universe). And the one that is seized for the Maruts, (some) seize for the All-gods,--the All-gods being the All, he thereby makes him the embryo of the All.
