Now there is one animal sacrifice of the Haviryagña order, and another of the order of the Soma-sacrifice. Of the Haviryagña order is that at which he (the Adhvaryu) brings him fast-food, leads water forward, and pours out a jarful of water, and at which (the Sacrificer) strides the Vishnu-strides; and of the order of the Soma-sacrifice is that (animal sacrifice) at which these (rites) are not performed.
