That which is spilt he touches, with the formulas (Vâg. S. II, 2), 'To the Lord of the Earth--svâhâ!' 'To the Lord of the World--svâhâ!' 'To the Lord of Beings--svâhâ!' These, indeed, are the names of those Agnis,--to wit, Lord of the Earth, Lord of the World, and Lord of Beings. Thus in like manner as that (oblation) which is accompanied by 'Vashat' is offered up (to the particular deity to which it is announced), so is this (offered up) on his (the sacrificer's) part to those Agnis.
