On the space between (the Sacrificer and the bricks) he pours out a jarful of water,--water is a thunderbolt: with a thunderbolt he thus separates from himself evil, corruption. With 'Homage to (the goddess of) Prosperity who hath done this!' they rise, for it was with a view to prosperity that the gods at first performed this rite, and to that (goddess) they then rendered homage; and for prosperity indeed this (Sacrificer) now performs this rite, and to that (goddess) he now renders homage. They go back (to the sacrificial ground) without looking back: they thus abandon evil, corruption, even without looking back to it.
