The sprinkling-water which is left he pours outside the altar close to where is the southern of those two front corners (of the high altar) with, 'This burning water I dismiss from the sacrifice.' Because she (Vâk--the altar) on that occasion became a lioness and roamed about unappeased, he thus dismisses from the sacrifice that sorrow of hers,--if he do not wish to exorcise. But should he wish to exorcise, let him indicate it by saying, 'This burning water I dismiss from the sacrifice against so and so!' He then smites him with that sorrow, and sorrowing he goes to yonder world.
