Whilst standing at the right thigh of the Vedi, with his face to the east, he throws it southwards, with, 'Let thy pain enter him whom we hate!' and thus its pain enters whomsoever he hates. He may say, 'Let thy pain enter so-and-so!' naming him whom he hates, and then he has no longer any hold upon him; but let him take no notice of this, for indicated of himself is he whom he who knows this hates. If it should remain unbroken, let him bid (the Pratiprasthâtri) to break it; for only when it is broken, the pain enters him whom he hates. They return (to the altar) without looking back: they thus leave pain and evil behind without looking back to them.
