And indeed one may also practise magic by this (offering); for it was thereby that Ârani bewitched Bhadrasena Âgâtasatrava: 'Quick, then, spread (the barhis)!' thus Yâgñavalkya used to say. And by this (offering) indeed Indra also shattered Vritra's retreat; and, verily, he who therewith practises magic shatters thereby the retreat (of his enemy): therefore one may also practise magic with this (offering).
