apahateti triryavavikiraṇam /
oṃ nihanmi sarvaṃ yadamedhyavadbhaveddhatāśca sarve 'suradānavā mayā /
rakṣāṃsi yakṣāḥ sapiśācasaṅghā hatā mayā yātudhānāśca sarve iti siddhārthavikiraṇam //

Saying, "Driven away...", barley is scattered three times. / Saying, "Om, I strike down all that may be unholy; and all asuras and dānavas have been slain by me; / the rakṣasas, the yakṣas, together with hosts of piśācas, have been slain by me, and all yātudhānas," white mustard seeds are scattered.
