pañcasūnākṛtaṃ pāpaṃ tathā'dharmakṛtaṃ ca yat ..
kṛmikīṭapataṃgāśca nihatāḥ pathi gacchatā ..
parānnaṃ parapānīyamaspṛśya sparśasaṃgamam ..
tatsarvaṃ nāśamāpnoti bhagavatketudarśanāt .. 34..

The sin committed through the five slaughterhouses, and whatever was committed by unrighteousness, / the worms, insects, and moths killed while walking on the road, / the eating of another's food, drinking of another's water, and contact with the untouchable— / all that is destroyed by the darśana of the Lord's banner. 34
