ITRANS:
indra uvācastrī-bhū-druma-jalair enoviśvarūpa-vadhodbhavamvibhaktam anugṛhṇadbhirvṛtra-hatyāṁ kva mārjmy aham
Translation:
King Indra replied: When I killed Viśvarūpa, I received extensive sinful reactions, but I was favored by the women, land, trees and water, and therefore I was able to divide the sin among them. But now if I kill Vṛtrāsura, another brāhmaṇa, how shall I free myself from the sinful reactions?
