tatra śakro vipāpmābhūddhatvā garbhaṃ diteḥ purā ..
viśvastāyā viśeṣeṇa mātuḥ kākutsthasattama ..
tasmāttatra drutaṃ gatvā snānaṃ kuru mahāmate .. 68 ..

There Indra became free of sin after killing the fetus of Diti of old, / the mother who had placed special trust [in him], O best of the Kakutsthas. / Therefore, go there quickly and perform ritual ablution, O highly intelligent one. (68)
