Srimad-Bhagavatam: Canto 6 - Chapter 1 - Verse 24
Sanskrit:
कदा नु भ्रातृहन्तारमिन्द्रियाराममुल्बणम् ।अक्लिन्नहृदयं पापं घातयित्वा शये सुखम् ॥ २४ ॥
ITRANS:
kadā nu bhrātṛ-hantāramindriyārāmam ulbaṇamaklinna-hṛdayaṁ pāpaṁghātayitvā śaye sukham
Translation:
Lord Indra, who is very much fond of sense gratification, has killed the two brothers Hiraṇyākṣa and Hiraṇyakaśipu by means of Lord Viṣṇu. Therefore Indra is cruel, hardhearted and sinful. When will I, having killed him, rest with a pacified mind?
