Srimad-Bhagavatam: Canto 10 - Chapter 1 - Verse 46
Sanskrit:
श्रीशुक उवाचएवं स सामभिर्भेदैर्बोध्यमानोऽपि दारुण: । न न्यवर्तत कौरव्य पुरुषादाननुव्रत: ॥ ४६ ॥
ITRANS:
śrī-śuka uvācaevaṁ sa sāmabhir bhedairbodhyamāno ’pi dāruṇaḥna nyavartata kauravyapuruṣādān anuvrataḥ
Translation:
Śukadeva Gosvāmī continued: O best of the Kuru dynasty, Kaṁsa was fiercely cruel and was actually a follower of the Rākṣasas. Therefore he could be neither pacified nor terrified by the good instructions given by Vasudeva. He did not care about the results of sinful activities, either in this life or in the next.
