Srimad-Bhagavatam: Canto 10 - Chapter 1 - Verse 39

Sanskrit:

स नित्यदोद्विग्नधिया तमीश्वरंपिबन्नदन्वा विचरन् स्वपन् श्वसन् । ददर्श चक्रायुधमग्रतो यत-स्तदेव रूपं दुरवापमाप ॥ ३९ ॥

ITRANS:

sa nityadodvigna-dhiyā tam īśvaraṁpibann adan vā vicaran svapan śvasandadarśa cakrāyudham agrato yatastad eva rūpaṁ duravāpam āpa

Translation:

Kaṁsa had always been disturbed by the thought that the Supreme Lord was to kill him. Therefore when drinking, eating, moving about, sleeping or simply breathing, the King had always seen the Lord before him with the disc weapon in His hand. Thus Kaṁsa achieved the rare boon of attaining a form like the Lord’s.

Purport:

Although born out of fear, Kaṁsa’s constant meditation on the Supreme Lord eradicated all his offenses, and therefore the demon was liberated upon his death at the Lord’s hands.
