Śrīmad-Bhāgavatam · Text 10.44.39
Who is speaking and story frame
स नित्यदोद्विग्नधिया तमीश्वरंपिबन्नदन्वा विचरन् स्वपन् श्वसन् । ददर्श चक्रायुधमग्रतो यत-स्तदेव रूपं दुरवापमाप ॥ ३९ ॥
sa nityadodvigna-dhiyā tam īśvaraṁ
pibann adan vā vicaran svapan śvasan
dadarśa cakrāyudham agrato yatas
tad eva rūpaṁ duravāpam āpa
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.
