Sanskrit:
तं विद्वानपि दाशार्हो भगवान् सर्वदर्शन: ।अन्वमोदत तत्सख्यं वधं तस्य विचिन्तयन् ॥ १८ ॥
ITRANS:
taṁ vidvān api dāśārhobhagavān sarva-darśanaḥanvamodata tat-sakhyaṁvadhaṁ tasya vicintayan
Translation:
Since the Supreme Lord Kṛṣṇa, who had appeared in the Daśārha dynasty, sees everything, He understood who the demon was. Still, the Lord pretended to accept the demon as a friend, while at the same time seriously considering how to kill him.
