गोपान् नयन्तं जग्राह वृकं हरिरिवौजसा ॥ ३० ॥
kṛṣṇaḥ śaraṇa-daḥ satām
gopān nayantaṁ jagrāha
vṛkaṁ harir ivaujasā
tasya — of him, Vyomāsura; tat — that; karma — activity; vijñāya — fully understanding; kṛṣṇaḥ — Lord Kṛṣṇa; śaraṇa — of shelter; daḥ — the giver; satām — to saintly devotees; gopān — cowherd boys; nayantam — who was leading; jagrāha — He seized; vṛkam — a wolf; hariḥ — a lion; iva — just as; ojasā — forcefully.
Lord Kṛṣṇa, who shelters all saintly devotees, understood perfectly well what Vyomāsura was doing. Just as a lion grabs a wolf, Kṛṣṇa forcefully seized the demon as he was taking away more cowherd boys.
