Gokula’s Wonder, Kṛṣṇa’s Bhakta-vaśyatā, the Move to Vṛndāvana, and the Slaying of Vatsāsura and Bakāsura
तं वत्सरूपिणं वीक्ष्य वत्सयूथगतं हरि: । दर्शयन् बलदेवाय शनैर्मुग्ध इवासदत् ॥ ४२ ॥
taṁ vatsa-rūpiṇaṁ vīkṣya vatsa-yūtha-gataṁ hariḥ darśayan baladevāya śanair mugdha ivāsadat
Ketika Bhagavān Hari melihat sang raksasa menyamar sebagai anak sapi dan masuk ke dalam kawanan anak sapi, Ia memberi isyarat kepada Baladeva, “Ini pun raksasa.” Lalu seolah-olah tidak memahami maksudnya, Ia mendekatinya perlahan dengan sikap lugu.
The import of the words mugdha iva is that although Kṛṣṇa knows everything, here He pretended that He did not understand why the demon had entered among the calves, and He informed Baladeva by a sign.
It describes Vatsāsura entering the calf-herd in disguise, and Kṛṣṇa immediately recognizing him and moving in to deal with him while alerting Balarāma.
To inform Balarāma of the disguised danger within the herd, showing their coordinated protection of Vraja even while Kṛṣṇa outwardly acted like an innocent child.
Be alert to hidden threats, but respond calmly and thoughtfully—protecting others without panic, pride, or unnecessary display.
