Srimad-Bhagavatam: Canto 10 - Chapter 1 - Verse 17

Sanskrit:

पशूंश्चारयतोर्गोपैस्तद्वने रामकृष्णयो: ।गोपरूपी प्रलम्बोऽगादसुरस्तज्जिहीर्षया ॥ १७ ॥

ITRANS:

paśūṁś cārayator gopaistad-vane rāma-kṛṣṇayoḥgopa-rūpī pralambo ’gādasuras taj-jihīrṣayā

Translation:

While Rāma, Kṛṣṇa and Their cowherd friends were thus tending the cows in that Vṛndāvana forest, the demon Pralamba entered their midst. He had assumed the form of a cowherd boy with the intention of kidnapping Kṛṣṇa and Balarāma.

Purport:

Having described how Kṛṣṇa and Balarāma acted just like ordinary boys, Śukadeva Gosvāmī will now reveal one of the Lord’s transcendental pastimes that is beyond the range of human activity. According to Śrīla Viśvanātha Cakravartī Ṭhākura, the demon Pralamba disguised himself as a particular cowherd boy who on that day had remained at home with duties to perform.
