Gokula’s Wonder, Kṛṣṇa’s Bhakta-vaśyatā, the Move to Vṛndāvana, and the Slaying of Vatsāsura and Bakāsura
कदाचिद् यमुनातीरे वत्सांश्चारयतो: स्वकै: । वयस्यै: कृष्णबलयोर्जिघांसुर्दैत्य आगमत् ॥ ४१ ॥
kadācid yamunā-tīre vatsāṁś cārayatoḥ svakaiḥ vayasyaiḥ kṛṣṇa-balayor jighāṁsur daitya āgamat
วันหนึ่ง ขณะพระกฤษณะและพระพลรามพร้อมสหายกำลังเลี้ยงลูกวัวอยู่ริมฝั่งยมุนา อสูรตนหนึ่งผู้มุ่งหมายจะสังหารพระองค์ทั้งสองก็เข้ามา
This verse describes how, even during Kṛṣṇa’s simple cowherd pastime on the Yamunā’s bank, a demon comes with the intention to kill Him—highlighting the repeated asuric opposition to the Lord’s Vraja-līlā.
To set the scene of Kṛṣṇa’s innocent pastoral pastime and then contrast it with the demon’s violent intent, showing how the Lord protects His friends and destroys threats to Vraja.
A devotee continues simple, sincere devotional life despite disturbances, trusting that remembrance of Kṛṣṇa and steady bhakti bring inner protection and clarity amid “demonic” obstacles like fear, envy, and hostility.
