nārayo 'bhibhavanty etān
viṣṇu-pakṣān ivāsurāḥ
ye -- those persons who; etasmin -- unto this child; maha-bhage -- most auspicious; pritim -- affection; kurvanti -- execute; manavah -- such persons; na -- not; arayah -- their enemies; abhibhavanti -- do overcome; etan -- those who are attached to Krishna; vishnu-pakshan -- the demigods, who always have Lord Vishnu on their side; iva -- like; asurah -- the demons.
Srila Prabhupada has especially indicated in this connection that just as Lord Krishna's associates could not be defeated by Kamsa, so His modern-day devotees will not be defeated by their demoniac opponents, nor will the Lord's devotees be defeated by the internal enemies -- the lusty, materialistic senses.
