Śrīmad-Bhāgavatam · Text 10.26.21
Who is speaking and story frame
य एतस्मिन् महाभागे प्रीतिं कुर्वन्ति मानवा:
। नारयोऽभिभवन्त्येतान् विष्णुपक्षानिवासुरा: ॥ २१ ॥
ya etasmin mahā-bhāge
prītiṁ kurvanti mānavāḥ
nārayo ’bhibhavanty etān
viṣṇu-pakṣān ivāsurāḥ
Demons cannot harm the demigods, who always have Lord Viṣṇu on their side. Similarly, any person or group attached to all-auspicious Kṛṣṇa cannot be defeated by enemies.
