Srimad-Bhagavatam: Canto 10 - Chapter 1 - Verse 41
Sanskrit:
नूनं भगवतो माया योगिनामपि मोहिनी ।यद् वयं गुरवो नृणां स्वार्थे मुह्यामहे द्विजा: ॥ ४१ ॥
ITRANS:
nūnaṁ bhagavato māyāyoginām api mohinīyad vayaṁ guravo nṛṇāṁsvārthe muhyāmahe dvijāḥ
Translation:
The illusory potency of the Supreme Lord certainly bewilders even the great mystics, what to speak of us. As brāhmaṇas we are supposed to be the spiritual masters of all classes of men, yet we have been bewildered about our own real interest.
