Srimad Bhagavatam Canto 10, Chapter 23, Text 41

SB 10.23.41

nunam bhagavato maya
 yoginam api mohini
yad vayam guravo nrnam
 svarthe muhyamahe dvijah
 
Translation: 
 
The illusory potency of the Supreme Lord certainly bewilders even the great mystics, what to speak of us. As brahmanas we are supposed to be the spiritual masters of all classes of men, yet we have been bewildered about our own real interest.
