Srimad Bhagavatam Canto 10, Chapter 80, Text 31

SB 10.80.31

kaccid gurukule vasam
 brahman smarasi nau yatah
dvijo vijñaya vijñeyam
 tamasah param asnute
 
Translation: 
 
My dear brahmana, do you remember how we lived together in our spiritual master’s school? When a twice-born student has learned from his guru all that is to be learned, he can enjoy spiritual life, which lies beyond all ignorance.
