Srimad Bhagavatam Canto 10, Chapter 80, Text 44

SB 10.80.44

sri-brahmana uvaca
kim asmabhir anirvrttam
 deva-deva jagad-guro
bhavata satya-kamena
 yesam vaso guror abhut
 
Translation: 
 
The brahmana said: What could I possibly have failed to achieve, O Lord of lords, O universal teacher, since I was able to personally live with You, whose every desire is fulfilled, at the home of our spiritual master?
 
Purport: 
 
Sudama Brahmana wisely understands his extraordinary good fortune of having lived with Sri Krsna at the residence of their spiritual master. Thus whatever external difficulties they experienced were actually an expression of the Lord’s mercy, to teach the importance of service to the spiritual master.
 
Srila Prabhupada renders the learned brahmana’s feelings as follows: “[Sudama said:] ‘My dear Krsna, You are the Supreme Lord and the supreme spiritual master of everyone, and since I was fortunate enough to live with You in the house of our guru, I think I have nothing more to do in the matter of prescribed Vedic duties.’”
