Srimad Bhagavatam Canto 06, Chapter 07, Text 11

SB 6.7.11

aho bata mayasadhu
 krtam vai dabhra-buddhina
yan mayaisvarya-mattena
 guruh sadasi katkrtah
 
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada: 
 
Alas, what a regrettable deed I have committed because of my lack of intelligence and my pride in my material opulences. I failed to show respect to my spiritual master when he entered this assembly, and thus I have insulted him.
