aho bata mayasadhu
krtam vai dabhra-buddhina
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.
