Rupa-Vilasa: Prabhupada came to Dallas three or four times and he used to take walks on White Rock Lake, the richer section, where a famous oil tycoon, H. L. Hunt, had a home. The devotees told Prabhupada, “We tried to see H. L. Hunt but he wouldn’t see us.” Prabhupada said, “Oh? He would not see you? But when death comes, will he also say, ‘I cannot see you’? Anyway, he may say, but death will come and do his business.” Then Prabhupada said, “What would you have said if you were able to see him?” Somebody said, “We would show him your books.” Prabhupada said, “No.” “We’d tell him about the school.” Prabhupada said, “No.” He didn’t like those answers. Finally Prabhupada said, “You should tell him he has become a wealthy man by stealing from the earth and at death he will be severely punished for this crime.” A devotee said, “Prabhupada, if we speak to him like this, he’ll become angry.” Prabhupada said, “Angry? If I shake my stick at a dog, he will also become angry. You have to learn how to talk to this class of men.”
