Suresvara das: The next day was Vyasa-puja and Srila Prabhupada, being very sensitive to the time, place and circumstance, gave this wonderful Vyasa-puja address to describe the spiritual master and why the spiritual master is being offered so much honor and homage on this day because, after all, there were many people there, scholars and journalists, etc., who were not familiar with this etiquette.
So Srila Prabhupada said, “Krishna is very big, He’s a very big person.” And Prabhupada said, “Just like in this material world, if you want to please or even see a big man, it is very difficult to do.” He often used Ford and Rockefeller. So he said, “Just like Mr. Ford, if you want to please Mr. Ford, it’s very hard or even to see him is very hard. But if you happen to see Mr. Ford walking his dog and you give Mr. Ford’s dog a two-cent lozenge,” Prabhupada used the word lozenge, “then Mr. Ford is very easily pleased.”
So Prabhupada said, “I am the dog of God. It is very difficult to approach Krishna. But if you simply please His dog, Krishna will be pleased.”
