Badrinarayana : An Indian professor said that it was all one. Prabhupada explained that it is not all one, that there are differences. Prabhupada said, "If I say cotton ball or cotton shirt, is there a difference?" The man said, "Ah, cotton ball, cotton shirt. . . ." Prabhupada said, "If I say cotton ball or cotton shirt, is there a difference?" The man said, "Ah, cotton is . . ." Prabhupada said it three or four times. He was sitting behind a low table, and the man was sitting on the other side. Prabhupada reached over, grabbed the man by the shirt, shook him and said, "If I say cotton ball or cotton shirt, is there a difference?" The man got it. He didn't just get it to be polite, but Prabhupada, while still friendly, managed to shake through his buffalo brain. The man understood that there was a difference between a cotton ball and a cotton shirt. However, after the man left, Prabhupada pointed out, "This is the special sanction of old men and little children. They can go anywhere, and they can say anything. You cannot imitate."
