Indradyumna Swami: In the summer of 1971, Indradyumna dasa accompanied Srila Prabhupada on his flight to London, where he was to attend the Ratha-yatra festival. On the flight, a film was shown - an old silent film of Charlie Chaplin. When the film began, Indradyumna dasa began reading the Bhagavad-gita, but he noticed that Srila Prabhupada, who was sitting two seats away, was watching the film and chuckling.
Indradyumna felt a little confused, since he knew devotees were not supposed to watch movies, but seeing Prabhupada's appreciation of the film, he stopped reading and laughed along with Prabhupada and his servant at Charlie Chaplin's humor. When the film was over, Indradyumna met Pradyumna dasa at the back of the plane and asked why Srila Prabhupada was laughing during the film. Pradyumna said he would go and ask Prabhupada. He soon returned smiling and said, "Prabhupada said that Krishna is the original source of everything, and since Charlie Chaplin's humor was original, he could appreciate Krishna there." Indradyumna returned to his seat, appreciating how Srila Prabhupada saw Krishna everywhere.
