Tranakarta : Once Jagadish, a few other devotees and I were in Prabhupada's room when Prabhupada was speaking in Hindi with some big political guests. It was ecstasy seeing Prabhupada's exchanges with these people but we couldn't understand anything. When it was time for them to leave, Prabhupada graciously walked them to the door and in English one of the guests said something to Jagadish. Jagadish replied, "Accha," in the same way that all the devotees say, "Accha." Prabhupada said, "Just see, he's speaking Hindi!" Everybody in the room busted up with laughter.
