When Srila Prabhupada first began lecturing in New York in 1966, he would often attack the Mayavadi impersonalists in his talks, and not understanding this I joked with friend: "Mayavadi? When was the last time you saw a Mayavadi?" None of us could understand who Srila Prabhupada was talking about; we all thought that the Mayavadis were a little group of philosophers in India against whom Srila Prabhupada was waging theologic battle. But actually we were all Mayavadis.
