Hari Sauri: Srila Prabhupada's godbrother B. R. Sridhara Swami came in Prabhupada's car from his matha in Navadvipa. He stayed for most of the afternoon. He and Prabhupada took prasadam together on the veranda. Srila Prabhupada had him stay in the room right next to his own, and after a light rest, they talked for most of the afternoon.
During their conversations they exchanged reports on each other's preaching activities. Srila Prabhupada told me afterward that Sridhara Maharaja had said that he regarded him as the real acharya. Sridhara Maharaja told him that Lord Chaitanya had given His prediction that the chanting of the Holy Name would go to every town and village, but he and his godbrothers had not taken this statement literally. Now by Srila Prabhupada's efforts he said he could understand its real meaning.
