Nanda Kumar : Once I gave Prabhupada something with fresh boysenberries. He said, "Oh, this is very good. What is this?" I said, "That's called boysenberries. It's a cross between a couple of different kinds of berries by a man named Boysen."
Prabhupada said, "It is very good. Poison berry?" I said, "No, sir, boysenberry." He laughed. He was joking. So I told the devotees that story. It was one of Prabhupada's lighthearted joking moods. Sometime later, boysenberries were in the kitchen, and one of the matajis said, "You can't offer those, they're poisonous. Prabhupada said they're poisonous." I told Prabhupada, "You joked with me about boysenberries and poison berries, and now the story is out that boysenberries are poisonous."
He laughed and said, "Everyone is saying, 'Prabhupada has said this, and Prabhupada has said that,' but I've never said. Believe what you read in my books and what you hear me speak, and take everything else with a grain of salt."
