…just like in our ISKCON there are so many false things: “Prabhupāda said this, Prabhupāda said that.”
(Letter to: Krsna dāsa—Vrndāvana 7 November, 1972)

Prabhupāda: Yes, preaching, preaching, you will become perfect preacher. Preach only what you have heard from Krsna and guru, that’s all. Don’t add and subtract. Then you are secure. And if you add some concoction just like somebody says that “I may do whatever I like independently. If I chant, then everything is all right,” this is nonsense addition. It is not the fact. That is the danger. Some inexperienced man, he introduces some concoction. Sometimes they say, “Prabhupāda said it.” More misleading. Yes. (Morning Walk—February 3, 1975, Hawaii)

Prabhupāda: So, when you change, then the authority is lost. Just like in our society, sometimes they do something nonsense and they say, “Prabhupāda said.” (laughter) They are doing that. We know that. It is deteriorated like that. Therefore Krsna said, sa kaleneha mahata yogo nastah kaunteya: “And in due course of time, this yoga was lost. Therefore I am repeating the same thing, old philosophy to you.” So it requires like that.

(Room Conversation with Carol Cameron—May 9, 1975, Perth)

“Unless it is there from me in writing, there are so many things that ‘Prabhupāda said.’”
