Prabhupada: History, it is not a new movement. You have seen this book. You read that book thoroughly. You will get full knowledge. This movement is very, very old and standard. It is never changed. As soon as you change it, then the potency of the movement is lost.
Faill: Sorry, what was that?
Prabhupada: Potency. Just like electricity. There is standard
regulation: "This is negative; this is positive. You must act like this. You must fix like..." You cannot do whimsically: "No, why not this way? Why not that way?" Then it is lost. Then there will be no electricity. Similarly, there is standard method how to understand this philosophy, how to get it, I mean to say, what is called, authoritatively. Then it will act.
(S.P.Room Conversation with Bill Faill (reporter)October 8, 1975, Durban)
Note: Due to the offensive changes made to Srila Prabhupada's original transcendental books, (click here to see articles) by the pseudo Krishna cult leaders, the potency of ISKCON is now lost
This movement manifesting itself as Srila Prabhupada's ISKCON is actually a sinister movement outside the Parampara (apa-sampradaya)
The standard method how to understand the Krishna Consciousness philosophy authoritatively, is to hear from Srila Prabhupada in the form of his original books and lecture tapes. THEN IT WILL ACT !
If we hear from the mayavadi's and sahajiya's within the pseudo-Krishna cults such as Iskcon and the Gaudiya Matha, then we will be doomed !
If a avaisnava, if a Mayavadi, he speaks about Bhagavatam or Bhagavad-gita, one should not hear it. He should avoid it because it will create some misimpression. Caitanya Mahaprabhu has forbidden strongly, mayavadi-bhasya sunile haya sarva-nasa: "If one hears from a Mayavadi about Bhagavad-gita, Srimad-Bhagavatam, then that person is doomed." So this is, therefore, tad-vijnanartham sa gurum evabhigacchet. This injunction means one should approach a Vaisnava to accept him as guru and then take lessons from him and make his life successful.

(Srimad-Bhagavatam Lecture 3.26.27 Bombay, January 4, 1975)
Note: The injunction is to approach Srila Prabhupada and accept him as guru and then take lessons from him (original books and tapes) and make our life successful.
"Whatever progress we have made, it is simply to distributing these books......Practically, books are the basis of our Movement. Without our books, our preaching will have no effect."
Whatever progress we have made, it is simply to distributing these books. So go on, and do not divert your mind for a moment from this.
(S.P.L. to Ramesvara dasa 11/10/74)
My first concern is that my books shall be published and distributed profusely all over the world. Practically, books are the basis of our Movement. Without our books, our preaching will have no effect.
( Letter to: Mandali Bhadra 20 January, 1972)
Note: Srila Prabhupada's original books are the basis of the real ISKCON. Without these transcendental books no preaching by various reform groups will have any effect.
Also if these reform movements continue to distribute the changed (milk touched by the lips of a serpent) books and use the laxmi that they collect to print more, then they are fully implicated in this second poisoning of the Acarya Srila Prabhupada and will be punished along with the pseudo-Krishna cult leaders.
This rascal changing of the Acarya's words is murder and anyone who after hearing about this great blasphemy doesn't use whatever he has in his possession, namely his life, words, wealth, or inteligence to fight against it, is also subject to hellish reactions.
One who hears blasphemy of the Supreme Personality of Godhead or His devotees should immediately take action or should leave. Otherwise he will be put into hellish life perpetually. There are many such injunctions. Therefore as a regulative principle one should not be unfavorable toward the Lord but always favorably inclined toward Him.
(S.B. 7.1.26)
Just like Prahlada Maharaja. Prahlada Maharaja was standing, and his father was being killed. Is it a very good thing? Suppose if I am here and somebody kills me, and if you do not protest, is it a very good business? People will be surprised that "So many disciples are there, and this man is being killed, and nobody do anything?"
(Srimad-Bhagavatam Lecture 1.8.47  Mayapura, October 27, 1974)
So we are simply surprised that so many disciples are here and Srila Prabhupada is being KILLED AGAIN and hardly any of them are doing anything !!!
We have had practical experience of only one poor fallen grhastha been instrumental in printing 7,500 original 1969 Sri Isopanisads. If the staunch leaders of the various reform movements also take up the task of saving the life and soul of ISKCON, namely Srila Prabhupada in his Vani form, then we will see amazing results !
If these reform leaders don't do this then it is lost, and all their false advertisments promising reform is simply another form of cheating !
"if you do not do this, then it is lost."
Prabhupada: When it was not handed down. Simply understood by speculation.  Or if it is not handed down as it is. They might have made some changes.Or they did not hand it down. Suppose I handed it down to you, but if you do not do that, then it is lost. Now the Krsna consciousness movement is going on in my presence. Now after my deparature, if you do not do this, then it is lost. If you go on as you are doing now, then it will go on. But if you stop... (end)
