Srila Prabhupada KNEW these ROGUES inside out and he WARNED us about them:
SB 4.28.48 P Puranjana Becomes a Woman in the Next Life:
Whenever an acarya comes, following the superior orders of the Supreme Personality of Godhead or His representative, he establishes the principles of religion, as enunciated in Bhagavad-gita. Religion means abiding by the orders of the Supreme Personality of Godhead. Religious principles begin from the time one surrenders to the Supreme Personality of Godhead.
It is the acarya’s duty to spread a bona fide religious system and induce everyone to bow down before the Supreme Lord. One executes the religious principles by rendering devotional service, specifically the nine items like hearing, chanting and remembering.
UNFORTUNATELY, WHEN THE ACARYA DISAPPEARS, ROGUES AND NONDEVOTEES TAKE ADVANTAGE AND IMMEDIATELY BEGIN TO INTRODUCE UNAUTHORIZED PRINCIPLES IN THE NAME OF SO-CALLED SVAMIS, YOGIS, PHILANTHROPISTS, WELFARE WORKERS AND SO ON.
Actually, human life is meant for executing the orders of the Supreme Lord, and this is stated in Bhagavad-gita (9.34):
man-mana bhava mad-bhakto
mad-yaji mam namaskuru
mam evaisyasi yuktvaivam
“Engage your mind always in thinking of Me and become My devotee. Offer obeisances and worship Me. Being completely absorbed in Me, surely you will come to Me.”
"The main business of human society is to think of the Supreme Personality of Godhead at all times, to become His devotees, to worship the Supreme Lord and to bow down before Him. The acarya, the authorized representative of the Supreme Lord, establishes these principles, but when he disappears, things once again become disordered. The perfect disciples of the acarya try to relieve the situation by sincerely following the instructions of the spiritual master. At the present moment practically the entire world is afraid of rogues and nondevotees; therefore this Krsna consciousness movement is started to save the world from irreligious principles. Everyone should cooperate with this movement in order to bring about actual peace and happiness in the world.
The Lord states that as soon as one reaches Him by devotional service--which is the one and only way to approach the Personality of Godhead--one attains complete freedom from the bondage of birth and death. In other words, the path of salvation from the material clutches fully depends on the principles of knowledge and detachment gained from serving the Lord.
THE PSEUDO RELIGIONISTS HAVE NEITHER KNOWLEDGE NOR DETACHMENT FROM MATERIAL AFFAIRS, FOR MOST OF THEM WANT TO LIVE IN THE GOLDEN SHACKLES OF MATERIAL BONDAGE UNDER THE SHADOW OF PHILANTHROPIC ACTIVITIES DISGUISED AS RELIGIOUS PRINCIPLES. BY A FALSE DISPLAY OF RELIGIOUS SENTIMENTS, THEY PRESENT A SHOW OF DEVOTIONAL SERVICE WHILE INDULGING IN ALL SORTS OF IMMORAL ACTIVITIES. IN THIS WAY THEY PASS AS SPIRITUAL MASTERS AND DEVOTEES OF GOD.
Such violators of religious principles have no respect for the authoritative acaryas, the holy teachers in the strict disciplic succession. THEY IGNORE THE VEDIC INJUNCTION ACARYOPASANA--“ONE MUST WORSHIP THE ACARYA”--AND KRSNA’S STATEMENT IN THE BHAGAVAD-GITA (4.2) EVAM PARAMPARA-PRAPTAM, “THIS SUPREME SCIENCE OF GOD IS RECEIVED THROUGH THE DISCIPLIC SUCCESSION.” INSTEAD, TO MISLEAD THE PEOPLE IN GENERAL THEY THEMSELVES BECOME SO-CALLED ACARYAS, BUT THEY DO NOT EVEN FOLLOW THE PRINCIPLES OF THE ACARYAS.
These rogues are the most dangerous elements in human society. Because there is no religious government, they escape punishment by the law of the state. They cannot, however, escape the law of the Supreme, who has clearly declared in the Bhagavad-gita that envious demons in the garb of religious propagandists shall be thrown into the darkest regions of hell (Bg. 16.19-20).
SRI ISOPANISAD CONFIRMS THAT THESE PSEUDO RELIGIONISTS ARE HEADING TOWARD THE MOST OBNOXIOUS PLACE IN THE UNIVERSE AFTER THE COMPLETION OF THEIR SPIRITUAL MASTER BUSINESS, WHICH THEY CONDUCT SIMPLY FOR SENSE GRATIFICATION.
Madhya 1.218 The Later Pastimes of Lord Sri Caitanya Mahaprabhu
Srila Narottama dasa Thakura says, chadiya vaisnava seva nistara payeche keba: unless one serves a Vaisnava, he cannot be delivered. The spiritual master initiates the disciple to deliver him, and if the disciple executes the order of the spiritual master and does not offend other Vaisnavas, his path is clear. Consequently Sri Caitanya Mahaprabhu requested all the Vaisnavas present to show mercy toward the two brothers, Rupa and Sanatana, who had just been initiated by the Lord.
When a Vaisnava sees that another Vaisnava is a recipient of the Lord’s mercy, he becomes very happy. Vaisnavas are not envious. If a Vaisnava, by the mercy of the Lord, is empowered by Him to distribute the Lord’s holy name all over the world, other Vaisnavas become very joyful--that is, if they are truly Vaisnavas. One who is envious of the success of a Vaisnava is certainly not a Vaisnava himself, but an ordinary mundane man. Envy and jealousy are manifested by mundane people, not by Vaisnavas.
Why should a Vaisnava be envious of another Vaisnava who is successful in spreading the holy name of the Lord? An actual Vaisnava is very pleased to accept another Vaisnava who is bestowing the Lord’s mercy. A MUNDANE PERSON IN THE DRESS OF A VAISNAVA SHOULD NOT BE RESPECTED BUT REJECTED. THIS IS ENJOINED IN THE SASTRA (UPEKSA). THE WORD UPEKSA MEANS NEGLECT. ONE SHOULD NEGLECT AN ENVIOUS PERSON. A preacher’s duty is to love the Supreme Personality of Godhead, make friendships with Vaisnavas, show mercy to the innocent and reject or neglect those who are envious or jealous.
There are many jealous people in the dress of Vaisnavas in this Krsna consciousness movement, and they should be completely neglected. THERE IS NO NEED TO SERVE A JEALOUS PERSON WHO IS IN THE DRESS OF A VAISNAVA. WHEN NAROTTAMA DASA THAKURA SAYS CHADIYA VAISNAVA SEVA NISTARA PAYECHE KEBA, HE IS INDICATING AN ACTUAL VAISNAVA, NOT AN ENVIOUS OR JEALOUS PERSON IN THE DRESS OF A VAISNAVA.
Bg 4.42 P Transcendental Knowledge
A bona fide spiritual master is in the disciplic succession from time eternal, and he does not deviate at all from the instructions of the Supreme Lord as they were imparted millions of years ago to the sun-god, from whom the instructions of Bhagavad-gita have come down to the earthly kingdom. One should, therefore, follow the path of Bhagavad-gita as it is expressed in the Gita itself AND BEWARE OF SELF-INTERESTED PEOPLE AFTER PERSONAL AGGRANDIZEMENT WHO DEVIATE OTHERS FROM THE ACTUAL PATH. The Lord is definitely the supreme person, and His activities are transcendental. One who understands this is a liberated person from the very beginning of his study of the Gita.
Bg 16.4 P The Divine And Demoniac Natures
In this verse, the royal road to hell is described. The DEMONIAC WANT TO MAKE A SHOW OF RELIGION AND ADVANCEMENT IN SPIRITUAL SCIENCE, ALTHOUGH THEY DO NOT FOLLOW THE PRINCIPLES. THEY ARE ALWAYS ARROGANT or proud in possessing some type of education or so much wealth. THEY DESIRE TO BE WORSHIPED BY OTHERS, AND DEMAND RESPECTABILITY, ALTHOUGH THEY DO NOT COMMAND RESPECT. Over trifles they become very angry and speak harshly, not gently. They do not know what should be done and what should not be done. THEY DO EVERYTHING WHIMSICALLY, ACCORDING TO THEIR OWN DESIRE, AND THEY DO NOT RECOGNIZE ANY AUTHORITY.
Pusta Krsna: Some of them will say some things that Krsna says, but they’ll take from other places also. What is the position of such persons?
Prabhupada: He’s most dangerous. HE’S MOST DANGEROUS. HE IS OPPORTUNIST. HE’S FINDING OUT CUSTOMER, something here… According to the customer he is giving something, as the customers will be pleased. So he is not guru. He’s a servant. He wants to serve the so-called disciples so that he may be satisfied and pay him something. He’s servant. He’s not guru. Guru is the master.
You cannot disobey guru. But if you become a servant, you want to please the disciple by flattering him to get his money, then you are not guru, you are servant. Just like a servant pleases the master. He’s not guru. He’s servant. So our position should be servant, yes, but servant of the Supreme. So guru means heavy. You cannot utilize him for satisfying your whims. That is not guru.
