PART OF LECTURE: ... "Vaisnava aparadha is a great offense. You know Ambarisa Maharaja. He was a devotee, and he Durvasa, he was very proud of his yogic power, and he committed offense at the feet of Ambarisa Maharaja, and he was punished by Krsna by sending the sudarsana-cakra. And he wanted help from so many, Brahma, Visnu. He could go directly to the Visnuloka, but he was not pardoned.
He had to come to Vaisnava, Ambarisa Maharaja, fall down at his lotus feet. And he, of course, Vaisnava, immediately excused him. So Vaisnava aparadha is great offense, hati-mata. So we should be very careful about Vaisnava aparadha. We should not Arcye visnu sila-dhir gurusu nara-matir vaisnava-jati-buddhih.
The vaisnava-jati-buddhih is also another offense, great offense. Similarly, to think of guru as ordinary human being, that is also offense. To think of Deity as made of metal, stone, that is These are offenses. Sa naraki. So we should be very careful about the regulative principles and follow the footprints of Vaisnava. Mahajano yena sa gatah. Don't think that Prahlada Maharaja is ordinary boy. We should learn from Prahlada Maharaja how to advance in devotional service.
[PADA NOTE: This has been the whole problem since 1977, the leaders of ISKCON have been saying that gurus are even worse than the ordinary man, because -- gurus fall down into illicit sex, drugs, criminal actions and so on.
In other words, the leaders of ISKCON are not advanced enough to promote the worship of ordinary men, instead they find very degraded people to become their gurus. Notice the warning here -- "Sa Naraki." -- "Anyone who says gurus are ordinary men, are residents of Narakah, or hell."
No wonder the GBC gurus do not like PADA, we have reminded them of this warning since 1977, gurusuh narah matih -- narakah sah, its a severe offense to say gurus are ordinary and fallen, what to speak of debauchees -- as the GBC gurus seem to be falling into on a regular basis. ys pd]
