Yes prabhu I also heard that the Gaura govinda maharaja program broke away from ISKCON, thinking that GGM had been poisoned by some of the GBC's making a plot to remove him. And we also heard a number of his follower ran off to the GBC's hand maiden / cheer leader / shiksha guru / rasika adviser Narayan Maharaja.
Gaura Govinda maharaja was saying he was going to create a mass public protest of the GBC using the local brahmanas in Maypura area. He said he was going to have them protest that the GBC says we originated in Krishna's leela, whereas GGM said -- we did not originate with Krishna.
Ooops, except Srila Prabhupada says that the Gaudiya Matha / local brahmanas are tinged with mayavada because they do not understand that we originated with Krishna in His leela. Anyway, some think that GGM's blatantly claiming he would make a mass protest of the GBC is why he was allegedly poisoned. Same thing with Suhotra, he was saying he was going to help make a protest of some GBC programs, and he died right after that. Some think he was poisoned, and so on and so forth. As for this samadhi, its unclear if they ever owned the land that this samadhi was on in the first place. ys pd
