I just want to say that I'm not here to badmouth Bhaktivedanta Svamiji or Bhaktisiddhanta, I went through that phase some years ago and for a while I admit when I first found out about IGM not having a proper Guru-parampara as is recognized in orthodox Gaudiya Vaishnavism, i.e. going back in an unbroken diksha line to one of the associates of Sri Chaitanya.
I have since gotten over some of my bitterness (I hope) and see things in a different light, meaning I honor all my spiritual teachers that have blessed me in this life even though I may disagree with them on certain points.
The stories of Bhaktisiddhanta being kicked out of Bhaktivinodes home and Puri were told to devotees primarily by Lalita Prasad as he was a direct witness and saw 1st hand.
Now some accept Lalitas Prasads version others accept Bhaktisiddantas and never shall the twain meet it seems.
I for one accept Lallita Prasads version and have for many years, decades in fact. The pieces of the puzzle just fit, Lalita Prasad got diksha from Bhaktivinode, Bhaktisiddhanta did not, so therefore he could not pass that line of diksha down to Gaudiya Math.
Also the fact that Sannyas was never before seen in the Gaudiya Sampradaya before Gaudiya Math or 'brahmin initiation', and so many things that Bhaktisiddhanta introduced that were never there before seems was his replacement for not having received diksah from his father and he paved a new road of sorts.
However this is not to say that his or GM and Bhaktivedanta Svamijis efforts were not worthwhile and didn't benefit people spiritually and put them on the path of Krishna Bhakti (I believe they did).
I recommend cbrahma read from Jagats article that he quoted from earlier the section on "The Gaudiya Math after Bhaktisiddhantas Death' which gives much history in this regard as well as other articles by Jagat who really is one of the foremost scholars of Gaudiya Vaishnavism today in the western world (although he's been in India for some months now).
namaskar,
jijaji
