Well, of course I lack the knowledge. That's why I'm asking question Prabhu. Isn't it?
If you claim the sources you've pointed out does show indeed dealt with the arguments shown here, I suppose we should give them a close look. On the other hand: If the pro-ritvik propagators here indeed gave these sources a closer look, and if these sources do have an indisputable answer to some very irrelevant questions, I still don't understand why the best argument I've heard so far is that I should just "accept the ripe mango handed to me" no question ask…
Anyway, from what I read in Prabhupadas books, he indeed talks about a system of guru-parampara, a chain of guru-disciple system beginning in the lord himself. In that chain, Prabhupada is the disciple of his guru, just like to his disciples Prabhupda is the guru. "a disciple of my disciple". This chain, as I understand, goes back to vedic time and THAT is status quo. Unless, of course, there is an instruction where Prabhupada literally states: "The parampara ends with me!". I expect to find such a quote in the sources offered here. Otherwise, this just makes Prabhupadas instructions for him as the one diksa guru an instruction for the time of his physical presence and the ritvik system, introduced by him, as an instruction for the times where his physical condition wouldn't allow him to travel.
BUT! If all is correct, and Prabhupada indeed instructed that the parampara ends with him, we now have to deal with a bigger problem: did Prabhupada diverted from the Gaudia-Vaishnava tradition and from Vedic tradition…
