This looks pretty much like the 'classic' 7 Days Course that was taught through the 70s and 80s. I understand that these days they have split it up into a non-specific introductory course and then an Advance Course for potential encultees. In the old, old days they used to have people actually stay for 7 days, back then it was 7 hour long lessons, then a Murli (... if the student made it through to the end which few actually did!).
Perhaps you mean the Advance Course of the PBKs (also known as AIVV)?
It takes the standard BK lessons but offers an explanation of them, and the Murlis, at a greater depth or metaphorical level (from a PBK point of view ... and probably does from a purely objective point of view). The BKs tell their students it is extreme Maya or evil and threaten to disbar any that go and study it ... ... although their leaders have in private and have adopted parts of it from time to time).
It does contains some truths, and offers some insights into the BK world that the BKs don't, but it does not challenge the basic premise of the BKWSU, e.g. 5,000 years, Destruction etc.
