It is interesting to see how many times the BKWSU has changed there story. That should be a warning enough to non-Bks and newcomers. But I don't think "A Brief Biography of Brahma Baba" by Jagdish Chander counts as "evidence" of facts.
It only counts as evidence of the Brahma Kumaris comic and amateur historical revision and a confusion of the facts. In particular, Jagdish Chander's romantic fictionalisation of his guru. I am sorry to say this directly but small part of PBKism involves stirring up and confusing "The Knowledge", fact and fiction even further.
The Om Radhe book, because it is largely a copy of court papers and legal correspondence which I suspect Lekhraj Kripalani's counsel would not risked falsifying, remains our best starting point for fact.
And, from that, Lekhraj Kripalani was 54 in 1938. "56" would be in 1940. There was no God Shiva until after 1950.
We know know that there was no knowledge and no mention of Shiva Baba in the BKWSU until after 1950 when it first arises. No one, neither the BKs nor Virendra Dev Dixit and the PBKs, have been able to account for how and why it all came about. I know the approximate PBK version. I know you are trying to covertly suggest "ShivBaba" in the case was someone else, e.g. Lekhraj Kirpalani's partner Narian Shewakram.
But, honestly, you cannot fill a couple of lines in "A Brief Biography of Brahma Baba" by Jagdish Chander with such significance.
Why don't the PBKs just go and find Narian Shewakram family, check with the records and pull out the real facts. And why does not Virendra Dev Dixit know them? I suspect even in the records of the Royal families and the Indian/Sindhi government, you will find more solid information.
If someone can pay my airfare to India and help me there, I will go and find it myself. I don't believe the truth is hard to find.
