1) Johnson's books are copyrighted and they were copyrighted at the
time of their publication (the 1930s); and, as I am informed, the
copyright has been updated.
2) Charan Singh in 1970 explicitly stated that he was aware of
Twitchell's plagiarism in a question/answer session during his last
tour of the United States (refer to the book Thus Saith the Master).
3) Kirpal Singh, and his several successors were also keenly aware of
Twitchell's plagiarism. Indeed, I had a very long conversation with
the late Sant Darshan Singh - Kirpal's son - about the issue.
4) My sense is that Beas does not want to litigate over this issue,
since they are not publishing Johnson's books for a profit (all books
are sold at cost). This does not mean that Beas may not be forced to
do something about this legally in the future. I do know that they
have been advised numerous times by various parties to do something
legally about the issue.
5) Knowing the late Charan Singh, he always liked to avoid legal
proceedings--being trained as a lawyer himself--since they most often
cause more harm than good (and cost people thousands of dollars).
6) I should also mention, though this is the first time I have stated
this publicly--that several shabd yoga masters in India have read the
Making of a Spiritual Movement, including the late Sant Darshan Singh,
Maharaj Charan Singh, Baba Faqir Chand, S.D. Maheshwari, and others.
7) Each of them agreed that Twitchell had inappropriately copied huge
sections from Johnson's several books.
8) It would be interesting to see what the present shabd yoga gurus
think about Eckankar's nefarious activities. I have not talked to any
of them about it.
Hope this helps, albeit slightly.
