If you have not yet had the chance to read Helmut Gassner's speech at the Friedrich-Naumann-Foundation Hamburg, on March 26th 1999, it is well worth doing so.
Helmut Gassner is a long-term Western Buddhist monk, scholars and practitioner, and he was the interpreter (and chauffeur) for the Dalai Lama for 17 years. He has a unique inside understanding of the Dalai Lama's motives and so on, and personally knew all the original players in this drama.
According to a contemporary:
"Of those of us who had gathered around and subsequently left Geshé Rabten, the outstanding exception was Helmut Gassner. He stood loyally by Geshé and retains his robes to this day. He spends his time between the center in Switzerland and Trijang Labrang in Feldkirch, Austria. Helmut is notable for wading into the shocking Dorje Shugden scandal with his courageous speech to the Friedrich-Naumann Foundation in 1999."
