Ironically, i think that the Dalai Lama only gained fame after he became exiled from TIbet. With no disrespect to the Dalai Lama, who i do think is a holy monk, he became the poster boy for the "poor victim of China". With the gradual transfer of power over the past few decades from the west to China, the world is using the Dalai Lama as a bargaining tool against China. The Dalai Lama's Nobel Peace prize, for example, was i believe only given to the Dalai Lama as a protest against China.
All this media coverage of the Dalai Lama to date has served to elevate the Dalai Lama to a world icon. As a result, many non-Tibetans began to think that the Dalai Lama's word is unquestionable, so when the Dorje Shugden ban came about, people accepted it as gospel without question.
While most people see the Dalai Lama as a holy person, they do not realise that the Dorje Shugden ban is just political, even though the Dalai Lama has stepped down as the temporal head of the Tibetan diaspora. It will be interesting to see how this complicated situation is resolved by one of the world's most popular leaders, the Dalai Lama.
