A second look at the video in which the nun came face to face with the Dalai Lama and handed him a message from the Western Shugden Committee, while requesting gently for freedom of religion for Shugden practitioners, shows up more telling details. There was a security team with the Dalai Lama; but, when his private security urged him to leave, the Dalai Lama came back to address the nun directly , pointed his finger at her, and said "No "several times. He also went on to say: "This is not religion. I know the Buddha's teaching. This is worship of a spirit".
In lieu of this, I see the whole scene differently from what Norbu has portrayed here. It is not a nun aggressively threatening the Dalai Lama and endangering him by her aggressive approach. It is rather a much needed direct peaceful appeal, by a gentle nun, to the Dalai Lama to lift the ban, after all other peaceful efforts to request a peaceful meeting with Dalai Lama to seek his views ,discuss and negotiate the lifting of the ban had failed.
Meanwhile, every failed attempt to meet the Dalai Lama, every failed attempt to peacefully negotiate the lifting of the ban, means more and extended suffering for the poor Shugden practitioners, especially in India, who have suffered long and terribly from the violent actions and harsh measures taken against them by the Tibetan government and their supporters since the imposition of the ban.
The Western Shugden members had no other recourse. This one opportunity was the best. The Western and international media were present. The world would now know about the terrible consequence of the enforcement of the ban on Shugden. The world would now understand why the ban on Shugden practice has to be lifted. The West which respects freedom of religion would surely now sympathize with the cause of Shugden practitioners to have the ban lifted quickly.
So there is no question that the Western Shugden nun did the right thing to give a voice to the cause of lifitng of the ban, for the sake of Shugden practitioners,who have suffered in silence all this while.
Yet I am not saying anything against the Dalai Lama, for I know he is Chenrezig and his seemingly unacceptable behavior and speech against Shugden, including his ban on Shugden, are things which I believe will be explained when the right time comes for them to be explained.
