I like how the story was told in the article. It started off with the illness of His Holiness the 98th Ganden Tripa, and along with it, his title, fame, popularity and recognition of being a great lama, and representation of the incomparable Lama Tsongkhapa on Earth. Then it proceeds to talking about Gen Nyima, a humble, holy and highly attained monk, who wanted to practice and gain attainments in solidarity. And although his only wish was that, when people approached him for help and advise, he would do all he can to help. Such compassion.
So then you see how 2 compassionate lamas are brought and tied in together. One manifesting illness to teach others, the other teaching others through humility. Amazing. And how DS is introduced, as being the only one that can save H.H. Shows how powerful Dorje Shugden is, as Gen Nyima has not practised DS all his life, nor is he interested in doing any other pujas but perfecting Yamantaka's practises, but through divination results, recommended 3 days of DS Puja to save the life of H.H. There is nothing that Gen Nyima can gain in "promoting" DS this way - so this only proves how efficacious DS is in today's society.
Now with Tashi, the teaching from this story goes to show that even as a sangha member, he cannot really let go of confining with society's ideals. For him, choosing face was more important than his guru. No doubt he will reap the terrifying consequences of his actions, but it shows that if it is this hard for even a sangha member, who has taken on vows, to practice renouncing the 8 wordly concerns, then it is much more difficult for one still in samsara, to practise the same. That being said, it doesn't mean it is impossible. It is sad that Tashi did what he did.. literally, his guru died in his hands.
