Grandmapele,
I understand this controversy has made things difficult for both sides, so I do understand where some of these people criticizing Kelsang Gyatso Rinpoche are coming from, it is just that many of the criticisms are not just pointless but they're not even true.
For example, there is an image on the cover of the new book of Guru Sumati Buddha Heruka. The critic says that this image is a painting of Kelsang Gyatso Rinpoche, that it is inauspicious to paint a Guru on a lotus if they are still alive, and so on. I am close friends with the artist that made this painting and know the truth. The image is not Kelsang Gyatso Rinpoche, it is Guru Sumati Buddha Heruka. The artist, who is very experienced in the Dharma, wanted to paint him very youthful, and she is well known for painting quite youthful aspects of holy beings. That the face of Guru Sumati Buddha Heruka bears resemblance to Kelsang Gyatso Rinpoche truly comes only from the artists' practice of Guru Yogs. The artist was not directed to paint Kelsang Gyatso Rinpoche on a lotus, nor was it her intention to do so in order to help 'create a myth' that Kelsang Gyatso Rinpoche is Guru Sumati Buddha Heruka and the only living holder of the Ganden Oral Lineage. For his disciples, of course he is regarded as an emanation of Guru Sumati Buddha Heruka, of course! The importance of having such a view is supported by extensive scriptural references. Whether or not he is the 'only' holder of said lineage is irrelevant nonsense, but he is definitely a holder of it, and having been requested to share it, he wrote the book so people could benefit.
The only reason they're trying to discredit Kelsang Gyatso Rinpoche is that he has criticized the Dalai Lama's sectarian abuse of people's rights. It is truly unfortunate for the world that the Dalai Lama has instituted the ban ("cultural revolution" in his own words), and unfortunate that his actions have solicited such extensive criticism and discrediting information about him. If he just respected everyone like the Buddha taught, there would have been harmony and no need to confront him or bring the 3 Jewels into disrepute.
Since the Dalai Lama is so insistent that he is carrying on the legacy of the 5th Dalai Lama, he should, as the 5th did, admit he was wrong about the Dharmapala, lift the ban, tell people to stop harming others, write a new praise to Dorje Shugden, built a temple for Dorje Shugden, and personally make a statue of this Protector.
