This statement implies that , in the first place, Dorje Shugden practitioners are dangerous.
“Dangerous” means causing harm to others or influencing others negatively , for example, to turn them away from their faith in the Three Jewels and to worship spirits instead, or breaking one's samaya or influencing others to break their samaya with their Guru. In these 3 respects, how have Dorje Shugden practitioners shown themselves to be dangerous ?
There is no solid irrevocable evidence that any Dorje Shugden practitioner has inflicted harm on someone. Dorje Shugden is an enlightened Protector , as all the great Shugden Masters testify to, and doing his practice has proven beneficial to all .As to going against the Dalai Lama, it revolves around the fact that one's samaya with one's root Guru is the most important thing of all. Breaking that samaya is as harmful to oneself as breaking one's refuge vows. We have to guard our vows as well as we guard our eyes. Going along with the Dalai Lama and following his instructions is most important if he were our root guru.I will always practice Shugden, as it was given to me by my root Guru and I will always rely on him as my Protector because he has never failed to come to my aid whenever I call on him.
