For the past 20 years, the CTA has been saying Dorje Shugden is an evil spirit, whoever practices Dorje Shugden will take rebirth in hell. They also say Dorje Shugden is very harmful and we should stay away from him. The ban was imposed to stop people from practicing.
There are a few questions the CTA should answer us before they attack Dorje Shugden and Dorje Shugden followers. Tibetan Buddhism is famous for its rituals. There are many rituals a high master can do to subdue a spirit. How come until today there is no one who can subdue Dorje Shugden? If all the Buddhist masters, high lamas are very attained and powerful, why do they have to be afraid of Dorje Shugden? They will have the protection from the 3 Jewels, they don't have to be afraid of anything.
If Dorje Shugden is an evil spirit, why are so many Dorje Shugden lamas keep coming back in the human form? They should have been born in hell for taking refuge in an evil spirit. The funny thing is the CTA and the Dalai Lama recognised the reincarnations of these lamas. For example, Trijang Rinpoche, Zong Rinpoche, Lati Rinpoche, Lama Yeshe and many more. If what the CTA and the Dalai Lama say about Dorje Shugden is true, does it mean they have recognised the wrong tulkus?
