This video very clearly shows us that there is a ban. No matter how you argue over the use of the word 'ban', a ban is still a ban. It is a ban by virtual fact of the effects of its enforcement.
First, as a result of the ban, there is discrimination. Shugden worshippers are not allowed into shops, hospitals and clinics, and even schools run by Tibetans in the Tibetan community -in-exile. Shugden followers are blatantly ostracized, separated from families, and even deprived of jobs.
Those who are vocal and protest are put on the "hit" or "wanted" list, and they and their families live in fear for their lives and safety.
The Dalai Lama said that he had to come down hard on Shugden practitioners because they "had pushed themselves too far". I wonder how, Shugden practitioners had done this.
The sad part is that, just overnight, a 400 year old lineage practice (practiced by many great and realized Masters and even practiced by the 14th Dalai Lama himself for 40 years)is banned because the Dalai Lama said he had "made a mistake" in practicing it earlier. How can Avalokiteshvara ever make a mistake about a practice which has brought countless benefits to so many over hundreds of years. Furthermore, how could he have given up a practice given to him by His own guru?
