The previous Dudjom Rinpoche (pictured below) was well known to indiscriminately speak against Dorje Shugden. He seemed to be quite a sectarian anti-Gelug person. He had no right to criticize any Gelug protectors or the Gelug Lineage in any way. He was even arrested in North India and thrown into jail for a short while, till the Tibetan Govt in the 70's intervened and got him out.
He built a small Monastery in Kathmandu that was infamous for having a Dorje Drolod statue stepping on Shugden and tearing Shugden's heart out. Previous 17th Karmapa was very displeased with this representation according to Kyabje Dagom Rinpoche's writings. In Tibet there is no such representation with Dorje Drolod stepping on Shugden. It was a new creation by Dudjom Rinpoche while he was in Nepal. He created alot of negative sentiments with his anit-Shugden rhetorics. This was way before the ban. This was already happening in the late 80's.
Dudjom Rinpoche also came up with Anti-Shugden chakras (pictured below). You take these chakras, fold and tied with multi colored string. Then pujas done according to Dudjom Rinpoche. Afterwards, the person wearing this chakra is protected from all 'harm' and 'ill influence' of Dorje Shugden. It was a small rage in Kathmandu for a short while and then died down. I mean, think about it, there are millions of negative powerful spirits, but there is a special chakra just to counter Shugden? I mean they really are fearful of Shugden. Shugden sure is a super powerful being.
I find it quite amusing and at the same time interesting that a so called high ranking personage such as Dudjom Rinpoche would bring himself to create such chakras and protect people against Shugden. If Shugden was or is a evil spirit, I don't think a chakra would protect anyone. How can a folded piece of paper be more powerful than fire pujas and other rites? Fire pujas and rituals have been done against Shugden many times. How come so many high ranking lamas cannot eliminate Shugden? Is Shugden more powerful than all of them? If he is, that does not say much for these Lamas. Think about it, if Shugden is powerful enough to harm the Dalai Lama (of course Shugden harms nobody), how can a piece a paper with scorpions protect you ? Doesn't make sense in any way. Unless Shugden is not an evil spirit, but an attained being therefore invincible.
The chakras are very interesting nevertheless.
