Barbara O’Brien a Zen practitioner has recently published an article about the Dorje Shugden Controversy Destroying Tibetan Buddhism in Order to Save It? Although the article does not investigate the events in India, a task which is difficult to undertake, the article is worthwhile reading it. It offers a short summery of the conflict for those who just want to get an idea of what the conflict is all about.
Investigative Journalist Raimondo Bultrini‘s article A Spirit of the XVII Century offers more details about the setting and some Tibetan lamas involved. The extensive former Wikipedia article Dorje Shugden, mainly based on academic researches, can be used to get a complete picture, including a review on the last media campaign.
