The Shugden controversy revolves around the worship of Dorje Shugden, a deity in Tibetan Buddhism. Some followers believe that Shugden provides protection and blessings, while others, including prominent figures like the Dalai Lama, argue that the practice is harmful and promotes sectarianism within the Buddhist community. The disagreement has led to significant tensions among Tibetan Buddhists, with some groups supporting Shugden worship and others opposing it. This division has affected relationships between different sects, particularly between the Gelug school, which the Dalai Lama represents, and those who advocate for Shugden.
