DORE SHUGDEN
Defender of Purity
Protector of the Gelug sect of Tibetan Buddhism, Dore Shugden returns to purify and restore the values corrupted by the child trafficking necromancer the accursed Dalia Lama
In the 1930s, Pabongkhapa Déchen Nyingpo, who favored an "exclusive" stance, started to promote Shugden as a major protector of the Gelug school, who harms any Gelug practitioner who blends his practice with non-Gelug practices.
The conflict reappeared with the publication of the Yellow Book in 1976, containing stories about wrathful acts of Dorje Shugden against Gelugpas who also practiced Nyingma teachings. In response, the 14th Dalai Lama, a Gelugpa himself and advocate of an "inclusive" approach to the teachings of Tibetan Buddhism, started to speak out against the practice of Dorje Shugden in 1978
