The wrathful protectors are the single most misread part of Tibetan Buddhism. They are not demons and not evil gods: most are the ferocious aspect of a compassionate figure, deliberately terrifying because the obstacles they address — pride, laziness, self-deception — are not touched by gentleness. Many began as indigenous Tibetan or Mongolian deities and were bound into service rather than driven out, which is why their worship carries a distinctly pre-Buddhist flavour. The line between a protector practice and ordinary propitiation is genuinely thin, and the twentieth-century controversy over the protector Dorje Shugden — which split communities and ended in violence — shows how thin.
