This outstanding documentary on the oracles of Tibet deserves comparison with Maya Deren’s classic Divine Horsemen: The Living Gods of Haiti.
The film is served by YouTube’s UFO channel, which presents in a pretty far-out style, but don’t let that throw you. It stays on solid ground, reporting accurately and matter-of-factly about Tibetan beliefs.
Thanks to Erik Davis of Techgnosis for the tip.
Also recommended (for the seriously interested) is Rene de Nebesky-Wojkowitz’s classic Oracles and Demons of Tibet, available from the excellent Fields Online Book Store.
