A prisoner recommended yesterday this film by Vikram Gandhi to me. The movie highlights the naive devotion of Westerners to Asian gurus as well as the issue of that even blind faith in wrong gurus can lead to good experiences due to the pure nature of sentient beings mind and the power of faith. I think the movie has a lot to teach.

Another good film about fake gurus is this one about Osho / Bhagwan: http://www.gurufilm.ch/
