In the arresting movie, Children of Men, there was a brilliant characterization of yoga/healing culture. Several times, the midwife character who's helping Theo and Ki, invokes Shanti and chants Om Mani Padme Om. She even gets skeptical Ki to chant when when they are burying the leader of the Fishes, Julienne.
The midwife character is a bridge--she is key to the escape and she gives her life for the child about to be born. But she doesn't get to see Ki delivered into the right hands. That's left to morally exhausted Theo.
The midwife is struggling to live in an unlivable world, do what's right, and have hope. You get a sense that she has to deceive herself to do this. Chanting Om Mani Padme Om gently underscores this: Julienne has been shot in the neck, murdered by her own people. She's buried in an unmarked grave in the woods, in desperate circumstances. There is no redemption. If there is a soul, if there is a god, if there is a healing power, or a guiding light, we don't see it in this movie. The midwife character invokes Shanti in spite of the overwhelming evidence that Shanti is meaningless here.
Sometimes this is how the "healing" around yoga culture seems: harmless when times are good. But how effective would it be if the government and the terrorists were trying to kill you?
