As an American clinical psychologist living in a community (Asheville, North Carolina) where both NVC and RC are very popular, I'm glad to see these being used in Auroville.
Having said that, I feel deeply saddened that techniques aimed at what Sri Aurobindo characterized as the superficial, surface consciousness are not being adapted along the lines of the deeper integral yoga vision.
Jan (my wife) and I hope to be able to visit Auroville more regularly beginning some time in the next year or two. I've been hearing for many years that people in Auroville don't really spent time actually studying the writings of Mother and Sri Aurobindo. I am not so much of a cultist as to say, "You don't need NVC or RC - just read Mother and Sri Aurobindo".
But it is rather strange and perplexing that the Aurovillian approach seems so much the opposite - practice mindfulness, try out NVC, RC or whatever, and even if we borrow a bit from Integral Yoga (Awareness Through the Body) only take as much as can be made to accommodate to the surface, modern consciousness, with perhaps a mention or two of the psychic being thrown in.
I hope this changes substantially in the coming years, as I believe the lack of in-depth, deep attention to Integral Yoga is at the root of all the problems Auroville faces.
