Sorry but I guess I am furthering this tangent. Mindfulness is increasingly being used in clinical psychology. I had a lecture about mindfulness and thought it was a lot of rubbish at the time. But as part of my psychiatry rotation, I have attended a couple of mindfulness sessions and actually seen some significant breakthroughs in patients with depression and anxiety from just one session.
I didn't know about the Buddhist link until reading your post. There was nothing at all Buddhist about the sessions I went to unless you think closing your eyes and concentrating on your sensations, feelings and thoughts to be exclusively Buddhist activities. Practicing mindfulness will not turn people into Buddhists any more than going to Alcoholics Anonymous meetings (which was a Christian creation) will turn you into a Christian.
Yes, this is Buddhist, and I have been aware for some time about it's use in psychology. The concentration on sensations, feelings, and thoughts the way they teach it is for the person to be non-judgmental and to disengage from judging and thinking. This is part of the process of non-attachment in Buddhism. Since Buddhism believes that desire causes suffering (and desire includes thinking with any attachments or judgment), the way out is to cultivate non-attachment through techniques, which include various meditations and mindfulness.
Buddhism in the West is very adept at not using Buddhist or spiritual terms. People like the Dalai Lama and others have successfully marketed it as a psychological aid and process. It is, however, spiritual.
I am very, very familiar with this and have given lectures on Buddhism, particularly Buddhist meditation and mindfulness. It does affect the mind and it is spiritual in nature. I practiced Buddhist meditation for about 14 years and know it from the inside out.
I recently answered an email from a psychology student in the UK who attended a seminar on mindfulness and came across my website and asked me about this. Also, I am going to be on a radio show on Dec. 12 on the topic of Buddhist meditation. Check my website's schedule (just click on my name to get to it) to see the link to hear it live.
