Basic Research on Effectiveness of Mindfulness Skills
When an evidence-based approach becomes popularized and clinical training standard are lowered, we may experience reports on exaggerated success of the specific intervention. The same may occur when researchers have pro/con biases. This is especially true when the provider/trainer is not a regular practitioner of the same MBIs. Now that MBIs are common in public/private school, community clinics, professional sports, and governmental organization (the Veterans Administration, etc.), both standards of care and quality of instruction must be monitored to prevent generalization drift. Generalization drift occurs when more and more people with less clinical training and experience, teach and use the MBIs. Double-sided reflection on this process would suggest a mixed picture: more and more people are 
learning to use secular MBIs to improve their lives (a good thing), but quality of training and experience of people teaching MBIs may be less than adequate for both safety and success (not a good thing). Remember that there are potential negative effects on people using MBIs. In my own 20-year experience as a MBI trainer in school, clinics and medical services programs, I have witnessed this process over and over again. In particular, when trainers/teachers used “canned” instructional programs published for profit and NOT adequately evaluated for reliability and validity, the drift and exaggerated claim may increase. When I co-led a school-based MBIs program for five years in a well-respected public school system in Vermont, we made sure the outcome research was completed by an independent and competent evaluation organization. We did this to prevent researcher-bias. Since I and other trainers were sold on the effectiveness of MBIs, it was best to have the outcome research done by others. The reason why the program was re-funded year after year was due solely to its positive effectiveness. I am happy to report that the outcomes of that specific school-based MBIs intervention were very positive and long-lasting.
In my own reasonably complete review of research I have concluded that we are better off being conservative in our claims of effectiveness. Thus I am very comfortable noting that when MBIs are provided by well-trained and experienced trainers they DO Improve conditions related to depression, anxiety, chronic pan and to a lesser degree stress reactivity and emotion self-regulation. Emotion regulation is a very important finding; this one outcome is directly related to conditions involving unresolved psychological trauma and addictions. I need say no more about the common realities of both these conditions in our American culture; we self-medicate to keep the economy going and to combat negative mood states, we have high levels of adverse childhood experiences, and we have fear and shame in seeking help for traumatic experiences and addictions. The story of positive familial attachment experiences in our country is a very sad one; we have high 
numbers of children experiences ACEs or Adverse Childhood Experiences. As far as prosocial changes related to exposure to MBIs, the research picture is less supportive. There are claims that MBIs improve compassion, empathy, connectivity with others, aggression, and prejudice in various settings. However, research support suggests that there are some improvements in compassion and empathy, but very little real evidence for improving connectivity, aggression and prejudice. In positive effects on various conditions, long-term regular meditation (with breathing retraining) practice leads the way, followed closely by long-term regular yoga and body scanning practice. “Forest Bathing,” or long-term mindful walking in nature has research support for improving general health and psychological well-being. Other MBIs/practices like qigong, tai chi, etc. do improve specific conditions but we are hard-pressed to say that they are as powerful for most people as meditation, breath training, yoga, body scanning or Forest Bathing. That said, for some people qigong and tai chi make huge differences in the quality of their lives and sense of well-being. Vigorous forms of qigong and tai chi are like mindful exercise, and according to a solid body of research regular vigorous exercise is your best path to good psychological and physical health.

Possible Negative Emotional Effects of MBIs Practices:
Some people experience negative effects from MBIs. This is usually due to an underlying mental health or psychological condition and/or ineffective instruction from an inadequate, inexperienced trainer/teacher, etc. Some of the most severe negative effects occur after long-term, silent retreats – sometimes vipassana retreats. Negative effects may occur on the first major exposure to MBIs. or after repeated exposures where no negative effects existed.

authentic entities outside/inside the self. It is more likely that personal experience has conditioned the person to understand these variable processes as quite serious and sometimes dangerous. To maintain a clear boundary, this post is not presenting a way to treat people suffering from any form of identity disorder; rather, this post offer some ideas about how one might go about becoming healthier via less targeted clinical interventions. The remaining part of the post will offer comments and suggestions for personal consideration of the reader. Most content deals with realistic natural phenomena in life. I hope I am making myself clear here. I hope you find the content helpful.
tension leaving our mind and body. This alone may enable one to experience waves of deep relaxation and peace of mind. However, this first stage is simply preparation for other yoga nidra techniques. If practice time is extended, sometimes people experience a drop in body temperature.
meditations below are presented to expand the use of interoceptive processes in therapy practice. They are presented in very brief form, so slow down the work when using these in your therapy practice. Rather than repeating the introductory process, I will note it here. Be sure to use it in each meditation.
end suffering. It will not! Make space for them rather than treating them as your enemy. Befriending via wise mind skills and calm abiding may lead to reduced impact on your emotions. You may even make these conditions your allies, all trying to teach you something that will help you do better, be better. Use self-compassion often.
