In the current issue (May 2015) of Mindfulness Magazine, the editor makes a good case of why the current fashion of mindfulness training is not "McMindfulness" at all. And as someone who teaches mindfulness as an areligious practical discipline, I obviously agree. And again, even though I understand how Yoga transitioned from a deep holistic spiritual practice to a way for Yuppies to get firm butts and tight abs, I see there are tons of benefits--individually and socially--derived from the practice of popular yoga. Further, as a practitioner of Chen Style Taijiquan who believes that the martial aspect of the art is synonymous with the healing aspect of the art, I have benefited enormously from Tai Chi as a health practice. Even further still, I fully support Paul Read's contention that we need to rescue Tai Chi from the past and redefine it for the 21st Century.
In short, we can be traditional practitioners of any given art and still teach, support, and/or endorse postmodern approaches. In fact, I believe these arts may cease to exist altogether if we try to restrain them to romantic concepts that are not in keeping with current reality. To be clear, I'm not saying that we shouldn't practice Taijiquan as a martial art, or Mindfulness and Yoga as serious enlightenment disciplines. But I'm also not saying we should. My advice to readers is my advice to my students: Find your path and follow it the way you feel led..but always leave yourself open to change and growth. In the meantime, live and let live.
