I assume that response was to me? I dont' know enough about the presentation John was referring to. He just said "26-year zen practitioner" and of course, this reference to a zen practitioner was presented at a conference that ended a couple of weeks ago, so I don't know any more details.
As far as the Ch'an paper goes, this paper http://ftp.cs.kun.nl/CompMath.Found/Meditation_V01.pdf http://ftp.cs.kun.nl/CompMath.Found/Meditation_V01.pdf Shows that people who practice VIpassana or Ch'an Mo'chao show a Type B microstate preponderance, while I am expecting that TMers to show a Type C microstate preponderance outside of TM and a Type D microstate (or some more global activation state beyond it) during TM practice. On the other hand, THIS paper DOES report Type C microstates showing up more in Zen practitioners: http://ieeexplore.ieee.org/xpl/articleDetails.jsp?tp=&arnumber=5212377&url=http%3A%2F%2Fieeexplore.ieee.org%2Fxpls%2Fabs_all.jsp%3Farnumber%3D5212377 http://ieeexplore.ieee.org/xpl/articleDetails.jsp?tp=&arnumber=5212377&url=http%3A%2F%2Fieeexplore.ieee.org%2Fxpls%2Fabs_all.jsp%3Farnumber%3D5212377 Until we can do head-to-head studies, it will be hard to make direct comparisons, of course.

That is the usual TMO mode of generalization, based as it is upon proselytizing, but in this forum we are not the usual wide-eyed suchophants. We would think that you could do better but as a proselyte - maybe not.
