I have no feeling about meditation one way or another, but "imaging studies showing changes to the brain" does not seem relevant to anything, unless said changes to the brain have a compelling causal link to something. Having people do something and watching their brains light up is cool, but without taking it much further is hardly evidence of the efficacy of meditation one way or the other. After all, changes in my skin conductivity do not suggest that I'm being haunted by thetans.
