Thanks, Sajani. I really learned a lot from your essay, and am going to save it for future reference. I appreciate your taking the time to write it. I don't mean to clutter Jason's blog with more TM comments (sorry Jason), but I do have a couple minor points to share. From what I understand (and certainly I'm not as knowledgeable as you), the research on breath suspension wasn't able to be replicated. I think it was Kesterson's PhD dissertation. Also, Fred Travis, whose TM research you cite, has been collaborating with other top meditation researchers ever since his presentation at the New York Academy of Sciences (in 2013?) and their goal is to show the differences among meditation practices. He tries to avoid claiming one meditation is better than another, but rather has adopted the attitude that each has its unique effects.
