pioneer of seasonal affective disorder research describes with enthusiasm his practice, begun just a few years ago, of Transcendental Meditation. Reviews research on its effects on blood pressure, anxiety, etc. and provides supplementary favorable anecdotes from his own perspective as well as from interviews with famous (Paul McCartney, Martin Scorsese, David Lynch,......) and not-famous practitioners.
He goes over the details of some studies (including mine...thanks for the citations, Dr. Rosenthal!), and there is extensive information on the nature and history of the practice, but it is not really objective or critical analysis. A simple example -- there are many many positive anecdotes, but he ignores the (easily googled) unfavorable anecdotes from people who believe they've been harmed by TM practice. There is a brief discussion of potential "side effects" but the most serious ones are said to be "rare in people without significant emotional problems". Since the rest of the book touts use of TM, sometimes based on admittedly preliminary pilot studies and the like, for vets with PTSD, bipolar disorder patients, etc., that is not necessarily a reassuring qualifier.
minor quibble -- for an experienced clinician, he doesn't seem to be adept at disguising case studies. One of the non-famous people cited a number of times is someone I know. He uses only the person's first name, which makes me think the intent was to be anonymous, but many unnecessary identifying details are included.
All told, a very good source if you want a description of TM and encouragement to learn and practice it. Needs supplementation if you want an objective perspective on its effects.
