The author genuinely tries to evaluate Transcendental Meditation and the Maharishi Mahesh Yogi objectively, and seems to succeed. The book is evaluative, shows pros and cons, and leaves the decision up to the reader. It is well–researched. White seems to have depth and breadth of knowledge. There is a good description of how to do TM. He even reveals his own mantra, which TM forbids that he do. He also explains the basis on which mantras are assigned, also forbidden by TM. However, White is vague about his own educational background. He has degrees from Dartmouth and Yale, but doesn't say what in or how advanced. He also at times allows his own prejudices in, although they don't directly involve TM. My biggest problem with the book is that the science (and there's a lot of it) is way out of date, since the book was published in 1976.
