There are a number of good exercises (posture & breathing--though holding the breath for healing etc. is discounted) & wise observations (the value of balance & mindfulness meditation) in this book, but mostly it depicts the author's personal, impressionistic path. It includes Tilopa's famous & wonderful Mahamudra (MM) Song as an appendix, however, the book is not a commentary on it. The author uses only 3 lines of it to expound his personal views--heavily oriented towards the physical: bodywork, Hatha Yoga, dance, & the author's inventive "somatic koans." There's a Hindu bent to the book: the cover is a picture of the Hindu god Shiva, & the author advocates p. 144 "walk in Shiva's path." He repeatedly uses theistic terminology & Western mystical concepts--fine for comparison purposes, but not MM. Despite his rhetoric, Hinduism has nothing to do with MM, a Tibetan Buddhist wisdom teaching--the highest one of the Kagyu school (there's also a Gelugpa version--see the Dalai Lama's book). The author describes some Theravada Buddhist practices, but MM is a Vajrayana practice--a type of Mahayana, not Theravada--they don't practice MM. He also mentions Rinzai--a Japanese Mahayana but not Vajrayana sect (as is Japanese Shingon). While I agree with him that p. 144 "The practice is always one of personal exploration & personal discovery," his title is misleading; his teachings are not authentic MM. At best it's a low level, very loose, physically-oriented, New Age interpretation of a very high level, authentic, numinous, noetic path. In Hindu terms, it's a Hatha Yoga interpretation of Jnana Yoga. In Jungian/Myers-Briggs terms, it seems to be Extroverted, Sensate, Feeler, Perceptive. Since I'm far from that, (iNtuitive Thinker), I don't attune well with it--indeed, if I'd read this review before buying the book, I wouldn't have. Still, it's valuable to develop one's inferior function (Sensate for me), it's strong suit is my weak suit, & beauty is in the eye of the beholder--others may love it. It is easy to read.
But, it doesn't compare with other books I've read:
-- Osho's "Tantra-the Supreme Understanding," an enlightening/impressive interpretation of Tilopa's Song
-- Eckhart Tolle's "The Power of Now," a fine, new age oriented view of mindfulness
-- Traleg Kyabgon's "Mind at Ease," a terrific easy-to-read explanation of MM
-- Khenchen Thrangu Rinpoche & Alexander Berzin's several translations/commentaries on volumes of the 9th Karmapa's wonderful MM trilogy
-- Takpo Tashi Namgyal's amazing "Mahamudra: The Quintessence of Mind and Meditation" (an English version of "Moonbeams of MM"), the "bible" of MM, if there is one
In addition to Tilopa's Song, Johnson quotes (p. 143) Niguma's wonderful MM stanza (with more MM than his book!)--Don't do anything whatsoever with the mind, Just abide in an authentic, natural state.
One's own mind, unwavering, is reality. The key is to meditate like this without wavering.
