To my parents, who guided me lovingly, watched my life with joy and enthusiasm, supported my academic and personal interests, and always thought the best of me.
Why do you never find anything written about that idiosyncratic thought you advert to, about your fascination with something no one else understands? Because it is up to you. There is something you find interesting, for a reason hard to explain. It is hard to explain because you have never read it on any page; there you begin. You were made and set here to give voice to this, your own astonishment.
Annie Dillard, in The Writing Life

FOREWORD
H atha yoga. Its teachers and serious students are convinced of its power to build strength and confidence, to improve flexibility and balance, and to foster spiritual peace and contentment. And beyond its attributes as preventive medicine, many of us also believe in the power of yoga to heal, to aid in recovering from everything from low back strain to carpal tunnel syndrome and to help cope with chronic problems like arthritis, multiple sclerosis and infection with the human immunodeficiency virus (HIV).
But despite the recent boom in yogas popularity, most scientists and physicians have been slow to embrace this discipline. To many of them perhaps, it seems like a mystical pursuit, a quasi-religion with little basis in the modern world of science. In a medical profession now itself dominated by a near religious reverence for the randomized, controlled study, knowledge acquired through thousands of years of direct observation, introspection, and trial and error may seem quaint.
But as the West has slowly opened in the past decades to Eastern, experientially based fields like acupunctureas part of a greater acceptance of alternative medicine in generalyoga has begun to stake its claim. Concepts like prana or chi, however, are not warmly received by skeptical scientists. To win them over you need to provide the kind of evidence they buy. Studies. Preferably published in peer-review journals. And you need to propose mechanisms of action that conform with science as they understand it.
A significant breakthrough was provided by Dr. Dean Ornish, a California-based cardiologist who interrupted his college years to study with Sri Swami Satchidananda. His work, published in 1990 in the prestigious British medical journal the Lancet, showed that a program that combines hatha yoga with dietary changes, exercise, and group therapy can actually reverse blockages in the hearts main arterieswhich doctors used to think wasnt possible.
In 1998, research led by Marian Garfinkel of the Medical College of Pennsylvania and published in the Journal of the American Medical Association found that Iyengar yoga could effectively reduce the symptoms of carpal tunnel syndrome, a malady of near epidemic proportions in this computer age. Of note, Garfinkels study lasted only eight weeks, and yet the intervention proved efficacious. Serious yoga practitioners realize of course that although some benefit may be noticed after even a single class, yogas most profound effects accrue over yearseven decadesnot weeks. Yoga is indeed powerful medicine but it is slow medicine.
More studies will be needed to convince the medical establishment, but that research could also be slow in coming. Funding is a perennial problem. Unlike the situation with, say, pharmaceuticals, there is no private industry to bankroll the scientific investigation of hatha yoga. Given the incredible cost of long-range studieswhich are more likely to demonstrate effectivenessI suspect that were unlikely to see any time soon the kind of overwhelming proof that skeptical scientists want. This presents a philosophical question:When you have an intervention which appears safe and effectiveand when its side effects are almost entirely positiveshould one wait for proof before trying it? This value judgment lies at the heart of the recent debate over many traditional healing methods.
Ironically, though, even within the world of alternative medicine yoga seems under-appreciated. Two years ago, I attended a four-day conference on alternative medicine sponsored by Harvard Medical School. A wide range of topics from herbs to prayer to homeopathy were covered in detail. Yet in the dozens of presentations I attended, yoga was mentioned just once: In a slide that accompanied the lecture on cardiovascular disease, yoga was one of several modalities listed under Other Stress Reduction Techniques. Yoga is certainly a stress reduction device but to reduce it to just that misses so much.
