William Broad, a science journalist, senior writer at the New York Times, and a lifelong practitioner of yoga, presents a pioneering, engaging, and impartial evaluation of yoga; a discipline that began thousands of years ago and improbably evolved into one of today’s most popular fitness activities. Uncommon states are integral to a hidden world of risk and reward that lies beneath clouds of myth, superstition, and hype. The Science of Yoga celebrates what’s real and shows what’s illusory, describes what’s uplifting and beneficial, and what’s flaky and dangerous — and why. Broad illuminates how yoga can lift moods and inspire creativity. He also exposes moves that can cripple and kill. As science often does, this groundbreaking book also reveals mysteries. It presents a fascinating body of evidence that raises questions about whether humans have latent capabilities for entering states of suspended animation and unremitting sexual bliss. Broad also unveils a burgeoning global industry that attracts not only curious scientists but true believers and charismatic hustlers. In the end, he shatters myths, lays out unexpected benefits, and offers a compelling vision of how the ancient practice can be improved.
