Another essential text for all yoga enthusiasts. Sarah Powers, Co-founder of the Insight Yoga Institute and Author of Insight Yoga and Lit from WithinHaving read all of Bernie’s books, this is by far my favorite. It’s a wonderful mix of the personal, scientific, and creative that explores not only the earliest origins and history of yoga but its underlying energetic and mystical aspects as well. Many of us as teachers have pondered these deep questions, and Bernie has brought his unique perspective to fleshing them out in ways that illuminate the principles and teachings that make yoga universal.J. Brown, Host of the Yoga Talks podcastPrana is a key concept in yoga theory and practice. But what is prana? Is prana a god? A physical force? Or the power that connects the immaterial soul to the material body? Is it just an ancient name for bio-electricity, or is it an intelligent life-force that modern science is slowly uncovering? Bernie Clark’s new book, Prana, explores these questions by tracing the historical uses of the word prana in ancient and modern cultures. He has created masterfully imagined dialogues between ancient yogis, Greek philosophers, Taoist sages, and modern theosophists. His book is interwoven with Bernie’s own experiences and culminates with a review of modern scientific investigations and theories. It is well researched, clearly written, and full of references. Read Bernie’s book Prana. It might make you reconsider what prana is, and how breathing exercises and physical asanas influence it manifestations.Paul Grilley, Author of Yin Yoga: Principles and Practice and Chakra Theory and MeditationAs a science educator, I’ve long struggled to reconcile the esoteric ideas of “prana” and “chakras” with scientific thinking. In Prana, Bernie Clark doesn’t resolve that tension—he honors it. Blending myth, history, and modern insight, he invites us not into certainty but into informed wonder. Whether you’re a skeptic or a seeker, Prana offers a compelling and nuanced map for exploring one of yoga’s most elusive concepts, making it a must-read for any yogi.Matthew Huy, Co-author of The Physiology of Yoga and Co-founder of the Enlightened Yoga Collective
