Advance Acclaim for Essential Spirituality By Roger Walsh, M.D., PH.D. "Deceptively simple. Its power is rooted not only in Dr. Walsh’s formidable intellectual capacity to effectively deal with a vast body of religious literature but in his own deep spiritual practices in a multitude of disciplines over many years. An important contribution." —Ram Dass, author of Be Here Now "An absolute masterpiece … Essential Spirituality is helpful to both the unseasoned and seasoned seeker. The writing is deep, simple, and clear yet at the same time poetic and musical. A must read." —Gerald G. Jampolsky, M.D., author of Love Is Letting Go of Fear "Energetic, engaged, and occasionally electrifying…Roger is thoroughly grounded in actual spiritual practices, without which any writing on spiritual topics remains anemic and untrustworthy." —Ken Wilber, author of One Taste and A Brief History of Everything "Groundbreaking…Essential Spirituality is the first book that identifies and brings together the shared practices found in the world’s religions." —Angeles Arrien, Ph.D., author of The Four-Fold Way "I could not imagine a better person to write this book." —Charles Taft, Ph.D., author of Waking Up "A truly groundbreaking and seminal work…an invaluable guidebook for modern spiritual seekers." —Stanislav Grof, M.D., author of Beyond the Brain and The Cosmic Game "Essential Spirituality is as significant as Aldous Huxley’s The Perennial Philosophy and could be one of the most important books of our times. It deals with profound spiritual issues in a very clear and down-to-earth way and provides practical exercises that are simple, straightforward, and effective." —Peter Russell, author of The Global Brain Awakens "A wonderful and practical overview for anyone wanting to begin a spiritual journey." —Philip Moffitt, former editor of Esquire magazine
