"Stephen Snyder and Tina Rasmussen know of what they write. They know through their own direct experience as dedicated yogis. Their book serves as a bridge for Westerners, a conduit to the traditional teachings of the Buddha as outlined in the discourses (sutras) and the Path of Purification (Visuddhimagga), as well as my book Knowing and Seeing. Many years ago, my teacher told me to plant the seed of this teaching in the West. Their book serves to water this seed and help it flower. I strongly recommend this book to all who are drawn to the meditative-absorptions (jhānas), and who seek to practice the Buddhist path as the Buddha lived and taught it" --Ven. Pa Auk Sayadaw (Abbot, Pa Auk Monastery, Burma).
"Written with great sincerity, precision, and grace, this is a unique road map to the extraordinary and transforming states of mind known as the jhānas. By two accomplished Western professionals, and drawing on the teachings of Pa Auk Sayadaw (widely regarded as a master of the jhānas), this book is both a fascinating account of the possible upper reaches of human potential and a step-by-step practice guide for how to get there. As a psychologist and as a practicing Buddhist, I recommend this book wholeheartedly" - Rick Hanson, Ph.D. (clinical psychologist).
