Book excerpt: "Over millennia, many Eastern traditions have developed practices that use the powerful healing energy of breath to treat physical, emotional, and mental problems. In Chinese, this energy is called chi; in Indian Sanskrit it is called prana, and in Tibetan it is called lung. Lung is life-giving energy that moves through our bodies. A lack or imbalance of lung can create illnesses of body and mind or cause emotional struggles such as confusion, anger, and depression. In this book, Geshe YongDong Losar, a scholar and monk in the ancient Bön tradition of Tibet, guides us through powerful practices to help balance our lung. His deep knowledge-garnered through years of study and practice-renders the practices simple and achievable, creating a clear path for us toward greater calmness, strength, and clarity. Over and over I have personally witnessed, both in myself and in my students, the breath's clear potential to heal and deeply transform lives. I truly believe that in the future such practices will play an important role as a medicine for preventing and treating physical, emotional, and mental maladies. I am glad that Geshe YongDong is making these practices widely available, and I'm sure that by doing so, he is bringing benefit to countless lives"--
