What's awesome about The Merlin Gate is that all the stuff about Yi, Qi, Qigong and Tai Chi is real! In some of the chapters you'll even find secrets to internal training that have rarely been taught in the West.
The author, M. W. Caudron, has studied with Chinese Masters and even a Grand Master, and has practiced Tai Chi and Qigong for almost 30 years. She lives in Colorado, where she teaches Tai Chi and heals people with Medical Qigong.
M. W. Caudron also taught Eastern religions for a number of years. So you can bet that all the cool info that Dr. Crane teaches at Merlin High in World Religions class is accurate.
