Query: Opening the Dragon Gate

This is a wonderful book that I would definitely recommend to anyone interested in Taoism and esoteric taoist practices. This book is a must have for people currently practicing or interested in practicing meditation and mind cultivation as it explains in depth the secrets of the mind. Martial Artists should definitely purchase this book due to the in depth explanation of the internal systems which compliment and enrich the external styles.
