Qigong can be described as a mind-body-spirit practice that improves one’s mental and physical health by integrating posture, movement, breathing technique, self-massage, sound, and focused intent. There are likely thousands of qigong styles, schools, traditions, forms, and lineages, each with practical applications and different theories about Qi (“subtle breath” or “vital energy”) and Gong (“skill cultivated through steady practice”). The mission of the National Qigong Association is to help each individual find a path that best supports their personal goals, and to evolve this amazing energetic science.
