Qigong (also spelled Ch’i Kung and pronounced chee gung) is a powerful system of healing and energy medicine from China. It is the art and science of using breathing techniques, gentle movement, and meditation to cleanse, strengthen, and circulate the life energy (qi). Qigong practice leads to better health and vitality and a tranquil state of mind. In the past, qigong was also called nei gong (inner work) and dao yin (guiding energy).
