Chi Nei Tsang, a form of abdominal massage from traditional Chinese medicine, was popularized in the Western world by Mantak Chia. A master of Qi Gong and other Eastern health disciplines, Mantak Chia incorporated Chi Nei Tsang into a holistic wellness system that includes meditation, breathing techniques, and Qi Gong. This approach is based on the understanding that the abdomen is a vital center for emotional and energetic processing, where unresolved emotions and stress can create blockages that disrupt the flow of energy, or Qi.
