The theoretical basis of Six healing Qigong sounds (Liu Zi Jue) is the Five Elements of Traditional Chinese Medicine (metal, wood, water, fire and earth), and Five Solid Viscera (heart, liver, spleen, lungs and kidneys). The Six healing Qigong sounds gently vibrate, and massage our internal organs, boost our immune system, clear stagnation and stale energy from our body, harmonize our emotions, balance our body and spirit creating a state of inner peace and radiant energy. The sound Xu tonify Liver energy, Hoo replenish Spleen energy, Her nourish Heart energy, Si nourish Lung energy, Chui tonify the Kidney energy, and Xi revitalize San Jiao energy (the Traditional Chinese Medicine term for the hollow space inside the trunk of your body) that altogether cultivate the Three Treasures Jing, Qi and Shen and strengthen the Wei Qi field. The Qigong forms with six healing sounds are illustrated in the book for your healing and spiritual awakening. "If your Qi is in balance, your health and wellness are unlimited." – Master Faye Li Yip
