The following will highlight some fundamental techniques required for nei gong. Nei gong is also known as internal gongfu. Internal gong focuses on regulating the body, breathing, mind, qi, and spirit. It is impossible to cover all of this training here, so if you are interested, please refer to the books The Root of Chinese Qigong, The Essence of Taiji Qigong, and Qigong Meditation–Embryonic Breathing, by Dr. Yang, Jwing-Ming, published by YMAA Publication Center.
First, we will focus on exercises for regulating the breathing that allows you to build up the quantity of qi to an abundant level and subsequently circulate the accumulated qi. Practice these exercises in the order that they are presented. Become comfortable and proficient in one technique before moving on to the next.
