The sound exercise of the Taijiwuxigong system is used much like a mantra, however, without a religious context. Dr. Shen. Hongxun discovered a particular sound by accident. As a young man, he followed lessons with Master Yao Huanzi who gave his students a mantra for homework. Dr. Shen had not understood the exercise correctly and practiced pronouncing the word ‘mantra’ instead. By repeating this sound, he discovered that it activated his energy centres and channels.
Afterwards, Dr. Shen learned the principles of sound vibration from his teacher Fahai Lama. Using these principles he developed his mantra and investigated the positive reactions when used for specific complaints, such as insomnia.
