The exercises of the Healing Sounds (Liuzijue 六字诀) are very old, and go back to a famous Daoist master and pharmacologist of the 6th century, Tao Hongjing 陶弘景.
This is the Healing Sound exercise for the Liver, which is the organ responsible for the free and easy flow of energy through your body.
The sound associated with this exercise is "SHUU", which we only think in our imagination while we're exhaling the breath through the mouth.
This exercise is part of the same set as the previous exercises for the Lung and San Jiao.
They can be practised together in this order: Lung, liver, San Jiao.
