Treat Damaged Organs with the Power of Sounds

A gorilla doesn’t rap on his chest for nothing. In Chinese medicine the thymus gland, situated at the bottom of the neck and running towards the sternum in a tuber shape, is most important in the control of the flow of ch’i.
Certain sounds are said to have an effect upon certain organs, and if we use these sounds in conjunction with the tapping then we are able to heal the controller of ch’i.
Close your fists and rap on your chest lightly twice as you breathe in. Now as you throw both fists back as far as they will go in an explosive manner, say the sound ‘HA. Be sure to have a light practice before to warm up the muscles, because the chest and back are stretched.
The sound ‘HA strengthens the heart but the sound must come from the lower belly and really try to knock out the back wall with the sound. Try not to be around other people as they will think you quite mad.
Practise the same arm movements with all the other sounds, and make the sounds come from the lower belly:
The sound ‘TSSSS’ strengthens the lungs.
The sound ‘SHU’ strengthens the liver.
The sound ‘FU strengthens the kidneys.
The sound ‘HU’ strengthens the spleen.
The sound ‘SHI’ strengthens the solar plexus.
Take this exercise easy at first and stretch the muscles before you start. If you are treating a particular organ that is damaged, repeat the sound 36 times. For general good health repeat only 5 times.
