The sounds of the Five Hun Yuan Form (level three) are spoken by Dr. Pang.
They are used for practitioners to learn to say these sounds correctly. You can listen to each sound and at same time say it and experience inner change of qi vibration. Not so long, you will practice the sounds well. You can practice only one sound at each time, you also can practice all the sounds one by one in each time follow the sequence of hunyuan qiao, heart, kidney, pancreas, liver, lung.
The heart sounds in Chinese are: xing – xin – xiang
Saying “xing, xin, xiang” is for practicing the heart qi for healing heart problems and making the heart stronger; you can practice it singly.
