Here is a picture of a typical Chinese Face Mapping sketch. Their theory is that the skin we have on the outside reflects what we are experiencing on the inside.
“In Jin Shin Jyutsu, our hands work as jumper cables that enable us to recharge our body, mind and spirit and restore a harmonious flow of energy, which is key to health and balance.
See the photo above for benefits of performing the thumb hold. Hold your thumb until you can sense a pulsing in it; or, if you don’t feel your pulse easily, hold it for about three minutes.
Once you perform the technique a few times, you will quickly develop an intuitive understanding of how long you need to hold it in order to feel relief. In addition to your thumb, you can perform holds on other fingers.”
