Some thirty or more years ago I took up hand reading as a hobby that soon grew into a vocation. I taught it for about ten years, spoke on it around the country in Western Canada and attended or hosted conferences on it in Europe, China, Taiwan, and Southeast Asia, becoming acquainted with some of the leaders in the field. I still administer one of the more active sites on Facebook, The Encyclopedia of Palmistry, named after my first book, and participated in several others. I have written a second book, Fingerprints and Behavior. I started as a complete skeptic, but most of my skepticism over possibilities has erased over time, though remain for some traditional nonsense.
For some time I have been interested in the effects of gem stones and rings on the behavior and thinking of the wearer. If you observe the hands of many Indian and other Asian businessmen, they are often seen wearing a gold ring with a yellow sapphire gemstone on the right index finger. Traditionally this is to boost self confidence and give them more power in business. Rather than write these traditions off, I like to explore if they work, and if they do, by what mechanism do they work, or what actions in the body do they represent.
Example: At one point I determined that the vertical crease in the middle of the palm going up to the middle finger represents the central axis of the body, at least well enough to predict potential break down points under gravity stress. This helped me understand why a mark was related to drowning in the older books. They said that if a star, a point where five or more lines meet or the more traditional shapes, is found just below the middle finger, the person will die by drowning. By following my logic, this could mean that the subject may have problems with balance, a very important capability in the days when travel included much crossing by and on water. Lose balance and you may drown.
Rings are commonly worn on the third phalange, though they can be worn on the middle or distal (nail) phalange. Checking Korean hand acupuncture, it is noted that not only does the finger have the two major meridians going through all these areas, but in the third phalange, there are additional branches of four other major meridians. Thus this is one of the most susceptible parts of the body to receive low-level energy that could be conducive to affecting the behavior and traits of the subject. When I suggested that this might be used for constant medication in the medical fields, one wag said that would be unlikely as you could not get a prescription refill every month and thus the pharmaceutical industry would not be impressed.
However, today I ran across an article on successful, though temporary, treatment of autism through the use of cannabis, either by the parent or child. The conclusions stated though the relief was temporary there was hope in the process: click here
It would be reasonable to begin studies on the applications of various energy-changing gem stones and metal rings that can be worn to effect a more permanent relief from autistic conditions and at a greatly reduced cost over the long run. These reliefs may actually be tailor-made for particular individual uses. Or we can just wait and let the Asians including the Indians do it.
