The paper features diagrams of tefillin-laying and explanations of the various acupuncture points they stimulate.
The acknowledged purpose of the tefillin is to raise spiritual consciousness of the men who wear it. If we examine where the knots and wrappings are placed from a TCM point of view, it appears that the tefillin and wraps form a potent acupuncture point formula focused on the Governing vessel (Du Mai) and aimed at elevating the spirit and clearing the mind.
I explored the four major variations in wrapping procedures: Chassidic, Sefardim, Sefard, and Ashkenazi. By experimenting on myself with these different wrapping procedures, I was able to map out the significant acupuncture points that are stimulated through the procedure.
If someone handed an acupuncturist the above point formula and asked what was being treated, there is little doubt that mental and shen issues would be a strong part of the pattern. What is surprising is that such a point formula would be found in a non-Chinese procedure that has been continuously practised for many thousands of years. It may be that the originators of the tefillin ritual had some inkling of its special effects, even though they may have lacked the depth and specific knowledge we have today.
Regardless of the belief system behind the procedure, it seems clear that putting on tefillin is a unique way of stimulating a very precise set of acupuncture points that appears designed to clear the mind and harmonise the spirit.
In an article for the layman, "Super Charge Your T'fillin: The Secret's in the Wrap" (PDF), Dr. Schram explains how precisely to wrap your tefillin to best stimulate the acupuncture points:
It is important to understand that acupuncture points have very specific locations, and you must be exactly on the point for it to be stimulated. A quarter inch off the position results in missing that point. This means that you must remain aware of where you wrap the retzuah and you must do it carefully. To get the greatest benefit, (because the effects of point stimulation are cumulative), you should wrap exactly the same way every time you don T'fillin.
Donning T'fillin remains a great spiritual mitzvah based on a Torah commandment going back over 3300 years. Because the information presented in this paper is in full accordance with the various Halachic and traditional guidelines, there should be no barrier to the inclusion and application of this knowledge to your ritual use of T'fillin. By stimulating the acupuncture points that already lie along the path of the retzuah, you can bring about a heightened mental clarity to your prayers. The result of doing this can only enhance your mental and spiritual experience, allowing you to fulfill the Mitzvah to its highest degree.
To think all these years I've been receiving daily acupressure treatment without knowing it!
