The thing that I have been studying about this month is called EFT, or just "tapping". While it is kind of a novel idea when you first read about it, there are a lot of great testimonials to how well it works......... Even when you don't believe it will work. Faith is not required for EFT to work. Most of us have heard of the ancient healing methods of acupuncture, and know that a knowledgeable acupuncturist can do wonders towards healing many different ailments. Acupuncture works by stimulating what are called "meridians" in different areas of the body, depending on what result it is being applied for. Tapping works on the same principle of stimulating the meridians; but there is no use of needles or any other instrument except for your own fingertips. I have been reading about this, and watching some of the youtube videos to learn how it works and be able to start using it on myself. I think that I need to learn more; but just the amount that I have been using it; I am able to walk better with the bad knee, and I intend to use it for other issues as well once I get a little more proficient. It is actually very simple to learn to do, there are several areas on your face and chest that you tap on, as well as the wrist and top of your head; so understanding the mechanics of tapping is easy. What I am still learning is how to apply it better in more problem areas of my life/body. Here is a short introductory video that explains basically how EFT works.
