Are you wondering how EFT works? To the best of our current understanding, it works by eliminating blockages in the subtle energy (or meridian) system of the body, much like advanced "clot-busting" drugs dissolve clots in our blood vessels.
In EFT our understanding is that when we gently tap on specific places in the body, we are sending kinetic energy down the meridians, and facilitating the release of 'stuck points' in them. If you'd like to learn more about the scientific basis for energy healing, there are some links on the Web Links & Resources page that are very helpful.
Whether your current belief system predisposes you to accept the existence of the subtle energy body or not, we know from today's understanding of quantum physics that everything is energy. Even things that appear solid to our five senses are, when you get down to it, mostly the empty space between the nuclei of atoms and their surrounding electrons.
I think the best way to evaluate the effectiveness of EFT is to try it for yourself with an open mind, using an experienced practitioner, and with as little attachment to the outcome as you can muster. You can then be the judge of your own experience and see whether it helps!
Whether it is our attention to the emotional intensity, our intention to release it, the energy sent through the body by tapping on the meridians, or the way we frame and reframe the issue, we know that EFT creates results over 85% of the time.
And just in case you are wondering, please know that you don't have to re-experience traumatic events! I am careful to apply specific techniques within the framework of EFT to keep the process virtually painless.
