Emotional Freedom Technique is so called because it works on the emotions by releasing the initial block of energy within you. To understand why you tap on these chosen points it is good to understand the emotion behind the points as it were and why it works.
Below I have done a presentation to show the position and emotion of the points followed by an article from Brightspace.
Tapping is a easy medium to work with as long as you focus on the emotion in hand. Release does come, perhaps not instantly, but it will come. If struggling for a good result you may be Psychologically or Polarity reversed. See link below.
Presentation of the Points
Release your fears with this simple technique.
Link to Psychological/polarity reversal
Release yourself from Sad to Happy. Tap, tap tapping.
As usual if you choose to act on my experiences you must take full responsibility for your own health.
