In particular, I think anyone will benefit from removing their Heart Wall. When I removed mine, I noticed an immediate willingness and desire to connect with others. and it did not take long for my relationship with my husband to reach a higher vibration.
The Body Code and Emotion Code system is easy to learn. You need to train yourself in an energy self-test that gives you access to your unconscious mind where a lot of information is stored. You then use the test to ask yourself questions that can have yes or no answers, until you find out what you need to know.
Marvelously detailed, Dr Nelson's system gives you access to the minutiae of your life's emotional history. For example, I discovered that a lump behind my left knee had its origin in the hostility of a gym teacher I had in in 8th grade. Over the years other emotional energies had tangled around the wound. It took me half a day to unravel all the tangles, but at the end the painful lump - which had been there for years - was about 90% gone and within a few weeks was gone altogether. It's interesting that the bump was on Gallbladder 34, the Systemic Point for tendons and ligaments - and boy has that shown up in my health over the years! Remember that with the system you are altering the makeup of the Energy Body and the changes may take time to manifest in the physical body.
The downside of this system is that it is tedious and painstaking. I have occasionally found situations in someone's energies that would have taken hours to remove with the Body Code but that yielded to a 10-minute chakra clearing, leaving only a few residual tangles for the Body Code to unravel.
Body Code and Emotion Code are, like almost all Energy Medicine, easy to practice at a distance.
