MSZ talks about the heart wall. This is from the link she posted above regarding the heart wall and a message from the creator of the Emotion Code:

I believe that the single most important thing you can do for yourself is to get rid of the trapped negative emotions that are forming that “wall” around your heart. The Emotion Code is the only way that I know of to do this. It is the simplest, most efficient method of releasing trapped emotions ever devised. It is easily learned by anyone, without any previous training. The release of trapped emotions is permanent, and it works for all ages.

"The only way we can change this world and bring it to a higher level of civilization is through changing the inhabitants of this earth, one at a time. By helping people to shed their emotional baggage, we transform them back into the pure spirits that they should be, and they become empowered to become who God intended them to become; their pains and phobias, their addictions and self-defeating behaviors fall away, and the pure essence of each individual shines forth from each heart, filling the immensity of space. This is how the world will change; and I guarantee you, it will, one person at a time. I hope you will join me and become a part of this work, whose destiny is to help transform this earth to a higher plane of existence, one life at a time!”
