One of the pages [1] on The HeartMath site references Dr Bruce Lipton.

If you're interested in understanding more about the interplay between experiences, emotions, physiology and genetics, I can strongly recommend his book, The Biology of Belief [2], and his many interviews and presentations that can be found on YouTube.

His research and writing focuses on the notion that subconscious beliefs are the major influence on our perceptions, which is why for some of us, experiences can trigger pathological health conditions like anxiety and depression, along with auto-immune illnesses and other chronic illnesses that result from chronic stress (which can include cardiovascular disease and other serious conditions).

Inspired by this book, I've had great success improving my emotional and physiological health by undertaking practices that focus on subconscious beliefs. They all seek to achieve similar results to NLP (congruence, non-reactivity, etc), but I've found these ones to be more effective:

- Self Clearing [3]

- Holotropic Breathwork [4]

- Dolores Cannon Hypnosis [5]

All this stuff draws contempt from curmudgeonly skeptics (of which I used to be the worst kind), but from painful experience I've found these techniques to be far more effective than any of the more conventional approaches I'd tried previously.

I can also recommend Stoic Philosophy [6], but for me these practices are tools and systems that enable concepts from stoicism to be implemented most effectively.

The basis for the approach I've pursued came from a book called The Biology of Belief [1], by former Stanford stem-cell researcher Bruce Lipton. The book is about epigenetics, and the way environmental factors - particularly the influence of subconscious beliefs on the perception of your environment, can influence physiological health. I found it compelling and I seem to have benefited by pursuing the ideas, but it's not for everyone; despite his scientific background his primary audience these days is the New Age market, and I know his way of articulating his ideas is too woo-woo for many. But he is entertaining.

The method I've used for trauma clearing is called NET [2] which came out of the chiropractic world, but I've since learned how to do it myself so I no longer need to spend money on chiropractors, most of whom I now regard as quacks.

The closest version of the technique I now use is a method called Self Clearing, demonstrated in this video [3] by an Australian guy called Dane Thomas.

I'm well aware that all this stuff will seem like quackery to many; as a former devotee of Dawkins and Hitchens, it sure did to me, but my ongoing health struggles necessitated a willingness to try anything, and of the many things I tried, this has been the one that's delivered results.
