My feeling is that we strip it back to Mission Statement and Vision Statement that is simple and appeals to all. Also one that is memorable. The how, what and why can be incorporated in to a set of Core Values. I also think it is important that we mention Meta-health in these statements. Could we test these on people who don't know anything about Meta to see what their perception is? 
My suggestions:
===MISSION statement=== – (what we do and for who)
Empowering people to gain freedom from illness and disease by using Meta-health to self-heal.
===VISION Statement ===(future objective – ultimate goal)
Our dream is a world where all people know that we hold the power within ourselves to heal and restore the balance of health.
===CORE VALUES===
We believe that we all have the ability to heal ourselves
We believe that by finding the root cause of a disease and releasing the emotions and challenging beliefs we can find a way to heal
We are dedicated to collaborating with conventional and traditional medicine to enable us to find new ways of healing
We want the knowledge about Meta-health to be accessible to everyone
We believe that by using scientific knowledge and allowing nature to run its course there can be less suffering and pain in the world
To get our message across we commit to training and supporting Meta-Health practitioners to the highest standards possible
