For some background, here is an article about my past work at University of Pittsburgh Medical Center. 

The first time I met one of my master teachers, he said to me in his special way. "Mark, what you do is very good. You help a lot of people and don't need to be any better...but what you do is not very profound."

I was not offended nor did I argue.  I knew he was correct. When I read all the talk of mindfulness and neuro plasticity, or that yoga is a 7 billion a year industry, or that Google has mindfullness classes, or the Hapiness Project is selling books....

I know I did the right thing in quitting.  What I was doing was not profound enough. My practice was not deep enough.  

Think of it this way. You go to a five star restaurant and eat something unbelievable. Then you go out on a lecture circut telling everyone about it.  You still did not and cannot cook the meal.
