The direction of meditative research
This article is a great introduction to the history of our definitions of mindfulness and where our definition of mindfulness is going both theoretically and neurobiologically. I'm not going to dare to comment on it. But it'll be a great intro for anyone who wants to dig in deeper to what's going on in the brain during mindfullness AND what we really mean by mindfullness. http://www.frontiersin.org/Human_Neuroscience/10.3389/fnhum.2012.00296/full
