I agree. Concentration and awareness/mindfulness meditation are very different things in my opinion too. For example, I'm able to reach "flow" for sustained periods of time in my work (which is ultimate concentration), but the result of that is completely different than an awareness exercise for even 2+ minutes. This of course is nowhere near proof, but it's my experience: 1. After the intense concentration I nearly feel out of it afterwards, or lower in energy. It feels like I have lost track of where and who in the universe I just was. Depending on the task, I may afterwards feel a certain sense of accomplishment or the opposite, wasteful. 2. After an awareness exercise I get a sense of relief. I feel like I can look upon the world in a less biased way -- see reality for more of what it is. I feel like certain worries and stresses have dissipated, and an overall life-focus has improved -- I can see better than usual what is more important for me and for my life. In addition, my judgments of people and things has dissipated too, become more healthy and realistic. I completely agree a real study would be great though.
