First of all I have to say that i despise calling something scientific work that is clearly way more subjective than mesaurable like science. For example question: does this engine spend less fuel than one before is clear way to show was that invention good or not, do you have better wellbeing after some treatment is completely open for placebo effect and can't be in same category. IMO meditation 'science' if it ever wants to be true science should concentrate on mesaurable mental qualities like IQ and memory. So true science question should be: how large is your IQ score before and after meditation retreat or how much you can remember things in 2 min before and after. Everything other is not science and is higly debatable. Honestly I'm quite suprised that engineers spend so much time on so unproved technique to increase quality of their work and life.
