Thank you for your comment Monica. In my comment, what I tried to convey was that mindfulness is not dangerous or risky IF it is properly understood in terms of what exactly it is, what it is doing and how it can benefit different people in different ways. Also it should be noted that lots of research has demonstrated that neurogenesis (the generation of new neurons in the brain) can happen after traumatic brain injuries and also that mindfulness meditation promotes neurogenesis. So, I don’t see any reason to believe that a brain that is ‘heinously injured by drugs’ cannot overcome any damages that may have happened due to drugs. Through mindfulness practices, one can even overcome worrisome thoughts like “for me life is heinously bumpy and risky” without letting such thoughts overpower their lives. All the best for your potential book!
