Im wondering the same thing. It is also offered here to me for free with the clinic that I go to. My T has managed to give me homework and mindfulness is part of what I am supposed to do. Not really sure how to do this but I have to give it a try. She told me to sit in a busy area with everything going on around and instead of being took in by one thing that would normally catch my attention to listen and monitor other things going on as well. Just sit with my eyes closed and listen to the things I normally miss out on.
