Mindfulness is an ever growing phenomenon. As more and more people look to mindfulness for help, answers or just for relief, it's important to learn the practice from trusted and reliable sources.
The UK's Mental Health Foundation is just one of these sources. I've been using their website for the past three years for high standard information, explanations, as well as their array of free publications. They've been of great help to me particularly when I was involved in mental health education and outreach in college. One such publication, is on Mindfulness.
