Mindfulness is very popular at present . It can be more complicated than appears in some descriptions. The author gives a deeper insight and explains ‘Constancy’, a modern explanation of an ancient teaching, where mindfulness is practiced 24/7. Resonant info is also provided. This is the cheapest price Amazon would let me charge, (I make no profit on the paperback version). On the plus side balancing that, this is also a work of reference, with plenty of items to return to over the years. Good luck to all.
