Prof Jon Kabat-Zinn: "Paying attention, on purpose, in the present moment, non-judgementally" also "when we speak of mindfulness, it is important to keep in mind that we equally mean heartfulness. …in Asian languages, the word for “mind” and the word for “heart” are usually the same. …it is a way of being”. Jon Kabat-Zinn, Full Catastrophe Living (2013), Pg. xxxv; 2ndedn., Piatkus

Prof Mark Williams (MBCT): "Well mindfulness really is the word, but really simply means awareness – awareness of what’s happening as it’s happening both in the inside world and the outside world. It comes from a very ancient word, but it’s probably easiest to understand if you think of its opposite mindlessness. Mindlessness – where you keep forgetting to do things, you don’t listen properly, you’re not attending properly, the world is going by without you really being there for it or here for it and mindfulness is the awareness that emerges when you make a decision to train your mind, to some extent, to check in more often to how things are..." https://mrsmindfulness.com/an-introduction-to-mindfulness-melli-obrien-interviews-prof-mark-williams/
NICE : National Institute for Health and Care Excellence. "Mindfulness is a way of paying attention to the present moment, using techniques like meditation, breathing and yoga. It helps the individual to become more aware of thoughts and feelings so that, instead of being overwhelmed by them, we are better able to manage them." https://www.evidence.nhs.uk/document?id=1611497&returnUrl=search%3fq%3dmindfulness&q=mindfulness
The National Institute for Health and Clinical Excellence (NICE) is an agency of the National Health Service charged with promoting clinical excellence in NHS service providers in England and Wales, by developing guidance and recommendations on the effectiveness of treatments and medical procedures.
Thich Nhat Hanh explains, “Mindfulness is to be aware of what is going on…Mindfulness is always mindfulness of something… mindfulness can be practised at every moment of your daily life… you cultivate the energy of mindfulness and this is the energy that can bring about the energy of concentration and insight… insight is liberating”.
