What we mean by the term happiness has always been an interesting topic in every mindfulness practice or Buddhist group I've been in which is why I posted this here. This 35 second video (which will loop until you stop it) is by a geriatric psychologist whose entire practice is about supporting people caring for loved ones with dementia. Her Dementia Careblazers YouTube channel became important to me when I was a dementia caregiver and her comments here exactly mirror my own experience.
In mindfulness circles all around the world we often express the wish "May all beings everywhere be happy." That's been done in Buddhist groups for literally millenia. Like many, when I first heard this, I was a little put off thinking that being "happy" was something that came and went, and seemed a bit superficial. Over the years I've become less interested in getting others to conform to my understanding of things. Now I take the wish to be happy to simply be a wish for the well-being of myself and others. That change turned out to be easier and more useful than convincing the rest of the world to follow my idiosyncratic understanding of a word and relieved me of need to feel disgruntled about terminology.
