Since the term arose in 1950's, "self-care" has referred to a number of different things. If we consider self-care to be things you do to remain physically and mentally healthy, then Zazen – simple, goalless, Zen meditation – can be seen as excellent self-care. In these troubled times, such self-care can even be seen as defiant – refusing to be broken down by challenging circumstances. Other forms of meditation can also be seen as self-care, of course, but Zazen can be a little difficult to get your mind around. Framing it as self-care may help you appreciate what it's all about.
