When we talk about self-care, we usually referring to proper diet, exercise and sleep. This is only part of global self-care.
In Zen, however, self-care is an oxymoron. Why?
A fundamental teaching of Zen Buddhism is the concept of “no-self”. No-self does not mean that we don’t exist as living being. This is absurd. It means simply that the self is not a unique, permanent, independent, separate self-entity with a self-intrinsic life. We are all interconnected and interdependent with our environment, which is providing life to us.
