The Not-self

There has been much written over the millennia about the not-self, but for those unfamiliar with the term, here's a nut shell definition:

There's an awareness that isn't what we think of as our self. We can experience it. We feel connected to it. In fact, it's very familiar and homey, once we open up to it. But whatever it is, it can't be captured or defined.

As the thinker only deals in tangibles, many have attempted to interpret, identify and define it. But even someone with the best of intentions, can't explain physics to a fish.

To my mind, “not-self” implies it, without trying to say what it is, or what our relationship with it is.
