I am not now who I was, nor am I who I hope one day to be. If I cling to now, then, or an image of myself in the future, I am stuck, not free.
I will append to this an encouragement for anyone wanting to ponder in more depth what it really means for any us to “have” a personality, or sense of self, to read William James treatment of these topics in the first volume of “Principles of Psychology”. I would particularly encourage any students of Buddhism or metaphysics generally to look that book up. I myself need to reread it, but suffice it to say most should find it quite interesting, confusing, and perhaps enlightening. Most of us make assumptions which really are not warranted by facts we already have.
