Interesting this:
What is personality anyway?
What use is it?
Do we need it?
Does it weigh us down?
Does it mire us in the past, harming our ability to be in the present?
I'll venture a guess from my neck of the woods...
Personality could be seen as basically
person-ality! It is the unique expression of our personhood, our wiring, the many facets of our emotional and other responses to the world we live in. It is amazing to watch personality emerge in a baby...and sure enough 30 years later much of that early makup is still intact!!
I see basic personality as a gift. Yes, we can efface it and skew it, but essentially it is a gift connected to our existance. I like here the maxim that "Grace builds on nature." In this case, our personality would interact with the world no matter how rooted, or wise, or learned, or saintly we may become...the expression is basically coming from this internal hardwiring that is almost impossible to escape. We can inform our personality to be more balanced or healthy...but in the end I think we just have to go with what we have.
Many things in life can hold us back, but I might submit that personality may not be one of them. Our assumptions may be limited, our personhood wounded, our expression of personality limited, but that essense is still there and it is part of our giftedness.
The more common dilemma, it seems to me, is not so much with our personality, but with our false self...a self disconnected from deeper awareness of a more spiritual nature. From early on we see the world as full of lack...if we continue in this mode as we grow we may experience more percieved limitations than we are actually destined for. Connection to spiritual/cosmic truth helps us to see the world as immensely full and without lack. The state of this sense of self could alter how we experience our personality (and everything else), but the self sense is the issue...not our personality per se.
My random thoughts...
