I have internal conversations all the time, throughout the day, and I find that I argue less and less as I become more aware. Less to prove, I suspect, but also the knowing that any stand I take in an argument is temporary at best and most certainly foolish in any case.
Don't ask me today to defend something I said yesterday. I will have changed a thousand times in a million different ways since then.
So I have no need to argue with a critic or defend a particular statement of mine. It was simply an expression of my understanding at that time, nothing more. Nothing to prove or dispute or refute.
If you choose to criticize or judge me, I know you are doing so as a result of YOUR beliefs, not mine.
Therefore, I have no need to argue with you. Nor, for that matter, do I have a need for you to agree with me.
Of course, it took me many years to realize that. And it will take many more to live my life that way.
