It is a powerless thing to truly understand that one is not qualified to judge when you do the same things you judge them on. But such a realization does not strip one fully of the need to judge. One still flirts with the idea.
Non-judgmentalism can feel disempowering and weak, but can one make something else in the place of judging others? Can one replace the need to judge with changing one’s mind? So, one is fair and consistent with the reality that one does the things one judges others on, but even goes further: in seeing the good rather than what’s flawed and wrong. Of course there will be flaws and wrongs, but love always believes the best.
