With mindfulness practice we should try to limit judgment of ourselves, others, and the world around us. I have gotten better at not judging myself, and the world, but it still has been difficult not judging others. I recognize that judgment of others is more a reflection of myself, than others.
With mindfulness I have been able to become aware of when I judge others. It starts with awareness. After that, I reflect on why I am making this judgment. It is to compare?, to compete?, to feel superior?, or is it that they don’t fit my standard? It could be all of these things. Remember that the person you are judging has no clue you are doing it, so how productive can it be?
Judging others puts a negative stain on the person judging. It fuels hatred, jealousy, bitterness, and anger. Why do I need to create these emotions when I don’t have to. We can’t stop ourselves from judging. It is an innate human quality, but we can control how much and how long it consumes our lives. Become aware, reflect, learn and move forward. No use in dwelling over something you can’t change, and if you can, say something and take action in a positive and productive way.
