The process of comparison and condemnation prevents you from observing, studying. So a real student is one who observes everything in life, outwardly as well as inwardly, without comparing, approving, or condemning.
Someone is being judgmental when their judgments are power-driven, unempathetic, based on their own idiosyncratic values or tastes, overly based on other people’s character, and are closed, shallow, and pessimistic, and ultimately have the consequence of making the other person feel problematically diminished.
Life is better than death, health is better than sickness, abundance is better than want, freedom is better than coercion, happiness is better than suffering, and knowledge is better than superstition and ignorance.
"Never judge a man without putting yourself in his place." This old proverb makes all judgment impossible, for we judge someone only because, in fact, we cannot put ourselves in his place.
