“Don’t judge” simply means that no action gives us the right to condemn another person. If the action is not right, help the person to find out the reason. Don’t take the person’s dignity, don’t humiliate him and don’t make him feel guilty.
We naturally judge ourselves because we crave for the perfection which doesn’t exist from the first place. We dwell on that imperfection and retaliate with ourselves and the the whole world. This leaves us with only one idea and that is to find imperfection in everybody.
How we treat others is a direct extension of how we feel about ourselves; how we treat ourselves and vice versa.
Once we stop judging ourselves and accept ourselves, we will be able to accept others also because we will have a clear insight that they are suffering from the same disease. Our accepting them will help them to accept themselves. They learn the beauty of acceptance for the first time; how peaceful it feels and they start accepting others. If the entire humanity comes to a point where everybody is accepted as he is, almost ninety percent of our misery will simply disappear.
