"Judging Favorably

"One Shabbat, during the third meal, the Baal Shem Tov taught his disciples, saying: 'Don't judge someone else, because you have the same fault in yourself. Learn to judge other people favorably, since loving your neighbor as yourself is a great principle of the Torah and the basis for all spiritual perfection. How can you love another person when you are judging him? So when you see someone sinning or acting wrongly, or hear people talking about another person's sin or wickedness, consider it as certain that there is at least a trace of that same sin in you, and God has brought this seeing or hearing before you to remind you of your fault and to that you will repent, for your responsibility is to fix what needs fixing in you."
