Do not regard the feelings of a person who speaks to you about his neighbor disparagingly, but rather say to him: "Stop, brother! I fall into graver sins every day, so how can I criticize him? In this way you will achieve two things; you will heal yourself and your neighbor with one plaster. This is one of the shortest ways to the forgiveness of sins; I mean, not to judge. Judge not, and ye shall not be judged."
