Judging others will avail you nothing and injure you spiritually. Only if you can inspire others to judge themselves will anything worthwhile have been accomplished. When you approach others in judgement they will be on the defensive. When you are able to approach them in a kindly, loving manner without judgement they will tend to judge themselves and be transformed.
