If you sin yourself and grieve even unto death for your sins or for your sudden sin, then rejoice for others, rejoice for the righteous man, rejoice that if you have sinned, he is righteous and has not sinned.
If the evil-doing of men moves you to indignation and overwhelming distress, even to a desire for vengeance on the evil-doers, shun above all things that feeling.

Context

“bring your offering even then and praise God in your loneliness. And if two of you are gathered together—then there is a whole world, a world of living love. Embrace each other tenderly and praise God, for if only in you two His truth has been fulfilled. If you sin yourself and grieve even unto death for your sins or for your sudden sin, then rejoice for others, rejoice for the righteous man, rejoice that if you have sinned, he is righteous and has not sinned. If the evil-doing of men moves you to indignation and overwhelming distress, even to a desire for vengeance on the evil-doers, shun above all things that feeling. Go at once and seek suffering for yourself, as though you were yourself guilty of that wrong. Accept that suffering and bear it and your heart will find comfort, and you will understand that you too are guilty, for you might have been a light to the evil-doers, even as the one man sinless, and you were not a light to them.” source
