Innocent and fair criticism does not hurt and is good, but it is quite rare. What I mean by talking ill of others is when you criticize and it hurts; it hurts when you criticize excitedly, out of anger. When you criticize with love and kindness, how can it hurt?
… Any remark or criticism that does not hurt is good. Make fun, joke, humor, but don’t hurt anyone and talk back. If you point out the shortcomings of others lovingly, without any feeling of hate or animosity, it is all right. Even arguing with love is permitted. Try your utmost to help me, which you can do by acting according to my wish. Sacrifice your sweet habit of hurting others. Fight to overcome lust, anger and greed. To control is not to do that which you have been used to doing.
