Premanand Maharaj Ji
Why should I stop gossiping and criticising others?
What to do when you see a fault
When a fault shows, bow to Bhagwan, don't criticise, and work on correcting yourself. If a friend's mistake needs to be mentioned, speak only to that person, in private.
If you see faults, go straight to the cause. The cause is Bhagwan. So bow to Bhagwan, and do not look at faults.
