Premanand Maharaj Ji
निंदा असल में क्या है?
दोष देखकर उनका वर्णन करना निंदा है
Nindā is seeing others' faults and then describing them. Both speaking and hearing it are a great sin.
Seeing others' faults and describing them. Merely seeing their faults without speaking is called par-dosh darshan; when you describe them, it becomes nindā.
