18.47

"Fifth, there are sentient beings who are stammering, mute, and unable to speak. When they have something to say, they close their eyes, raise their hands, and cannot speak clearly. What sin brought this about?" The Buddha said: "In their past lives, it was due to slandering the Three Jewels, disparaging the noble path, discussing others' merits and faults, finding flaws in people, falsely accusing the good and honest, and envying and hating the worthy. Therefore they incurred this sinful retribution."
