Bageshwar Dham Sarkar
Why is speaking ill of others considered so low?
Criticism is cleaning filth with the tongue
A mother cleans a child's filth with her hands, but one who criticises cleans filth with the tongue. That is why critics are called pigs, and he says this is what people say.
The one who criticises also cleans filth, but with the tongue; that is why he is called a pig.
