Premanand Maharaj Ji
Why does criticising others feel enjoyable, and what do I really get from it?
Criticism pleases only an impure mind
Criticism feels good only to an impure mind, while a pure mind is pained by it. Criticising others gains nothing and brings their sin on your head.
Criticising another gains you nothing, and you must take the sin of the one you criticised on your own head and go to hell.
