Pollaadha solluvan nalavar enpaan
Solluga nalldhoor sol.
Let the one who would speak something bad instead speak one good word.
தீயது சொல்ல நினைப்பவன் நல்லது ஒன்று சொல்லட்டும்.
The simple prescription: whenever the impulse for harmful or useless speech arises, replace it with one good word. The discipline of substitution — replacing bad speech with good — is more practical than simply suppressing speech.
