நாய் குரைத்தாலும் நிலவுக்கு ஒன்றும் ஆகாது
Naai kuraiththaalum nilavukku onrum aagaadhu
Meaning
No matter how much a dog barks, the moon doesn't dim - petty criticism can never diminish something truly great.
Story
When an artist released her new work, a few people criticized it without real reason. She stayed unshaken. Years later, that very work became known as her finest achievement - the barking had long gone quiet, while the moon kept right on shining.
Reader's Note
Not every criticism deserves a response - let your work speak instead.
