Nirai mozhi maandhar perumai nilathu
Marai mozhi kaatti vidum.
The Vedas (sacred scriptures) will reveal the greatness of perfect-worded persons (sages) to the world.
நிறைந்த சொற்களை உடைய சான்றோர்களின் பெருமையை மறைகள் (வேதங்கள்) இந்த நிலவுலகில் காட்டி நிற்கும்.
The sages' greatness is proven and preserved by the sacred scriptures themselves. Their words and the Vedic words align — the sage's speech has Vedic authority. This kural gives renunciants their highest credential: the Vedas themselves testify to their greatness. Perfect speech (niraimozhi) = Vedic truth.
