Arivilan nenjatthul ondro arivilan
Sollum sol alla sol.
Does one thing reside in the foolish man's heart? The foolish man speaks words that should not be spoken.
அறிவிலானின் மனதில் ஒன்று உள்ளது; அவன் சொல்லலாகாத சொற்களை சொல்கிறான்.
The foolish person has one characteristic thing in their heart (improper desire) and it shows in their speech — they say what should not be said. The connection between improper inner state and improper outer speech is direct. The cure is inner purification, not outer speech management.
