படித்தும், படித்தவற்றை உணர்ந்தும், மற்றவர்க்குச் சொல்லியும், அவற்றின்படி வாழாதவரைக் காட்டிலும் அறிவற்றவர் வேறு இல்லை.

படித்தும், படித்ததை உணர்ந்தும், உணர்ந்ததைப் பலருக்கு உணர்த்திடவும் கூடியவர்கள், தாங்கள் மட்டும் அவ்வாறு நடக்காமலிருந்தால் அவர்களைவிடப் பேதைகள் யாரும் இருக்க முடியாது

நூல்களை ஓதியும், அவற்றின் பொருளை உணர்ந்தும், பிறர்க்கு எடுத்துச் சொல்லியும் தான் அவற்றின் நெறியில் அடங்கி ஒழுகாதப் பேதைப் போல் வேறு பேதையர் இல்லை.

There are no greater fools than he who, though he has read and understood (a great deal) and even taught it to others, does not walk according to his own teaching

Kural 834 is a reflection on the application of knowledge and wisdom in one's life. It emphasizes that the true value of learning and understanding is not just in acquiring knowledge or in its dissemination to others, but in living according to that understanding. The verse suggests that even if a person has read extensively, comprehended deeply, and shared that knowledge with others, they are deemed foolish if they do not adhere to their own teachings in their personal life. This could be seen as a commentary on the hypocrisy of preaching principles or virtues that one does not follow oneself. The verse thus underlines the importance of personal integrity and consistency between one's words and actions. In essence, this Kural is a reminder that knowledge and wisdom are not just intellectual exercises, but essentially guides for living a principled and meaningful life. It suggests that the highest form of wisdom is to practice what you preach. Otherwise, such unpracticed knowledge is fruitless and the person holding it is no different from a fool. In a broader cultural context, this verse underscores the strong emphasis on moral and ethical living in the Tamil tradition, highlighting the belief that true wisdom is as much about right action as it is about right understanding.
