Kural 276 does not describe hypocrisy mildly. Of everyone alive, it says, none is harder of heart than the man who holds attachment in his mind, carries himself as one who has renounced, and lives by deceiving. Parimelazhagar makes the deceit concrete rather than abstract: the man lives பறறற்றார் போன்று தானம் செய்வாரை வஞ்சித்து, appearing detached and cheating the very people who give alms. Chapter 28 is built on one definition of the vice — the inner state and the outward form deliberately pulled apart.
More than five hundred verses later, that same arrangement is issued as instruction. When enemies come to behave as friends, says 830, meet them with friendship in the face and drop the friendship from the heart. The verse before it goes further: keep them pleased outwardly, stay inside the alliance, and let it die within. What Chapter 28 defines as the worst hardness of heart, Chapter 83 sets out as the posture a ruler should adopt.
Parimelazhagar does not deny the collision. He relocates it. He closes his gloss on 829 with a single word that changes the register of everything before it — அரசநீதி, the way of royal policy — so that the counsel is not a rule of character but a rule of statecraft. And on 830 he adds a limit the Tamil does not contain: அகத்தால் அதனைவிட்டுப் பின் அதுவும் தவிர்க. Withdraw inwardly, and afterwards give up even the outward show. The verse says only the first half; the second half is the commentator's.
He never goes back to 276. Nothing in either gloss explains why the posture that makes a man the cruellest person alive in Book 1 becomes a method in Book 2, and the division by domain is offered as a placement rather than argued for. That is what a reader is left holding: an answer about where each verse belongs, and none about how both can be true.
