Kural 378 stands in the chapter on fate, and it makes the destitute a witness to fate's power rather than a subject of reproach. Those without the means of enjoyment would renounce, it says, if fate stopped delivering the sufferings appointed for them. Parimelazhagar makes the intention explicit and puts the obstacle outside the man: வறுமையான் நுகர்ச்சி இல்லாதார் துறக்கும் கருத்துடையர் ஆவர் — those who through poverty have nothing to enjoy do have the mind to renounce — and the only thing standing in the way is the condition he then states, ஊழ்கள் உறுதற்பாலவாய துன்பங்களை உறுவியாது ஒழியுமாயின், if fate would leave off inflicting what is allotted. Renunciation is what they would choose. Fate is why they cannot.
Kural 1050, in the chapter on poverty, addresses the same people and blames them. Parimelazhagar's phrasing turns the same act into an obligation: நுகரப்படும் பொருள்கள் இல்லாதார் தம்மாற் செயற்பாலது முற்றத் துறத்தலேயாகவும் அது செய்யாது ஒழிதல் — for those without goods to consume, the thing to be done by them is to renounce utterly, and their failing to do it is what the verse then measures, as death to the salt and the sour rice-water in other people's houses.
What makes the two impossible to hold apart is that the commentator himself supplies the identification. Both verses open with துப்புரவு இல்லார், and he opens both glosses by explaining that phrase the same way — having nothing to enjoy through poverty, having no goods to consume. It is one description of one person. Fate excuses him in the chapter on fate; he is answerable for exactly the same omission in the chapter on poverty.
A settlement can be attempted: one verse explains why renunciation does not happen and the other says it ought to, and explaining a failure is not the same as excusing it. That reading is available. It sits badly with the word Parimelazhagar chose at 1050 — செயற்பாலது, the thing to be done by them — set against the fate he says at 378 prevents it. He wrote both glosses, and he reconciled them nowhere.
