श्लोक कहता है

Knowing is covered over by this constant enemy of the wise, Arjuna — a fire in the shape of wanting, and it never fills up.

सरल शब्दों में

The image sharpens. Wanting is a fire.

Duṣpūreṇa analena — by fire, hard to fill. That is the whole problem in two words.

And nitya-vairiṇā — the perpetual enemy. Not an occasional lapse. A standing condition.

आपने इसे कहाँ महसूस किया है

You get the thing. There is a clean, real satisfaction, and it lasts about a fortnight. Then the level is exactly where it was, and something else has moved into the space.

और गहराई में

Fire is the right image and it is chosen for one property: fire is the only thing that grows when you feed it.

Every other appetite has a stopping point. Hunger ends with a meal. Fire does not end with fuel — it enlarges. Duṣpūra, hard to fill, is a polite way of saying impossible.

Which answers a question the chapter has not asked out loud. Why does satisfying a desire not reduce the amount of desiring? Because satisfaction was never what was happening. Capacity was being built.

Jñānino nitya-vairiṇā — the constant enemy of the wise. That phrase is doing careful work. It is not saying the wise are especially afflicted. It is saying this remains an enemy even for them, which is 2.60 and 3.33 arriving a third time.

The Gita keeps insisting on this. Understanding is real and it does not make you immune, and a teaching that pretended otherwise would be setting its readers up.
