Bhagavad Gita, Chapter 16, Verse 10

Filled with insatiable desires, full of hypocrisy, pride and arrogance, holding evil ideas through delusion, they work with impure resolve.

Real, insatiable craving is named here as never actually satisfied, no matter how much is gained.

Krishna describes a hunger that keeps growing rather than resolving, tied to false beliefs that only deepen the problem. Real dissatisfaction is shown as built into this whole pattern.
