Bhagavad Gita, Chapter 18, Verse 60

Fettered, O son of Kunti, by your own Karma, born of your own nature, what you, from delusion, desire not to do, you shall have to do in spite of yourself.

What someone actually resists doing is named here as something they'll still end up doing anyway, driven by real, deeper inclination.

Krishna names this compulsion directly rather than leaving it as a vague warning. Real nature, once again, is shown as more decisive than a real, conscious refusal.
