Bhagavad Gita, Chapter 18, Verse 11

Actions cannot be entirely relinquished by an embodied being, but he who relinquishes the fruits of action is called a relinquisher.

Krishna names a real, practical limit here, no embodied being can actually stop acting altogether.

Rather than asking for something impossible, real renunciation is redefined around what's actually achievable, letting go of the fruits, not the actions themselves. The goal gets adjusted to fit real human limits.
