Bhagavad Gita, Chapter 4, Verse 19

Whose undertakings are all devoid of plan and desire for results, and whose actions are burnt by the fire of knowledge, him, the sages call wise.

Real understanding doesn't just inform action, it actually changes what that action leaves behind.

This describes a real, tangible shift, not just a mindset. Once genuine insight takes hold, the usual residue that comes from acting out of craving simply doesn't accumulate the same way anymore.
