Bhagavad Gita, Chapter 6, Verse 1

The Deity said: He who performs his bounden duty without leaning to the fruit of action, he is a renouncer of action as well as of steadfast mind: not he who is without fire, nor he who is without action.

Real renunciation was never about what someone stopped doing, it's about what they stopped needing from it.

Krishna opens this chapter by correcting a common assumption. Giving up rituals or activities on the outside doesn't automatically make someone a renunciate, letting go of the craving for a personal payoff is what actually earns that title.
