Bhagavad Gita 18.49

असक्तबुद्धिः सर्वत्र जितात्मा विगतस्पृहः।नैष्कर्म्यसिद्धिं परमां संन्यासेनाधिगच्छति॥

asaktabuddhiḥ sarvatra jitātmā vigataspṛhaḥ |naiṣkarmyasiddhiṃ paramāṃ saṃnyāsenādhigacchati ||

He whose intellect is unattached everywhere, who has subdued his self, from whom desire has fled, he attains the supreme state of freedom from action through renunciation.

He whose mind is entirely detached, who has conquered himself, and whose desires have vanished, reaches that stage of perfect freedom through his renunciation, where action completes itself and leaves no seed.

Our plain-language meaning of this verse is waiting for scholar review.
