Chapter 4, Verse 21
Part of 4: Jñāna Karm Sanyās Yog — ज्ञानकर्मसंन्यासयोगनिराशीर्यतचित्तात्मा त्यक्तसर्वपरिग्रहः। शारीरं केवलं कर्म कुर्वन्नाप्नोति किल्बिषम्॥
nirāśhīr yata-chittātmā tyakta-sarva-parigrahaḥ śhārīraṁ kevalaṁ karma kurvan nāpnoti kilbiṣham
Without hope, controlling the mind and the self, having abandoned all covetousness, and performing only bodily actions, one incurs no sin.
The liberated sage renounces all actions except what is necessary for the bare maintenance of the body. He has abandoned all possessions. He incurs no sin which will cause evil effects. For a man who thirsts for liberation (Mumukshu) even righteous activity (Dharma) is a sin as it causes bondage to Samsara. Dharma is a golden fetter for him. A golden fetter is also a fetter. A sage is liberated from both Dharma and Adharma, good and evil or virtue and vice. (Cf. III.7)
