Without expectations for the future, and with the mind and the self controlled, having abandoned all covetousness, doing mere bodily actions, he incurs no sin.
Commentary:
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 an obstacle as it causes bondage to Samsara. Dharma, to him, is a golden fetter for him. A sage is liberated from both Dharma and Adharma, good and evil, virtue and vice. (Cf. III. 7)
