|| 3.18 ||

नैव तस्य कृतेनार्थो नाकृतेनेह कश्चन। न चास्य सर्वभूतेषु कश्िचदर्थव्यपाश्रयः।।

naiva tasya kṛtenārtho nākṛteneha kaścana na cāsya sarva-bhūteṣu kaścid artha-vyapāśrayaḥ

na (never) eva (certainly) tasya (his) kṛtena (by discharge of duty) arthaḥ (purpose) na (not) akṛtena (by not performing duty) iha (in this world) kaścana (whatever) na (never) ca (and) asya (his) sarva-bhūteṣu (among all beings) kaścit (any) artha (purpose) vyapāśrayaḥ (taking shelter of)

A self-realized man has no purpose to fulfill in the discharge of his prescribed duties, nor has he any reason not to perform such work. Nor has he any need to depend on any other living being.

Elaborating on the self-realized soul, Kṛṣṇa says that such a person has nothing to gain by performing their duty and nothing to lose by skipping it. They are completely independent of all other living beings for their happiness or survival. A liberated soul is like a person who has already arrived at their destination; they don’t need the map or the vehicle anymore. They don’t follow rules out of fear of punishment or hope for reward. They are truly free. They don’t rely on anyone else for their internal sense of peace. Kṛṣṇa mentions this state to show Arjuna the ultimate result of Yoga. But the implication remains that Arjuna is currently dependent on his relatives and his status for his happiness. Since he is not yet at this stage of total independence, he must stay on the path of regulated duty to reach it. True freedom is earned through disciplined action.
