Jñāna Yoga · Verse 20
त्यक्त्वा कर्मफलासङ्गं नित्यतृप्तो निराश्रयः | कर्मण्यभिप्रवृत्तोऽपि नैव किञ्चित्करोति सः
tyaktvā karma-phala-saṅgaṃ nitya-tṛpto nirāśrayaḥ | karmaṇy abhipravṛtto 'pi naiva kiñcit karoti saḥ
Having abandoned attachment to the fruit of action, always satisfied, independent, though undertaking actions, in truth he does nothing.
Characteristics of the nitya-tṛpta — always satisfied. Tyaktvā karma-phala-saṅgam — having abandoned attachment to fruits — does not desire results.
Nirāśrayaḥ — without dependence — does not seek external support. Abhipravṛttaḥ — undertaking — describes external action. But na kiñcit karoti — he does nothing — because without egoistic intention, without karmic seeds. It is action liṅga — without residue.
