Bhagavad Gita 4.20

त्यक्त्वा कर्मफलासङ्गं नित्यतृप्तो निराश्रयः।कर्मण्यभिप्रवृत्तोऽपि नैव किञ्चित्करोति सः॥

tyaktvā karmaphalāsaṅgaṃ nityatṛpto nirāśrayaḥ |karmaṇyabhipravṛtto'pi naiva kiñcitkaroti saḥ ||

Having abandoned attachment to the fruits of the action, ever content, depending on nothing, he does not do anything even while being engaged in activity.

Having surrendered all claim to the results of his actions, he is always contented and independent; in reality, he does nothing, even though he appears to be acting.

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