श्लोक कहता है

Having let go of holding on to what his actions bring, always content, depending on nothing — he does nothing at all, even while fully at work.

सरल शब्दों में

The paradox of verse 18, now stated plainly.

He is abhipravṛttaḥ — fully engaged, thoroughly at it. And na eva kiñcit karoti — he does not do anything.

Both halves in the same sentence, and neither is a figure of speech.

आपने इसे कहाँ महसूस किया है

Someone with a long illness who keeps doing everything they can still do. They are not fighting it and not resigned either. The days have stopped being a campaign.

और गहराई में

Nitya-tṛptaḥ — always satisfied. This is the load-bearing phrase and it points back to 2.55's contentment in the self, by the self.

The logic runs: if satisfaction is already present, then nothing you do is being done in order to get satisfied. And if no action is aimed at acquiring anything, then in the sense that matters, nothing is being done at all.

Nirāśrayaḥ — without support, without anything to lean on. It is stronger than it sounds and it matches 3.18's man who depends on no creature for any purpose.

What makes this verse land rather than float is abhipravṛttaḥ. The Gita will not let the reader turn non-attachment into reduced activity. Fully engaged, and doing nothing. Both, at once, in the same person, on the same afternoon.
