Krishna is describing the person who has genuinely let go of ego-driven wanting. Having defined the wise, unattached actor in the previous verses, he now sketches the simplest possible version of that life in action.
nirāśīr yata-cittātmā tyakta-sarva-parigrahaḥ | śārīraṃ kevalaṃ karma kurvan nāpnoti kilbiṣam ||
Free from desire, with mind and self restrained, having abandoned all possessiveness, performing only the bodily (minimal, necessary) action, such a person incurs no wrong or stain.
After several verses about the mechanics of offering and sacrifice, this verse lands at the plainest possible statement: act without wanting, without scattering, without hoarding, and the action leaves no residue. No theological complexity. Just the direct behavior.
The verse equates letting go of possessiveness not just with material non-attachment but with something subtler. The self that accumulates accomplishments, titles, outcomes, and recognition is doing the same thing as the miser hoarding coins. Both are trying to build a secure self out of acquired things. The verse says: put it all down.
Śārīraṃ kevalam is not a prescription for doing the minimum at work. It is pointing at motive, not output. The person may work intensely. But they are not adding the invisible second layer of ego-labor: the performing, the positioning, the managing of how the work looks. Strip that layer off, and what remains is clean action.
The logic is mechanical and exact. Karma accrues when the actor is present in the action as a claimant: 'I did this, therefore I deserve that.' Remove the claimant, and the causal chain that would have bound the next moment does not form. Not as a reward for good behavior, but as a simple consequence of the structure.
Person A ships a product feature, but half their energy has gone into making sure the right people saw them doing it, making sure the credit is legible, anxiously tracking the reception, building the narrative around it. The work is done but it leaves a residue: a score to settle, an image to maintain, a next move to manage. Person B does the same work. Same quality, same intensity. But when it ships, they have no account they are keeping. No debt owed to them, no image to protect. The next task can arrive fresh. The work was complete the moment it was done.
Verse 22 extends this portrait: the person who is content with whatever comes by chance, who has moved past envy of opposites, and who acts with equal steadiness in success and failure. When ready, say: "4.22"
