Chapter 5 · Verse 13
Krishna is dismantling the idea that the self is the doer. Here he introduces a striking image: the body is a city of nine gates, and the self inside it neither acts nor triggers anything.
sarva-karmāṇi manasā sannyasyāste sukhaṃ vaśī | nava-dvāre pure dehī naiva kurvan na kārayan ||
1.Plain meaning
Having mentally renounced all actions, the self-controlled one rests in happiness within the body (the nine-gated city), neither acting nor causing action.
2.Line by line

naiva kurvan na kārayan
3.What is really happening
A.The image does the heavy lifting
Krishna does not argue this point abstractly. He gives you a picture: a walled city with nine gates and someone living inside it quietly. The city is loud and active. The inhabitant is still. The image works because you already know the feeling of being calm while everything around you is moving fast. He is saying that is not the exception. That is your actual nature.
B.Mental renunciation is the harder thing
Dropping physical activity is easier to do and easier to fake. Dropping the mental claim to be the doer while still acting fully is the harder, realer thing. The person who acts completely and does not cling to the results as personal achievement or personal failure is operating from a different interior position than the one who does the same acts while gripped by ownership of them.
C.The nine gates are a diagnostic
The city image is also a practical map. If you want to notice where identification sneaks back in, watch the gates. At the moment of hearing something critical, or seeing something beautiful, or tasting something you crave, the self gets recruited into the transaction. The senses pull attention outward, then the reactive mind grabs it and says 'this is happening to me.' The practice is to notice that grab.
D.Neither acting nor causing: a counter-intuitive hierarchy
Ordinary understanding puts the self at the top of the action chain: I decide, I cause, things happen. Krishna inverts this. The self is not the cause; it is the witness of causes. The body and mind are instruments through which the world acts on itself. This is not fatalism. The instruments can be refined, directed, mastered. But they are not you.
4.Modern parallel
Person A is a startup founder during a crisis. Every fire that breaks out is personal. Every failure is a statement about who they are. Every success needs to be claimed loudly. The mental load of being the author of everything is crushing, and they are also terrible in a crisis because all their bandwidth is spent on self-protection. Person B runs the same company in the same crisis. They are completely engaged, totally present, making fast decisions. But they are not carrying the identity of 'the person who caused this' or 'the person who fixed this.' The work moves through them without the constant weight of ownership. They act more cleanly because they are not simultaneously managing their own story about the action.
→What comes next
The next verse sharpens the metaphysics: Krishna explains that the lord of the city (the self) does not create either agency or actions or the connection between actions and results. That work is done by nature alone. When ready, say: "5.14"
