The verse says

The person who gives up wanting and goes about without craving, without "mine", without "I am the one" — that person comes to peace.

In plain words

Three things dropped, and the last two are the deep ones.

Niḥspṛha — no craving. Nirmama — no mine. Nirahaṅkāra — no I am the one doing this.

That middle word is the one that answers Chapter 1.

Where you've felt this · in creative work

You hand over a project you built and watch someone else change it. There is a version of you that would have found that unbearable. You notice, mildly, that you have no stake in it any more.

Going deeper

Nirmama — without mine. Trace that back to where this book started.

Dhritarashtra's very first word in Chapter 1 was māmakāḥmy men — and it split one family into two armies. Duryodhana said mama sainyasya, my army. Arjuna collapsed over sva-janam, my own people. The entire first chapter runs on possessive pronouns.

So when Krishna names nirmama as a condition of peace, he is not introducing a new idea at the end of a chapter. He is closing a circuit that was opened in the book's opening line.

Nirahaṅkāra — without the I-maker. Ahaṅkāra is literally the I-doing faculty, the thing that stamps ownership onto an action. This is what was crushing Arjuna: not the deaths, but being the one whose hand it was.

And notice that the verse keeps the person moving. Carati — he goes about, he lives. Nothing here describes withdrawal from life. What has been removed is not activity but the apparatus that claims it.
