What is nishkama karma in the Bhagavad Gita?

Nishkama karma — literally “desireless action” — is the specific discipline Krishna teaches in chapter 3 of the Bhagavad Gita, and it answers a problem chapter 3 raises before it solves it. Arjuna wants to withdraw from action altogether rather than fight; Krishna first blocks that exit. In 3.5 he says, “There is no one who can remain without action even for a moment; indeed, all beings are compelled to act by the qualities born of nature.” Renunciation of action isn't actually available to an embodied being — the body and mind keep acting regardless. So the real choice isn't between acting and not acting; it's about the inner posture you bring to action you can't avoid anyway. That posture is nishkama karma. In 3.19, Krishna states the formula directly: “Therefore, giving up attachment, perform action as a matter of duty, for by working without attachment one attains the Supreme.” The craving for a particular outcome, not the action itself, is what entangles a person; strip the craving out and the same act stops binding. Krishna then offers a working example rather than an abstraction: in 3.20, he points to King Janaka, who “attained perfection by action alone,” performing his royal duties fully while remaining inwardly free, in part to model the discipline for others rather than out of personal necessity. The chapter's larger argument is that nishkama karma isn't passivity dressed up in Sanskrit — it's full, skillful engagement with duty, minus the part of the mind that keeps score.
