Dharma is one of the hardest Sanskrit terms to translate cleanly — “duty,” “law,” “righteousness,” and “the order of things” are all partial renderings. In BG 2.31, the sense in play is narrower and more concrete: svadharma, one’s own duty, bound to role and circumstance rather than universal.
A role-bound argument, not a universal one
Krishna’s case to Arjuna in chapter 2 is specifically that fighting a righteous war is the duty proper to a kshatriya (a member of the warrior class) — not that fighting is good in some context-free sense. The Gita is explicit elsewhere that svadharma differs by station: what is dharma for a kshatriya is not necessarily dharma for a brahmin. Chapter 2 meets Arjuna inside his own framework rather than asking him to abandon his role.
This is worth holding onto precisely because the verse gets quoted out of context fairly often — as a general argument for “doing your duty,” full stop. In the text, it is doing much narrower work.

Karma (कर्म)
The Gita's technical sense of karma — action itself, and the discipline of acting without attachment to its fruit — distinct from the popular "cosmic reward and punishment" meaning of the word.
Atman (आत्मन्)
The self that inhabits the body in the Gita's second chapter — unborn, imperishable, and untouched by what happens to the body — the metaphysical foundation the chapter's argument for fighting rests on.
Sthitaprajna (स्थितप्रज्ञ)
The "person of steady wisdom" the Gita's second chapter closes with — its technical term for what settled equanimity actually looks like, in mind and action.
Yoga (योग)
In the Gita's second chapter, yoga names a discipline of evenness of mind in action — not a physical practice, and not a single technique — first given this technical sense at BG 2.48.
