श्रेयान्स्वधर्मो विगुणः परधर्मात्स्वनुष्ठितात्।स्वधर्मे निधनं श्रेयः परधर्मो भयावहः॥
śreyān swa-dharmo viguṇaḥ para-dharmāt sv-anuṣṭhitātswa-dharme nidhanaṃ śreyaḥ para-dharmo bhayāvahaḥ
Word by word
The verse says
Better your own work, done badly, than someone else's work done well. It is better to die doing your own work. Someone else's work brings danger.
In plain words
Krishna is talking about the pull to live a life that is not yours.
The temptation is real, and it is not stupid. Someone else's path often looks cleaner. It is better paid, or better respected, or simply easier to explain to people. And you might be genuinely good at it. Krishna does not deny any of that. He says you should still not take it.
His word for the danger is strong: bhayāvaha, "bringing fear." Not failure. Fear. Something in you knows when you are performing a life instead of living one, and it does not go quiet.
Where you've felt this · at work
Someone is a careful, competent accountant. They are also the person who fixes things. Give them a broken chair and their whole face changes. They keep the steady job for twenty years, because it is sensible, and everyone agrees it is sensible. They are good at it. They are also slightly absent from their own life, in a way that is hard to name and never quite goes away.
Going deeper
This verse needs to be handled honestly, because it has been used badly.
The word is sva-dharma — your own dharma. In the Gita's own world, that meant in large part the duty of the social order you were born into, the varṇa system. Read that way, this verse says: stay in the station you were born to. That reading is not a modern invention or a distortion by outsiders. It is there in the text's historical setting, and Chapter 18 makes it more explicit. Pretending otherwise would be dishonest.
It should also be said plainly that this reading has done real harm. It has been used to tell people that a life they did not choose was a duty they must not leave.
So what is actually being argued? Underneath the social frame there is a psychological claim that does not depend on it. The claim is that a self has a grain to it, like wood, and that working against the grain costs you something you cannot get back. Krishna's point is not that some kinds of work are nobler. It is the opposite — he says your own work done badly beats another's done well. Quality is not the measure. Fit is.
The honest position is to hold both. The verse carries a social reading that has been used to trap people, and a psychological reading that most people recognise the moment they hear it. The traditions themselves split here, and a reader is better served knowing that than being handed one version as though it were the only one.
