श्रेयान्स्वधर्मो विगुणः परधर्माद्स्वनुष्ठितात्। स्वधर्मे निधनं श्रेयः परधर्मो भयावहः॥
śhreyān sva-dharmo viguṇaḥ para-dharmāt sv-anuṣhṭhitāt
“Better to perform one's own duty imperfectly than to perform another's duty perfectly. Better is death in one's own duty; the duty of another is full of danger.”
This is the Gita's clearest statement on svadharma — your own specific duty versus a borrowed one. The word 'vigunah' means imperfectly — so this is not 'do your duty perfectly.' It is 'do your duty, even imperfectly.' A surgeon practicing law is more dangerous than a lawyer practicing law imperfectly. The point is not excellence; it is alignment with what you actually are.
यदा यदा हि धर्मस्य ग्लानिर्भवति भारत। अभ्युत्थानमधर्मस्य तदात्मानं सृजाम्यहम्॥
yadā yadā hi dharmasya glānir bhavati bhārata
“Whenever there is a decline in righteousness, O Arjuna, and a predominance of unrighteousness — at that time I manifest myself.”
This is the most famous 'dharma' verse — Krishna's explanation of why avatars appear. The maintenance of dharma is cosmic priority. When it declines past a threshold, the universe self-corrects. The verse is often quoted in political contexts (India, Mahabharata-style moral crises), but its personal application is this: when you sense that what is right is being overwhelmed by what is convenient, that is the moment that calls for action.
ब्राह्मणक्षत्रियविशां शूद्राणां च परन्तप। कर्माणि प्रविभक्तानि स्वभावप्रभवैर्गुणैः॥
brāhmaṇa-kṣhatriya-viśhāṁ śhūdrāṇāṁ cha parantapa
“The duties of Brahmins, Kshatriyas, Vaishyas, and Shudras are divided according to their qualities arising from their own nature.”
The Gita maps dharma to individual nature (svabhava), not just birth-determined caste. This verse is contentious in its social context — and the Mahabharata's history with caste is genuinely complicated — but the philosophical principle is worth separating: different natures genuinely have different dharmas. The teacher's dharma is clarity. The warrior's dharma is protection. The merchant's dharma is exchange. Knowing which one you actually are is the beginning of dharmic action.
श्रेयान्स्वधर्मो विगुणः परधर्मात्स्वनुष्ठितात्। स्वभावनियतं कर्म कुर्वन्नाप्नोति किल्बिषम्॥
śhreyān sva-dharmo viguṇaḥ para-dharmāt sv-anuṣhṭhitāt
“Better is one's own duty, even if imperfectly performed, than the duty of another performed perfectly. One who performs the duty dictated by one's own nature incurs no sin.”
This repeats Chapter 3's teaching — its reappearance in Chapter 18 (the final chapter) shows the Gita's deliberate emphasis. At the end of all eighteen chapters of philosophy, after discussing the soul, God, yoga, knowledge, devotion, and renunciation — this is where it arrives: do your thing. Not someone else's thing. Even imperfectly.
