श्रेयान्स्वधर्मो विगुणः
परधर्मात्स्वनुष्ठितात् ।
स्वभावनियतं कर्म
कुर्वन्नाप्नोति किल्बिषम् ॥

śreyān svadharmo viguṇaḥ paradharmāt svanuṣṭhitāt
svabhāvaniyataṃ karma kurvann āpnoti kilbiṣam

Kṛṣṇa (कृष्ण) is still speaking, to Arjuna (अर्जुन).

The verse

Better is one's own dharma, though faulty, than another's dharma well performed; doing the work fixed by his own nature, he does not obtain a stain.

नेपालीमा

दोष भए पनि आफ्नै धर्म, राम्ररी गरिएको अर्काको धर्मभन्दा श्रेष्ठ हुन्छ। आफ्नै स्वभावले तोकेको कर्म गर्दा उसले दाग पाउँदैन।

Where it sits

Arjuna's (अर्जुन) choice is his own dharma, fault and all, and the work his nature fixes brings no stain.

Split: श्रेयान् + स्व-धर्मः + विगुणः + पर-धर्मात् + सु-अनुष्ठितात् + स्वभाव-नियतम् + कर्म + कुर्वन् + न + आप्नोति + किल्बिषम्

The phrases

śreyān svadharmo viguṇaḥ paradharmāt svanuṣṭhitāt (श्रेयान्स्वधर्मो विगुणः परधर्मात्स्वनुष्ठितात्) is the comparison. One's own dharma, even faulty, is better. The ablative is the thing it is better than: another's dharma, and that other one well performed.

svabhāvaniyataṃ karma kurvan (स्वभावनियतं कर्म कुर्वन्) is the man in the act. Doing the work his own nature fixes.

nāpnoti kilbiṣam (नाप्नोति किल्बिषम्) is what he does not pick up. A stain. The participle kurvan (कुर्वन्) is the subject of āpnoti (आप्नोति).

Sanskrit in this line

The ablative answers "than" in a comparison. para-dharmāt (पर-धर्मात्) is "than another's dharma," and su-anuṣṭhitāt (सु-अनुष्ठितात्) agrees with it. śreyān (श्रेयान्), "better," is the comparative that needs that ablative. सु + अनुष्ठितात् su + anuṣṭhitāt is recited svanuṣṭhitāt (स्वनुष्ठितात्), because उ + अ u + a becomes va (व).

Say it back

Cover the English. Say which dharma is better. If viguṇaḥ (विगुणः) is thrown out and only the well-performed other dharma remains, stay here.
