Sloka 18.47
श्रेयान्स्वधर्मो विगुणः परधर्मात्स्वनुष्ठितात् ।
स्वभावनियतं कर्म कुर्वन्नाप्नोति किल्बिषम् ॥
శ్రేయాన్స్వధర్మో విగుణః పరధర్మాత్స్వనుష్ఠితాత్ ।
స్వభావనియతం కర్మ కుర్వన్నాప్నోతి కిల్బిషమ్ ॥
śreyānsvadharmo viguṇaḥ paradharmātsvanuṣṭhitāt |
svabhāvaniyataṃ karma kurvannāpnoti kilbiṣam ||
About chapter 18
The final chapter brings the whole teaching together. Krishna explains true renunciation as giving up attachment to the fruits of action, describes how the three qualities shape knowledge, action, intellect and happiness, and teaches that doing one’s own duty is worship. He gives his final instruction — to surrender to him alone (18.66) — and Arjuna, his doubts gone, rises to do his duty.
