Sloka 18.54
ब्रह्मभूतः प्रसन्नात्मा न शोचति न काङ्क्षति ।
समः सर्वेषु भूतेषु मद्भक्तिं लभते पराम् ॥
బ్రహ్మభూతః ప్రసన్నాత్మా న శోచతి న కాఙ్క్షతి ।
సమః సర్వేషు భూతేషు మద్భక్తిం లభతే పరామ్ ॥
brahmabhūtaḥ prasannātmā na śocati na kāṅkṣati |
samaḥ sarveṣu bhūteṣu madbhaktiṃ labhate parām ||
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.
