Sloka 18.35
यया स्वप्नं भयं शोकं विषादं मदमेव च ।
न विमुञ्चति दुर्मेधा धृतिः सा पार्थ तामसी ॥
యయా స్వప్నం భయం శోకం విషాదం మదమేవ చ ।
న విముఞ్చతి దుర్మేధా ధృతిః సా పార్థ తామసీ ॥
yayā svapnaṃ bhayaṃ śokaṃ viṣādaṃ madameva ca |
na vimuñcati durmedhā dhṛtiḥ sā pārtha tāmasī ||
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.
