मयि सर्वाणि कर्माणि संन्यस्याध्यात्मचेतसा। निराशीर्निर्ममो भूत्वा युध्यस्व विगतज्वरः।।3.30।।
mayi sarvāṇi karmāṇi sannyasyādhyātma-chetasā nirāśhīr nirmamo bhūtvā yudhyasva vigata-jvaraḥ
Renouncing all actions in Me, with the mind centered on the Self, free from hope and egoism, and from mental fever, fight thou.
