Bhagavad Gita · 5.13

सर्वकर्माणि मनसा सन्न्यस्यास्ते सुखं वशी।नवद्वारे पुरे देही नैव कुर्वन्न कारयन्॥

sarva-karmāṇi manasā sannyasyāste sukhaṁ vaśhī nava-dvāre pure dehī naiva kurvan na kārayan

The self-controlled embodied being, having mentally renounced all actions, dwells happily in the city of nine gates — neither acting nor causing others to act.

— Bhagavad Gita 5.13
