Bhagavad Gita 5.13 Chapter 5, Verse 13

सर्वकर्माणि मनसा संन्यस्यास्ते सुखं वशी ।
नवद्वारे पुरे देही नैव कुर्वन्न कारयन् ॥५.१३॥

sarvakarmāṇi manasā saṃnyasyāste sukhaṃ vaśī
navadvāre pure dehī naiva kurvanna kārayan

Meaning

Renouncing all actions in the mind, the self-controlled soul dwells happily in the city of nine gates (the body), neither acting nor causing action.
